NTRODUCING IRISDOCUMENT
SERVER
IRISDocument Server is a powerful, high-productivity document
recognition server. It is designed to optimize, structure, index and
compress large volumes of image and PDF files and to convert
them into text-searchable and editable output files.
To process image files, IRISDocument Server uses I.R.I.S.'
proprietary OCR technology (Optical Character Recognition),
which supports as many as 137 languages. All American and
European languages are supported, including the Central-European,
Baltic and Cyrillic languages as well as Greek and Turkish.
A wide range of output formats are available: IRISDocument
converts image files into text-searchable PDF and XPS files and
into both text-searchable and editable Text, RTF, Word,
OpenDocument Text, HTML, XML, WordML and SpreadsheetML
files.
The PDF files you generate can be password-protected and digitally
signed. Also the PDF/A format, the standard format for long-term
archiving, is supported.
IRISDocument can also generate hyper-compressed PDF and XPS
documents. By means of iHQC, which stands for intelligent High-
Quality Compression, PDF documents can be compressed up to 200
times without loss of image quality. XPS documents can be
compressed up to 5 times. Three levels of iHQC are available for
PDF documents, and one level for XPS documents. iHQC Level I -
Chapter 1 – Introducing IRISDocument Server
10
Good Quality is available for both PDF and XPS documents in the
standard version of IRISDocument Server. To make full use of the
iHQC technology, an iHQC add-on is required.
Besides text recognition, IRISDocument offers powerful barcode
recognition for document structuring purposes. Barcodes in image
files can be used as separators to indicate where new documents
begin.
The IRISDocument Server Modules
IRISDocument Server consists of two main modules: Batch OCR
and Watched Folders.
The Batch OCR module allows you to process batches of
documents that are stored in a certain folder. One folder can be
processed at a time. Once the documents have been processed, they
are sent to an output folder.
In the Watched Folders module, IRISDocument Server
continuously monitors one or more folders, to which you can add as
many image files as you want. Each time new images are added,
IRISDocument will notice this and process them. IRISDocument is
designed for non-stop, around-the-clock processing. That's why the
Watched Folders module can also run as a Windows service. That
way, it can run unobtrusively in the background without a user
interface being displayed.
The IRISDocument Export features
The documents that are processed can be exported to other
applications by means of the Export feature. This export feature
can be boosted by means of the Workgroup add-on. By means of
this add-on you can define a workgroup of users who will be using
IRISDocument and export processed documents to their
corresponding e-mail addresses, personal folders and FTP folders.
Optionally, you can also export documents to Microsoft SharePoint
IRISDocument
TM
Server 9.5 – User Guide
11
websites via the Export to SharePoint add-on, and export them to
Therefore document solutions via the Export to Therefore add-on.
Using IRISDocument in combination with Canon
imageRUNNERS with iSend functionality and Canon
imageRUNNERS Advance
The Watched Folders module of IRISDocument can be used in
combination with Canon imageRUNNERS with iSend
functionality and Canon imageRUNNERS Advance. Users can
scan their documents on these MFP's and send them to the watched
folder(s) of IRISDocument. From there they can be processed and
exported via the Workgroup add-on.
Overview of the IRISDocument Server add-ons
iHQC add-ons are available to hyper-compress PDF and XPS
documents.
Three language add-ons are available:
o An Asian OCR add-on, which recognizes Traditional and
Simplified Chinese, Japanese and Korean documents.
o An Arabic OCR add-on, which recognizes Arabic and
Farsi documents.
o A Hebrew OCR add-on, which recognizes Hebrew
documents.
A Multi-CPU add-on is available. This add-on boosts the
processing speed of IRISDocument Server. IRISDocument
Server no longer processes OCR tasks one by one, but covers up
to 4 tasks simultaneously on PC's equipped with a multicore
processor or multiple CPU's.
An Export to SharePoint add-on is available. By means of this
add-on, you can publish processed documents on Microsoft
SharePoint websites.
Chapter 1 – Introducing IRISDocument Server
12
A an Export to Therefore add-on is available. By means of
this add-on you can export processed documents to Therefore
document solutions.
A Workgroup add-on is available. By means of this add-on you
can export processed documents to the e-mail addresses,
personal folders and FTP folders of all the users who belong to
the workgroup(s) you define in IRISDocument.

MODULES
THE BATCH OCR MODULE
The Batch OCR module allows you to process batches of
documents that are stored in a certain folder. One folder can be
processed at a time. Once the documents have been processed, they
are sent to an output folder.
To launch the module:
From the Windows Start menu, select
Programs>IRISDocument Server 9.5>Batch OCR.
In the sections on the left-hand side of the interface, you can
determine all the processing settings you want to apply.
Chapter 3 – IRISDocument Server Modules
20
You can also use the IRISDocument Wizard in the File menu to go
over the different steps in the right order.
When creating a watched folder, you will go through almost exactly
the same steps. These steps will be discussed only once for both
Batch OCR and Watched Folders in the corresponding sections
below.
When you have covered all the steps, an overview of the settings
will be given on the Summary tab.
To start processing your documents, open the File menu, save
the settings and click the Run command.
The files and folders will be processed in alphabetic order. An
application window displays the progress.
IRISDocument
TM
Server 9.5 – User Guide
21
As soon as the batch OCR process is completed, the lower part
of the application window displays a batch report.
More information about the OCR process is available in the
automatically generated log files, xml index files and confidence files,
which are located in the output folder. See the section XML indexing.
THE WATCHED FOLDERS MODULE
In the Watched Folders module, IRISDocument acts as an OCR
server. IRISDocument Server continuously monitors one or more
folders, to which you can add as many image files as you want.
Each time new images are added, IRISDocument will notice this
and process them.
The Watched Folders module is designed for non-stop, around-
the-clock processing.
It is recommended not to use more than 10 watched folders.
Chapter 3 – IRISDocument Server Modules
22
The Watched Folders module can be used in combination with
Canon imageRUNNERS with iSend functionality and Canon
imageRUNNERS Advance.
To launch the module:
From the Windows Start menu, select
Programs>IRISDocument Server 9.5>Watched Folders.
When you run IRISDocument Server for the first time, you will
be prompted to indicate a work folder in which IRISDocument
stores all temporary data that is being processed, such as image
and log files, and temporary and undelivered results.
This work folder should be located on a hard disk that has sufficient
free memory.
Note: if you installed the Workgroup add-on and selected
Workgroup initial data during the installation, then a complete
Watched Folder configuration will be preconfigured. The
preconfigured work folder will be located in
C:\IRISDocument_9.5\Storage.
Select a location, or create a new one on your computer, which
you want to use as work folder.
IRISDocument
TM
Server 9.5 – User Guide
23
Note that IRISDocument Server must have fast access to the work
folder. Therefore, it is mandatory you select or create a folder on a
local hard disk instead of on a network. Bandwidth and network
issues, such as time-outs, inconsistent time or time zone settings etc.,
might slow down IRISDocument Server considerably.
As soon as you click OK, the empty user interface will open.
Open the File menu and click the command Create a Watched
Folder.
You will be guided through the various setup steps in the proper
order. Once you are finished selecting the different options, the
user interface will appear again.
Chapter 3 – IRISDocument Server Modules
24
This order is very similar to the one of the IRISDocument Wizard in
the Batch OCR module and is discussed only once in the
corresponding sections below.
Any options you selected can still be changed using the sections on
the left-hand side. Any changes you make will be saved automatically.
To start monitoring Watched Folders, open the File menu and
click the Run command.
The user interface displays the tasks in progress.
The processing can be aborted by means of the Abort command
in the File menu.
Note that aborting the process may take some time. IRISDocument
always finishes the task in progress before interrupting. Watched
folders cannot be created, edited or removed when the OCR is in
progress.
When the process is aborted, the lower part of the interface displays
the pending tasks and their status.
IRISDocument
TM
Server 9.5 – User Guide
25
The status of the various OCR tasks can also be verified in the work
folder.
The pending tasks can be edited in the Task menu: select the tasks
you want to edit in the lower part of the application and click the
command Edit selected tasks.
WATCHED FOLDERS AS A WINDOWS SERVICE
The Watched Folders module can run as a Windows service. This
way, IRISDocument can run unobtrusively in the background and
without interference for long, uninterrupted periods of time on a
computer that is also used for other tasks.
Note that Microsoft .Net Framework version 1.1 is required.
In order for the Watched Folders module to run as a Windows
service, it must first be registered.
Registering Watched Folders as a service
From the Windows Start menu, click
Programs>IRISDocument Server 9.5>Watched Folders
Service - Register.
Then, run the application services.msc from the Windows Run
menu to view the Windows services.
Search for IRISDocument Watched Folders Service in the
Services list.
If IRISDocument Watched Folders Service is not in the list, it did not
register correctly.
Check the status of IRISDocument Watched Folders Service. If
the status does not say 'Started', then right-click IRISDocument
Watched Folders Service and click Start.
Chapter 3 – IRISDocument Server Modules
26
Monitoring Watched Folders as a service
To monitor Watched Folders as a service, select Watched
Folders Service Monitor from the Windows Programs menu.
If you started the service in the Service list during the previous
step, then the Start button will be disabled and the service is
already running. If the Start button is still enabled, click it to
start the service.
IRISDocument Watched Folders Service uses the settings you
determined in the Watched Folders module.
The Watched Folders Service automatically generates an HTML
log file. Click the Show log file button to display it.
It is located in the subfolder html of the work folder and lists the
current tasks and processes.
Note: Some (network) features of the Windows operating system are
handled by services. The order in which different services are started
may play a role in the proper operation of IRISDocument Server.

NPUT SOURCE
BATCH OCR IMAGE FOLDER
In order to process batches of documents, you must indicate in
which folder your documents are located.
Start the Batch OCR module from the Windows Start
menu>Programs>IRISDocument Server 9.5.
The interface will open and the File Scanner tab of the Input
section will be displayed.
Click the Browse button and search for the folder you want to
process.
IRISDocument by default processes the subfolders of the
indicated folder.
Chapter 4 – Input Source
28
IRISDocument does not delete the images from the image folder
by default, but you can choose to delete them after recognition.
It is recommended to use a local hard disk as image folder, rather than
a network volume. The recognition is faster and bandwidth and
network issues are avoided.
Options
IRISDocument by default loads PDF and DjVu documents in
color. Should you want to load these documents in black-and-
white to reduce the processing time, then clear this option.
When you need to process many PDF documents from different
sources, among which PDF documents that already contain text,
and you want to generate PDF Image-Text output documents, it
is useful to select the option Don't modify PDF containing text.
By selecting this option, IRISDocument Server will not convert
the PDF files that already contain text into PDF Image-Text files.
Instead, IRISDocument will simply copy the original files to the
output folder. This way, unnecessary processing is avoided.
So this option is useful if your batches of input documents
contain PDF files of which you do not know the content (text,
images, or both?). IRISDocument considers a PDF file to contain
text when there are more than 10 characters per page.
Important note: the option Don't modify PDF containing text is not
compatible with options that require modifying the input PDF (e.g.
password protection, document structuring). That's why the following
number of parameters need to be configured:
The selected output format must be PDF Image-Text (in the
Output section, on the PDF tab)
In the Processing section, on the Barcode Reading tab:
Enable barcode reading must not be selected (not selected
by default).
IRISDocument
TM
Server 9.5 – User Guide
29
In the Batch Output section, on the Separation tab:
Select Create one document per input file.
Do not select Use blank pages to separate documents.
Make sure Keep blank pages is selected (default
option).
In the Batch Output section, on the XML Indexing tab:
Deselect XML Indexing (default option).
Deselect Include recognized text (default option).
In the Document Output section, on the PDF tab:
Do not select Create PDF/A compliant files.
Do not apply Password security.
Do not select Signature to apply.
In the Document Output section, on the PDF-iHQC tab:
Do not select Create PDF/A compliant files.
Do not apply Password security.
Do not select Signature to apply.
In the Document Output section, on the Document Names
tab: do not select the option Use first sentence of
recognized text.
Also note that when you select other output formats besides PDF
Image-Text, the input PDF will be processed and converted into those
required output formats.
When processing PDF documents, IRISDocument first converts
them into image files (This process is called rasterization). The
image files are then processed and converted into output
documents.
Chapter 4 – Input Source
30
The resolution at which IRISDocument extracts image files from
PDF documents can be determined: select the appropriate
resolution in the drop-down list, right of Load PDF at:
o IRISDocument by default loads PDF documents at 300
dpi.
o Select 200 dpi to increase the processing speed.
o Select 600 dpi to increase the processing accuracy.
WATCHED IMAGE FOLDER
In this section you indicate which image folder IRISDocument
must monitor as Watched Folder.
Start the Watched Folders module from the Windows Start
menu>Programs>IRISDocument Server 9.5.
o If you are using the standard version of IRISDocument
Server and you are starting the Watched Folders module
for the first time, you will be prompted to indicate a work
folder in which IRISDocument will store temporary data
such as log files. See the section The Watched Folders
module.
o If the Workgroup add-on is installed and you selected
Workgroup initial data during the installation, then a
IRISDocument
TM
Server 9.5 – User Guide
31
complete Watched Folder configuration will be pre-
configured and the interface will open immediately.
In case you want to use a Canon imageRUNNER to send
documents to IRISDocument, make sure you install the
Workgroup add-on and select the Workgroup initial
data option.
You are recommended not to change the pre-
configured settings that are applied (except for the
Watched Folder location should you want to change this).
The pre-configured image folder of the Watched Folder is
C:\IRISDocument_9.5\WatchedFolder01\Input.
When configuring the Canon imageRUNNER, you will
need to enter the name of the Watched Folder. In this case:
\Input. Refer to the sections Configuring a Canon
imageRUNNER with iSend functionality or
Configuring a Canon imageRUNNER Advance for
more information.
When creating additional Watched Folders, make sure to
apply the same settings as in the pre-configured one.
Note: the Canon imageRUNNER must have reading and
writing rights to the Watched Folder in order to be able to
send documents to it. If the user account that is used to
configure the Canon imageRUNNER (in the remainder of
this documentation referred to as the MFP administrator) is
not the same as the user account on which IRISDocument
is installed and configured, then the Watched Folder must
be shared with the MFP administrator. Refer to the section
Sharing folders for more information on how to share
folders.
Chapter 4 – Input Source
32
To create a new Watched Folder, open the File menu and click
Create a Watched Folder.
Click the Browse button to search for the appropriate folder.
Warning: it is mandatory to select a folder on a local hard disk
instead of on a network. Bandwidth and network issues, such as time-
outs, inconsistent time or time zone settings etc., might slow down
IRISDocument Server considerably. Therefore, I.R.I.S. does not
guarantee the proper operation of the Watched Folders module when
monitoring a network folder.
Image folder
IRISDocument Server can either Process the root of a selected
folder or Process the subfolders.
When processing the root of a selected folder, the images are erased
automatically from that folder once they have been processed.
Otherwise, they would be processed over and over again.
When processing the root, of a selected folder, IRISDocument also
processes the images that are located at 1 level below the root.
When processing the subfolders, the root folder is ignored and only
the subfolders are processed. The images and subfolders are deleted
after task creation by default, and stored in the work folder. You can
also choose to keep a copy of the documents in their original folder by
clearing the box Delete document after task creation. These
documents will not be processed over and over since IRISDocument
Server can detect which documents are already being processed by
means of run files.
IRISDocument
TM
Server 9.5 – User Guide
33
End of task detection
The End of task detection options allow you to determine how the
stream of scanned images will be broken up in separate tasks.
Time-out
If the contents of a watched folder do not change for a certain time,
IRISDocument Server will start converting all documents in that
folder as a single task.
File detection
When processing subfolders, you can drop an end of task file
(eod.inf) in a watched folder. As soon as IRISDocument Server
encounters the file, it will know the task is completed and it will
start the next one. All documents up to the eod file will be
processed as part of a single task. Note: make sure to arrange you
documents in the right order up to each eod file. Otherwise your
output documents will be processed incorrectly.
For each task indicated by an end of task file, IRISDocument Server
creates a run file in the image folder, to indicate to the user that this
specific task is being processed.
All images for which a run file exists are ignored as the folder
monitoring continues. This way, the images do not need to be
removed from the source image folder.
Note, however, that the End of task detection settings are not the
only way to organize a stream of scanned documents. There are also
specific document separation options to select. Refer to the section
Document Separation to learn more.
Chapter 4 – Input Source
34
Processing
IRISDocument Server handles several watched folders
simultaneously. The watched folder with the highest priority is
processed first.
Open the Task menu to change the priority of specific tasks. Note,
however, that the Task menu cannot be opened when the OCR is in
progress; the current process needs to be aborted first.
Options
IRISDocument by default loads PDF and DjVu documents in
color. Should you want to load these documents in black-and-
white to reduce the processing time, then clear this option.
When you need to process many PDF documents from different
sources, among which PDF documents that already contain text,
and you want to generate PDF Image-Text output documents, it
is useful to select the option Don't modify PDF containing text.
By selecting this option, IRISDocument Server will not convert
the PDF files that already contain text into PDF Image-Text files.
Instead, IRISDocument will simply copy the original files to the

DEFINING A WORKGROUP OF USERS
(This section only applies to the Watched Folders module when
the Workgroup add-on has been installed)
If you installed the Workgroup add-on as part of your
IRISDocument Server configuration, then the Workgroup tab will
be available in the Input section of the Watched Folders module.
Note that the Workgroup add-on only applies to the Watched
Folders module.
Via the Workgroup tab you can define workgroups of users who
will be using IRISDocument to process documents (possibly via a
Canon imageRUNNER).
For each user you create a profile, containing the user's identifier
and the e-mail address, personal folder and FTP folder to which
the documents must be exported after processing. These profiles are
stored in a Workgroup XML file. By default, this file is located in
C:\IRISDocument_9.5\Storage\system.
The default workgroup file can be edited and new workgroup files
can be added by means of the Workgroup Editor.
To define a workgroup of users:
Open the Input section and click the Workgroup tab.
Chapter 4 – Input Source
38
When you are using Watched Folders for the first time, refer to the
section The Watched Folders module.
Select the option Enable user identification. Otherwise, you
will not be able to define a workgroup.
You can choose to Extract the user information from the
input file name.
When you select this option, IRISDocument will look at the file
name of the documents to know to which user they belong, and
to which export destination they must be sent. If you select this
option, make sure that your documents carry the correct name.
When you do not use this option, IRISDocument will extract the
user information from the eod files that must be delivered with
the input files. Note that when no eod files are delivered,
IRISDocument will not be able to export the documents
correctly. Also note that you must select the option File
detection on the Watched Folder tab if you want to use this
option.
If you selected Workgroup initial data during the installation of
the Workgroup add-on, then a pre-configured workgroup file
will have been created:

The Workgroup Editor will open.
First configure the default user.
If IRISDocument is not able to send documents to a certain user,
because the fine name is incorrect for instance, then the
documents are sent to the default user. Thus, the default users
must always be configured correctly.
Enter the E-mail, Folder and FTP folder fields.
Click New to enter a new user.
You are required to enter an Identifier for each user.
When you select the option Extract user information from the
input file name on the Workgroup tab, IRISDocument will use
the identifier to know to which user the documents belong.
The identifier can be up to 24 characters long.
Note: when users are sending their documents via a Canon
Chapter 4 – Input Source
40
imageRUNNER to IRISDocument, they must enter the identifier
as document name (or this can be configured by the MFP
Administrator in case of the imageRUNNER Advance). Based
on the Identifier, IRISDocument knows to which destination the
processed documents must be exported.
Refer to the appendix Configuring Canon imageRUNNERS to
run with IRISDocument for more information.
Then enter the Last name, First name, E-mail address,
Personal folder and/or FTP folder for the user.
Important: IRISDocument must have reading and writing access to
each user's personal folder. Otherwise IRISDocument will not be able
to export the processed documents to that folder. In other words, each
user's personal folder must be shared with the IRISDocument
Administrator.
To apply the correct sharing settings, refer to the section Sharing
folders.
To keep adding users manually, repeat this process. Then click
OK and save the Workgroup file, by clicking File>Save.

Similarly, IRISDocument needs to have reading and writing access
to users' personal folders if it is to export them via the Workgroup
add-on.
Thus it is important for these folders to be shared.
Note that FTP folders must not be shared.

ARCODE READING
Next to optical character recognition of up to 137 languages,
IRISDocument also offers barcode reading. Barcodes can be used to
provide indexing data, to name documents and to separate
documents within a batch.
IRISDocument reads both 1D and 2D barcodes and supports laser
printed and inkjet printed barcodes.
All widespread barcode symbologies are supported: Codabar, Code
128, Code 39, Code 39 extended, Code 39 HIBC, Code 93,
Datalogic 2 of 5, Discrete 2 of 5, EAN-13, EAN-2, EAN-5, EAN-8,
IATA 2 of 5, Interleaved 2 of 5, MSI pharmaceutical, MSI-Plessey,
PDF-417, PostNet, PostNet 32, PostNet 52, PostNet 62, QR Code,
Reverse 2 of 5, UCC-128, UPC-A, UPC-E and UPC-E extended.
To enable barcode reading:
Open the Processing section and click the Barcode Reading
tab.
When you are using Watched Folders for the first time, refer to the
section The Watched Folders module.
Chapter 6 – Barcode Reading
52
Check the box Enable barcode reading and select the desired
barcodes.
Do not select barcodes that do not apply: the bigger the barcode set,
the slower the recognition and the higher the risk of OCR errors will
be.
Select the options you want to apply:

encoded. Use this option for those symbologies that do not put strict
limits on the length of barcodes.
IRISDocument
TM
Server 9.5 – User Guide
53
Advanced features
As barcodes can be used to separate various documents in a batch,
IRISDocument allows you to remove them from the output
documents.
Barcodes are always placed on the front side of a document.
Therefore, IRISDocument can limit barcode reading to front pages
when scanning double-sided documents.
For more information, refer to the appendix on Barcode reading.

HARACTER RECOGNITION
The accuracy of the OCR process depends on many factors, such as
the selected language, the document characteristics, etc.
To access the character recognition options:
Open the Processing section and click the Character
Recognition tab.
When you are using Watched Folders for the first time, refer to the
section The Watched Folders module.
Select the required character recognition options:
Chapter 7 – Character Recognition
56
Language
In order to recognize documents, the document language must be
specified. Based on the language selection, the software knows
which symbol sets to recognize.
Select the language of your choice in the Language drop-down list.
IRISDocument supports up to 137 languages. IRISDocument can
optionally recognize four Asian languages (Traditional and Simplified
Chinese, Japanese and Korean), Arabic and Farsi, and Hebrew.
IRISDocument also recognizes barcodes and banking fonts. Refer to
the appendices to the User Guide for more information on barcodes
and banking fonts.
Note that the character recognition can also be limited to numeric
digits.
Secondary languages
Next to the primary language, IRISDocument allows you to select
up to 4 secondary languages.
This way, IRISDocument uses mixed character sets, enabling it to
recognize Western words that occur in Greek, Cyrillic and
optionally Asian, Arabic or Hebrew documents.
Select the required secondary languages in the list.
Note that if you select multiple secondary languages they must be of
the same language group. Languages that do not belong to the same
group will be disabled automatically.
Do not select languages that do not apply: the bigger the character set,
the slower the recognition and the higher the risk of OCR errors.
Character pitch
The character pitch is the number of characters per inch in a
typeface.
IRISDocument
TM
Server 9.5 – User Guide
57
Select fixed pitch if all characters of the typeface have the same
width. This is often the case in old typewriter documents.
Select proportional pitch when the characters of the typeface have
a different width. Virtually all fonts you find in newspapers,
magazines and books are proportional.
Select Automatic in order for IRISDocument to detect the character
pitch automatically.
Note: the character pitch option does not apply to Asian or Arabic
documents.
Font type
IRISDocument distinguishes between "regular" and dot matrix
printed documents.
Dot matrix symbols (of the type 9 pin) are made up of isolated,
separate dots.
Special segmentation and recognition techniques are used to
recognize such documents.
Chapter 7 – Character Recognition
58
Select Dot matrix to recognize so-called "draft" or "9 pin" dot
matrix printed documents and Automatic to recognize "25 pin" or
"NLQ" (Near Letter Quality) dot matrix, or other "normal" printing.
Note: the Font type option does not apply to Asian, Arabic or Hebrew
documents.
Page range
The character recognition can be applied to all pages, no pages and
a certain number of pages.
The third option allows you to mix text-based and image-based
pages in a single PDF or XPS file.
To create a mixed PDF/XPS file:
Open the Processing menu and click the Character
Recognition tab.
In the Page range section, select the option X first page(s).
The number of pages you indicated will be recognized. The
pages following that number will only be scanned.
This option increases the speed of the OCR process by avoiding the
recognition of irrelevant pages and reduces the file size of the output.
User lexicon
The OCR accuracy can be boosted by means of customized user
lexicons.
To create and use a user lexicon:
From the Windows Programs menu, select IRISDocument
Server 9.5.
Launch the application User Lexicon Editor.
IRISDocument

When you are using Watched Folders for the first time, refer to the
section The Watched Folders module.
Click the Browse button and select the correct user lexicon.
Note that in order for IRISDocument to recognize the words in the
user lexicon, the correct language must have been selected under the
Character Recognition tab.
Recognition
The recognition slide toolbar allows you to select the right trade-off
between OCR speed and OCR accuracy.
Fast recognition can be used for documents with high-quality
images while Accurate recognition should be preferred when the
image quality is lower.
Chapter 7 – Character Recognition
60
The confidence level of the OCR process can be checked in the log
file IRISDOCUMENT.HTML.
This trade-off between speed and accuracy is available for the Latin,
Cyrillic and Greek alphabets.
READING BANKING FONTS
Next to 137 recognition languages, IRISDocument also recognizes
banking fonts thanks to its highly specialized magnetic ink
character recognition engines.
These recognition engines handle - with very high accuracy and
without substitution of the dubious symbols - the data input of the
optical lines as are found on bearer bonds, coupons, checks, deposit
slips, bank statements and other standardized financial (negotiable)
documents.
To enable bank font reading in the Batch OCR or Watched
Folders module:
Open the Processing section and click the Character
Recognition tab.

MAGE COMPRESSION
GENERAL IMAGE COMPRESSION
IRISDocument allows you to generate compact images. The images
in scanned documents can be compressed and their color mode and
output resolution changed by means of extensive image
compression options.
To access these options:
Open the Image Compression section and click the General
tab.
When you are using Watched Folders for the first time, refer to the
section The Watched Folders module.
Select the appropriate image compression options:
Note: take your storage limitations into account when selecting these
options.
Chapter 8 – Image Compression
64
Color mode of output images
You can either choose to maintain the color mode of scans or save
scans in black-and-white.
When you have chosen to maintain the color mode of scans while
generating PDF documents, color and grayscale graphics will be saved
in the JPEG format by default.
Bitonal images (black-and-white) are saved in the TIFF format with
Group 4 compression.
Resolution of output images
The resolution used to scan images does not necessarily have to be
the output resolution of the images. You can store images in
resolutions of 75, 100, 150 and 200 dpi or keep their original
resolution.
Note, however, that reducing the resolution of grayscale and color
images is a processor-heavy task. When generating color-grayscale
images, reducing the resolution is not recommended.
Compression of output images
Use the slider to determine the compression factor of JPEG images.
IRISDocument
TM
Server 9.5 – User Guide
65
Note that the settings determined under the General tab apply to all
graphics generated by IRISDocument.
JPEG 2000 COMPRESSION
Next to the general image compression options, IRISDocument
allows you to apply JPEG 2000 compression to color and
grayscale images.
Note that JPEG 2000 compression does not apply to iHQC documents
as iHQC is 15 times more efficient.
To access the JPEG 2000 compression options:
Open the Image Compression section and click the JPEG 2000
tab.
When you are using Watched Folders for the first time, refer to the
section The Watched Folders module.
Select the options of your choice:
Chapter 8 – Image Compression
66
Compression
The file size of scanned images can be influenced in several ways:
Select lossless compression for optimal results.
The Compression ratio allows you to determine how many
times you want the scanned images to be smaller than their
original.
You can also determine the desired target size of a single page
in the output file.
Indicate the file size for a single page from 1 KB to 10,240 KB. The
default value is 100 KB.
Select a Quality factor to determine the degree of loss allowed
during the compression process.
Move the slide toolbar to select a value from 0 to 256: 0 guarantees
the highest image quality, 256 the best compression. The default value
is 128.
Optimization
Optimize quality of text zones maintains a high quality for text
and table zones, reducing the quality of graphic zones in the
output images.
Optimize quality of graphic zones has the opposite effect.
Note that character recognition must be enabled for these options to
be available; otherwise the system can't detect which zones contain
text and which areas contain graphics.

Separators
IRISDocument can create a new document each time it encounters a
blank page or barcode..
Note that barcode reading must be enabled in order to use barcodes as
separators.
A page is blank to IRISDocument when no text, barcodes or graphics
are recognized. A blank page only contains noise.
Blank pages and pages containing barcodes can either be
maintained in or removed from the output documents.

index file, containing detailed information on the scanned
documents, including the recognized text.
To access the XML indexing options, open the Batch Output
section and click the XML Indexing tab.
When you are using Watched Folders for the first time, refer to the
section The Watched Folders module.
Note: do not confuse the generation of an XML index file with the
generation of XML output.
The information in the XML file is used to export your processed
documents to other applications. For more information see the section
Export features.
Other OCR statistics
Next to an XML index file, IRISDocument automatically generates
a log file and an OCR confidence file after document processing.
These files are located in the output folder of IRISDocument.
The log file lists all OCR parameters determined in IRISDocument.
Chapter 10 – XML Indexing
70
In the Batch OCR module, one log file is created per batch.
In the Watched Folders module, one log file is created per task.
The OCR confidence file allows you to monitor the confidence of
the OCR process by means of two charts providing word-based and
character-based statistics.
Should the confidence level not be satisfactory, ask yourself the
right questions. E.g. Have the settings been determined correctly?
Do the scanned documents have a sufficiently high resolution? Has
the correct language been selected?

Any prefix can be added in front of this sequential name.
o The naming option Use indexing fields only applies to
IRISDocument Server for IRISPowerscan. In order to use
an index field as document name, you must first create
index fields in IRISPowerscan.
o When you select Use Name of first image, all your output
documents will start with the name of the first input file in
the batch or watched folder that was processed by
IRISDocument. E.g. SampleDocument,
SampelDocument0, SampleDocument01, ...
Chapter 12 – Document Naming
74
o When you are processing multiple image folders each
containing image files that belong together, select the
naming option Use name of image folder. Your output
documents will be named ImageFolder0, ImageFolder1 for
instance.
o You can also use the content of a specific barcode in your
document as document name. Select the option Use
content of barcode and indicate which barcode in the
document must be used as document name.
o Or you can use the content of the barcodes on the first page
as document name. Select the option Use content of first-
page barcodes and indicate at which barcode
IRISDocument must start.
o The first sentence of the recognized text can also be used
as naming option.
o When generating PDF and PDF-iHQC output files at the
same time, or XPS and XPS-iHQC output files at the same
time, a suffix is added to the document name by default:
e.g. document.ihqc.pdf. This way a clear distinction is
made between regular PDF and XPS documents and their
iHQC-compressed counterparts. This suffix can be
changed to your liking.
Note: when you are only generating PDF-iHQC output
files, and no 'regular' PDF files, no suffix is added to the
files. The same goes for XPS-iHQC files.

Note:
The name a user gives to a document when sending it via the MFP
should be his personal identifier that was attributed to him by the
IRISDocument Administrator via the Workgroup Editor (see the
section Defining a workgroup of users for more information.)
Based on this identifier, IRISDocument knows to which user the
documents belong and to which destination the processed
documents must be exported.
The identifier will be added in front of the default name attributed
by the MFP: e.g. DGI_20100430142523. The standard name
consists of the year, month, day, hour, minute and second the
document was processed by the MFP.

IRISDocument generates four types of PDF files: Text, Text-
Image, Image-Text and Image.
IRISDocument also generates both password-protected and
digitally signed PDF output and offers PDF/A output for long-time
preservation.
IRISDocument can also apply iHQC compression to reduce the
file size of PDF output to a minimum.
To generate PDF output:
Open the Document output section and click the PDF tab.
When you are using Watched Folders for the first time, refer to the
section The Watched Folders module.
Select the desired PDF type in the Type drop-down list: PDF
Image, PDF Image-Text, PDF Text or PDF Text-Image.

PDF Image-Text
IRISDocument recognizes text and creates searchable PDF files
that contain the page image and the recognized text.
The page image is placed on top of the text.
With this format you can search words inside documents and view their
true image as it was scanned.
Tip: use the graphics options in the Image Compression section to
determine the color mode, resolution and JPEG quality of the graphics
stored inside PDF files.
Tip: use the image enhancement options in the Processing section to
improve the image quality and reduce the file size of PDF Image and
Image-Text files.
Note that iHQC compression is available for PDF Image and Image-
Text.
PDF Text
IRISDocument recognizes text and creates searchable PDF files.
The page image is not contained in these single-layered PDF files.
Tip: use text-only PDF files to save disk space.
PDF Text-Image
IRISDocument recognizes text and creates searchable PDF
documents that contain the page image and the recognized text.
The page image is contained beneath the text.
The pixels of the recognized text are erased to create a legible document.
Otherwise, the text would have a heavy shadow as illustrated below:

Digitally signed PDF
Next to regular and password-protected PDF output, IRISDocument
offers digitally signed PDF, PDF/A, PDF-iHQC and PDF/A-
iHQC output.
Digital signatures authenticate the identity of the document author,
certify a document and help prevent unwanted changes. They are
very hard to forge as they contain encrypted information unique to
the signer.
The author signature is invisible: it appears in the Signatures tab of
Adobe Acrobat and Adobe Reader. To ensure legibility of all
scanned information, IRISDocument does not place a signature on
the pages of recognized documents.

Important: When producing PDF Text files, IRISDocument
embeds all fonts automatically in PDF/A output to ensure that
documents can be opened and viewed as created in the future.
When producing PDF Image-text files, however, IRISDocument
now offers PDF/A files without embedded fonts. As the text is
IRISDocument
TM
Server 9.5 – User Guide
87
placed beneath the image, no font embedding is necessary. This
way, IRISDocument produces more compact PDF/A output while
the document text is still searchable and copyable.
Notes:
To avoid data loss, PDF/A files cannot be password-protected.
PDF/A compliant files do not support JPEG 2000 compression.
PDF/A compliant files are not compatible with iHQC Level III or
with custom compression.
PDF/A compliant output is currently not available for Asian
languages.
It takes Adobe Acrobat 5.0 (or Adobe Acrobat Reader 5.0) or
higher to generate and open PDF/A files.
PDF - iHQC
Next to four types of regular PDF files, IRISDocument also offers
two types of PDF-iHQC output: PDF Image-text and PDF Image.
iHQC stands for intelligent High-Quality Compression, I.R.I.S.'

Layout
Create body text avoids text formatting by IRISDocument.
Retain word and paragraph formatting takes an intermediate
position between body text and autoformatting.
The font type, size and type style are maintained across the
recognition.
The tabs and the alignment of each block are recreated.
The text blocks and columns aren't recreated; the paragraphs just
follow each other.
The tables are recaptured correctly.
These two options are also available for SpreadsheetML output.
Recreate source document recreates a facsimile copy of the
original document.
You get a true copy of your source document, no longer a scanned
image.
Use columns instead of frames determines how the
autoformatting will be done: the text blocks, tables and graphics
can be stored in frames or flowing columns (if any).
Columnized texts are easier to edit than documents containing several
frames: the text flows naturally from one column to the next.
Note: when the system is unable to detect columns in the source
document, this formatting mode uses frames as a fallback position.
Note that this option is not available for HTML output.
Insert column breaks determines whether you insert hard
column breaks at the end of each column.
Any text you edit, add or remove, remains inside its column; no text
ever flows automatically across a column break.
Chapter 13 – Output Formats
96
Tip: disable this option when you have columnized body text. You'll
ensure the natural flow of the text from one column to the next.
Note that this option is not available for HTML output.
The option Add image as page background places the scanned
image as page background beneath the recognized text.
The pixels of the recognized text are erased to create a legible
document. Otherwise, the text would have a heavy shadow as
illustrated below:
This option increases the file size of the output files substantially,
however.
Note: this option is not available for WordML files.
The format PDF Text-Image provides the same result for PDF files.
The option Retain colors of background provides a less drastic,
more compact alternative, as illustrated above.
Note that IRISDocument detects any web page URLs and e-mail
addresses in scanned documents and recreates them as hyperlinks in
the output.
Options
Merge lines into paragraphs enables automatic paragraph
detection.
IRISDocument wordwraps the recognized text until a new paragraph
starts and reglues hyphenated words at the end of a line.

Retain colors of text maintains the original colors of the text
across the recognition.
Retain colors of background maintains the spot colors of the
page background across the recognition.
A uniform background color - if there is one in the source document -
is created per paragraph in the output file.
This option also recreates inverted drop letters.
The option Add image as page background offers a more drastic,
less compact alternative, as illustrated above.
Retaining the colors of the background implies that the colors of the
text are maintained simultaneously.

The text is not legible to the human eye because the XML document
contains detailed formatting information (type styles, position of
each character on the page etc.). The text is stored character by
character, word by word.
It takes an XML parser to make sense of the XML output.
IMAGE FILES
Alongside several text formats, IRISDocument offers image output.
Images can be exported as BMP, JPEG, JPEG 2000 and TIFF files.
To generate image output:
Open the Document Output section and click the Image files

o The following graphic formats are supported for color-
grayscale images: JPEG, JPEG 2000, TIFF and
multipage TIFF (both with JPEG and JPEG 2000
compression) and Windows bitmaps.
Tip: use the image enhancement options in the Processing section to
improve the image quality.
Warning: Windows bitmaps do not offer any compression. A single
A4 color page may take some 25 MB disk space on your hard disk.

EXPORT APPLICATION
After you have processed your documents with IRISDocument,
they can be exported automatically to other applications by means
of the custom export feature.
The custom export feature connects IRISDocument to external
applications that, for instance, open the processed documents in a
viewer, import them in an imaging system, republish them on an
intranet server, inform users by e-mail that new material is
available, etc.
To export documents to other applications, the custom export
feature makes use of the XML index that IRISDocument generates
by default. As a result, you need to select custom export
applications that are capable of parsing the XML index files
generated by IRISDocument.
Note: when the Workgroup add-on is installed and the options
Extract subfolder name from first-page barcodes or Extract
subfolder name from barcode are selected, the export application
will be disabled on the Export tab.
To select an export application:

Using the IRISDocument templates
IRISDocument makes use of templates when exporting documents
to Therefore. In each template you indicate to which Category you
want to export your documents and which Document title field
must be used as document name in Therefore.
After you have created all the necessary document types, you can
create IRISDocument templates.
Click New to create a new template or click Edit to modify the
default template.
Note that you must always use the template settings to configure the
Therefore settings. The Therefore settings cannot be configured in the
initial screen.
When you selected a new template, enter the name of the
template.
Click Enable this template to activate it.
The button Define field mappings only applies when you are
using IRISDocument for IRISPowerscan.
Click OK to close the template settings.
The next time you process your documents, they will be sent to
Therefore.

EXPORT TO PERSONAL FOLDERS
(This section only applies to the Watched Folders when the
Workgroup add-on is installed)
If the Workgroup add-on is installed as part of your
IRISDocument Server configuration, the Folder tab will be
available in the Export section of the Watched Folders module.
The settings on this tab allow you to export documents to personal
folders after they have been processed. You can either export

of users to learn how to configure the workgroup file correctly.
Also note that:
In order for the 'barcode' options to be available, the option Barcode
Reading must be selected in the Processing section on the Barcode
Reading tab.
In order to generate personal folders based on barcodes, the
documents you process need to contain barcodes, which in turn, need

If the folder path is contained in a specific barcode, select
Extract full folder path from barcode and indicate which
barcode in your document contains the folder path.

CHAPTER 15
IRISD
OCUMENT GOLDEN RULES
To conclude this User Guide, here is a list of golden rules for using
IRISDocument Server.
Please follow these rules to ensure optimal use of IRISDocument:
Use a dedicated PC with a good processor and a lot of RAM.
Refer to the ReadMe file for recommended system requirements.
Use the Watched Folders module whenever possible instead of
the Batch OCR module.
The Watched Folders module has extra error handling functionalities,
meaning the application will not stop even if an error is encountered.
The problem will be noted and IRISDocument will continue working
on the other tasks.
Do not select a network folder as input, output or storage folder.
The input, output and storage folders may be shared but MUST be
located locally, on the same machine as IRISDocument Server.
Otherwise IRISDocument Server will be susceptible to network
errors.
Tip: if, for any reason, you still decide to use network paths*, define
them as UNC paths.
(*) No product support offered in this case.
Provide sufficient disk space.
Chapter 15 – IRISDocument Golden Rules
124
The Watched Folders module uses a lot of temporary files and stores
uncompressed copies of the images for OCRing and document
creation, which may take up to 25MB per page.
IRISDocument stores temporary files both in the IRISDocument
work folder and the Windows temporary area.
Tip: defragment your pc's hard disk once in a while.
Other tips for using the Watched Folders module.
o Avoid selecting superfluous options.
Not only do they slow down the recognition process, they also
increase the risk of OCR errors.
o Limit the number of Watched Folders to 10.
The more Watch Folders you have the more time is needed for
IRISDocument to check for content changes.
o The Watched Folders Tasks must be of reasonable size.
Prefer more tasks to bigger tasks.
o Do not use a single folder as input and output folder.
o Do not use the work folder as input folder.
o Make sure IRISDocument Server does not reboot
automatically, e.g. after automatic Windows updates.
