CHAPTER 1
I
NTRODUCING READIRIS
SAVE TIME, AVOID RETYPING
Congratulations on acquiring Readiris. This software package will
undoubtedly be of great help in recapturing your texts, tables,
graphics, barcodes and handprinted text.
As efficient as computers are, you have to key in your information
first. If you have ever retyped a 15 page report or a large table of
figures, you know how tedious and time-consuming it can be. Use
this state-of-the-art OCR package to automatically convert paper
documents or scanned image files into text searchable and editable
documents that can be archived and shared. Two recognition modes
are available: one ensures maximal speed, the other guarantees
optimal OCR accuracy.
Scan a printed or typed document, indicate the zones you want to
recognize with Readiris - or have the system detect them for you -
execute the character recognition and export the document to your
word processor. Documents composed of many pages are processed
from start to finish in a single effort. A few mouse clicks beat long
hours of work as Readiris converts your paper documents into
editable computer files: it’s up to 40 times faster than manual
retyping.
The wizard smoothly guides you through the settings required to
operate Readiris, allowing you to obtain quick and easy results. Or
use the SmartTasks to speed up the process even more. You can
send the reading results directly to your word processor or
Chapter 1 – Introducing Readiris
4
spreadsheet, archive them as PDF or XPS files, etc. To recognize
faxes and convert PDF documents, drag their image files from
Windows Explorer to the Readiris application window. Or send an
image promptly to Readiris via the context menu.
Readiris recognizes tabular data and recreates them as worksheets
in your spreadsheet software or as table objects inside your word
processor; your numeric data are immediately ready for further
processing.
Readiris is based on the most advanced recognition technologies.
Font-independent text recognition is complemented by self-learning
techniques. The system is able to learn new characters and words
through contextual and linguistic analysis. This means that the OCR
accuracy of the recognition system will improve as it goes along.
Readiris supports up to 128 languages: all American and European
languages are supported, including the Central-European, Baltic and
Cyrillic languages as well as Greek and Turkish. Optionally,
Readiris can read Arabic, Farsi and Hebrew documents and four
Asian languages - Japanese, Simplified and Traditional Chinese and
Korean. Readiris even copes with mixed alphabets: the software
detects “Western” words that occur in Greek, Cyrillic, Arabic,
Hebrew and Asian documents - many untranscribable proper
names, brand names, etc. are written using the Western symbols.
Readiris uses linguistics during the recognition phase, not
afterwards. As a result, Readiris recognizes all kinds of documents
with top accuracy, including low-quality documents, faxes and dot
matrix printouts. It copes beautifully with badly scanned and copied
documents containing too light or dark font shapes. Joined
characters are resolved while fragmented characters, such as dot
matrix symbols, are recomposed.
Besides that, Readiris has an (optional) user verification function.
When activated, the user verification function (“Interactive
learning”) not only flags the characters the recognition system isn't
sure of but also allows to increase the system's accuracy. All
Readiris
TM
Corporate 12 – User Guide

solutions you confirm are memorized, increasing the system speed
and confidence and rendering the system more intelligent as you go
along. This powerful learning tool also allows you to train Readiris
on special characters such as mathematical symbols and dingbats
and to handle distorted fonts.
To increase your productivity further, Readiris not only recognizes
your texts, but can format them for you as well. Various levels of
formatting are available. When you make use of “autoformatting”,
Readiris recreates a facsimile copy of the scanned document: the
word, paragraph and page formatting of the original document are
retained. Similar typefaces are used, the point sizes and type styles
as used in the source document are maintained across the
recognition. The placement of columns, text blocks and graphics
follows your original documents. Readiris can even include the
background photo of a scanned page in the recognized document.
And as Readiris supports grayscale and color scanning effortlessly,
you can recapture any graphics - be they line art, black-and-white
photos or color illustrations. When a document contains tables,
Readiris reorganizes them in real cells and recreates the cell borders
of the original tables.
In other words, Readiris allows you to archive a true copy of your
documents, be it editable and compact text files instead of scanned
images.
Barcodes that occur on a scanned page can also be read, and the
same goes for handprinted text, provided you write well-spaced
“block letters”.
You can even recognize business cards with Readiris: scan your
business cards, recognize them and convert them into an address
database.
The cards’ data is extracted automatically from the image and the
recognition results are assigned to specific database fields. Readiris
extensively uses a knowledge database, thus acquiring the necessary
intelligence to distinguish between first and last names, cities and
Chapter 1 – Introducing Readiris
6
states, telephone and fax numbers, etc. The resulting data can be
sent directly to your contact management software such as
Microsoft Outlook (Express) or any vCard compliant application.
Readiris is Twain compliant and supports a wide range of flatbed
and sheetfed scanners, “all-in-one” devices or “MFPs”
(“multifunctional peripherals”) and digital cameras. Interval
scanning allows you to scan multipage documents efficiently when
your scanner is not equipped with a document feeder.
Readiris also supports high-speed scanners and executes batch OCR
on large image collections: blank pages can be used to segment
scanned batches into separate documents, automatic barcode
reading ensures the proper indexing of the recognized documents.

digital camera images.
Tips for using a digital camera as scan source:
Calibrate the camera by photographing a white document.
Always select the highest image resolution.
Enable the macro mode of the camera to take close-ups.
Only use optical zoom, not digital zoom.
Hold the camera directly above the document. Avoid
photographing the document at an angle.
Produce stable images. Use a tripod if necessary.
Disable the flash when capturing glossy paper.
Avoid opening compressed camera images.
Adapt the Readiris brightness and contrast settings to the
environment (day light, lamp light, neon light).
Select color or grayscale as color mode.
Processing as 300 dpi
Select Process as 300 dpi when you are processing images of an
incorrect or unknown resolution. The images will be processed as
if they had a 300 dpi resolution.
The resolution of digital camera images is nearly always unknown.

DJUSTING SCANNED DOCUMENTS
When opening or scanning extremely light or extremely dark
grayscale and color images, it may be necessary to adjust those
images before executing the recognition, in order to obtain
satisfactory OCR results.
To adjust images:
Open or scan a color-grayscale document.
Make sure that the scanner settings are correct.
Important: the scanner settings and adjustment settings appear to
be the same but note that both sets of settings are applied at different
stages in the scan/recognition process.
On the Process menu, click Adjust image.
Readiris uses intelligent binarization routines to convert color-
grayscale images into black-and-white images, which are used to
perform OCR on.
Chapter 6 – Adjusting scanned documents
38
o Select Smoothen color image to even out the image.
This option renders grayscale and color images more homogeneous
by smoothening out differences in intensity. As a result, a stronger
contrast is created between the foreground (text) and background
(artwork).
Note: sometimes smoothening is the only way to separate text from a
colored background.
(Original image)
(Binarized black-and-white image)

apply Page Analysis to split up the documents in different
windows.
The Page Analysis option is selected by default. Click the Options
button and disable Page Analysis should you want to avoid automatic
page analysis.
The page analysis results can be modified manually after automatic
page analysis. For more information, see the section Windowing
documents manually.
Window types
Readiris uses five window types: text blocks, graphic zones,
tables, barcode zones and handprinted zones.
Chapter 8 – Windowing documents
46
Page analysis detects text, graphic and table zones automatically.
Barcode zones and handprinted zones need to be drawn manually.
For more information, see the section Windowing documents
manually.
Each window type has its own color code: text windows are orange,
graphics are purple and table windows pink. Barcode zones are
green and handprinted zones blue.
The windows are sorted top-down, left to right. Numbers indicate
the sort order of the windows. The sort order and window types can
be changed, however. For more information, see the section
Windowing documents manually.
Ignore text zones on page borders
When your scanner generates black borders around the actual
image, page analysis tends to find zones where there’s only noise.
To avoid this, click Do Not Detect Windows on Borders on the
Settings menu and scan the document again.
Ignore exterior zone
As an alternative to windowing documents automatically, the
function Ignore exterior zone can be used. This function is useful
when only one particular area on the document pages needs to be
OCRed.
Select Ignore exterior zone by clicking the corresponding button
on the image toolbar.
Draw a frame around the part of the page you want Readiris to
recognize.

CHAPTER 10
R
ECOGNIZING DOCUMENTS
INTRODUCTION
To recognize documents, Readiris applies linguistics during the
recognition phase. As a result, Readiris recognizes text, tables,
graphics, barcodes and handprinted text in all kinds of documents.
Readiris even copes with complex columnized documents, low-
quality documents, faxes, dot matrix printouts, badly scanned and
copied documents containing too light or dark font shapes, etc.
Readiris supports 128 languages: all American and European
languages are supported, including the Central-European, Baltic and
Cyrillic languages as well as Greek and Turkish. Optionally,
Readiris can read Arabic, Farsi and Hebrew documents and four
Asian languages - Japanese, Simplified and Traditional Chinese and
Korean. Readiris even copes with mixed alphabets: the software
detects “Western” words that occur in Greek, Cyrillic, Arabic,
Hebrew and Asian documents - many untranscribable proper
names, brand names etc. are written using the Western symbols.
Readiris is based on the most advanced recognition technologies.
Font-independent text recognition is complemented by self-learning
techniques. The system is able to learn new characters and words
through contextual and linguistic analysis. This means that the OCR
accuracy of the recognition system will improve as it goes along.
Besides that, Readiris has an (optional) user verification function.
When activated, the user verification function (Interactive learning)
not only flags characters the recognition system isn't sure of but also
Chapter 10 – Recognizing documents
58
allows to increase the system's accuracy. All solutions you confirm
are memorized temporarily during recognition, increasing the
system speed and confidence and rendering the system more
intelligent as you go along. This powerful learning tool also allows
you to train Readiris on special characters such as mathematical
symbols and dingbats and to handle distorted fonts.
The interactive learning results can also be stored permanently in
font dictionaries for future use.
Another way to boost the recognition accuracy is to use user
lexicons. You can create customized user lexicons containing
specific terminology you want Readiris to recognize.
SELECTING THE DOCUMENT LANGUAGE
Readiris offers OCR in 128 languages. Readiris supports all
American and European languages including the Central-European,
Cyrillic and Baltic languages, as well as Greek and Turkish.
Readiris Pro Asian and Readiris Corporate Asian additionally
recognize documents in Japanese, Simplified Chinese, Traditional
Chinese and Korean.
Readiris Pro Middle-East and Readiris Corporate Middle-East
additionally recognize documents in Arabic, Farsi and Hebrew.
In order for Readiris to recognize a document, the document
language must be specified.
To do so:
Click the globe button on the main toolbar and select the language
of your choice in the drop-down list.
Readiris
TM
Corporate 12 – User Guide
59
The 5 most recently selected languages are moved to the top of the
language list.
Important: select the document language before executing page
analysis when you are dealing with Asian, Hebrew and Arabic
documents. Specific page analysis routines are used for these
documents.
The recognition can also be limited to a numeric character set to
optimally recognize tables and figures. Readiris then only recognizes
the numerals 0-9 and the following series of symbols:
To activate numeric mode, select Numeric in the Language dialog
box.
Chapter 10 – Recognizing documents
60
Recognizing documents with mixed languages
Readiris also allows you to enable mixed character sets. That way
Readiris switches languages in the middle of a sentence
automatically and recognizes English words (proper names etc.)
that occur in "exotic" languages.
Click the globe button on the main toolbar and select the required
language combination in the language drop-down list.
Note: when processing Asian or Hebrew documents, mixed
characters sets are used automatically.
Recognizing secondary languages
Next to the primary language or language combination, Readiris
allows you to select up to 4 secondary languages of the same
language group.
This is useful when recognizing multilingual documents.
Note: 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.
When scanning Arabic documents, only English is available as
secondary language.
Speed-Accuracy
Select the right trade-off between OCR speed and OCR accuracy.
This trade-off is available for the Latin, Cyrillic and Greek alphabets.
Readiris
TM
Corporate 12 – User Guide
61
Tip: favor accuracy over speed when the image quality is rather poor.
USING USER LEXICONS
During recognition, Readiris is assisted by linguistic databases to
recognize text correctly. These linguistic databases are standard
lexicons and are available for every supported language.
As powerful as these standard lexicons may be, the recognition
accuracy can still be boosted by using customized user lexicons. By
means of user lexicons, Readiris can recognize technical, scientific,
legal and company-specific terminology it would otherwise have
difficulty with.
To create and use a user lexicon:
On the Settings menu, click Edit User Lexicon.
You can also access the User Lexicon Editor via the Windows
Programs menu.
Chapter 10 – Recognizing documents
62
Insert the words you want Readiris to recognize and click the
Add button.
You can also copy-paste text segments from other files and import and
edit existing text files.
Tip: importing company documents or word list may be the fastest
way to create a user lexicon containing company-specific
terminology.
The terms you enter are sorted alphabetically.
Duplicate words are rejected automatically.
Click Save to save the .txt file in the folder of your choice.
Return to the Settings menu and point to User Lexicon.
Click the Use File command and select the user lexicon file of
your choice in the dialog box.
Click the Open button to open the user lexicon.
Note that in order for Readiris to recognize the words in the user
lexicon, the correct language must have been selected. Click the globe
icon on the main toolbar to do so.
Words containing characters that do not exist in the selected language
will not be recognized correctly.
Click Recognize + Save to start the recognition.
Syntax rules
Several syntax rules apply when inserting terminology:
Case differences are maintained.
E.g. IRISCard stays IRISCard
Readiris
TM
Corporate 12 – User Guide
63
All punctuation symbols and special characters at the
beginning and end of words are filtered automatically.
Hyphens inside words are maintained.
E.g. Notre-Dame-de-Paris stays Notre-Dame-de-Paris
Tip: watch out for hyphenation at the end of a line when you import
text files or copy-paste words that cover two lines.
Numbers are rejected. Digits, however, can occur inside product
names and are included.
E.g. FAT32 stays FAT32
Systolic 150 will become Systolic
DEFINING THE DOCUMENT CHARACTERISTICS
Next to the document language, other document characteristics such
as the Font type and Character pitch play an important role in the
recognition process.
Font type
Readiris 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 required to
recognize dot matrix documents and need to be activated.
Chapter 10 – Recognizing documents
64
To select the font type:
On the Settings menu, point to Font type.
The font type is set to Automatic by default.
That way, Readiris recognizes "25 pin" or "NLQ" (Near Letter
Quality) dot matrix, or other "normal" printing.
To recognize only dot matrix printed documents, click Dot
matrix.
Readiris will recognize so-called "draft" or "9 pin" dot matrix printed
documents.
Character pitch
The character pitch is the number of characters per inch in a
typeface. The character pitch can either be fixed, in which case all
characters have the same width, or proportional, in which case the
characters have a different width.
To select the character pitch:
On the Settings menu, point to Character Pitch.
The character pitch is set to Automatic by default.
Click Fixed if all characters of the typeface have the same width.
This is often the case in old typewriter documents.
Click Proportional if the characters of the typeface have a
different width. Virtually all fonts in newspapers, magazines and
books are proportional.
Readiris
TM
Corporate 12 – User Guide
65
Important: these document characteristics do not apply to Asian,
Hebrew or Arabic documents.
USING INTERACTIVE LEARNING
Readiris offers an interactive learning function. By means of
Interactive learning you can train the recognition system on fonts
and character shapes, and correct the OCR results if necessary.
During interactive learning, any characters the recognition system
isn't sure of are displayed in a preview window, in combination with
their parent word and the proposed solution.
Interactive learning can substantially enhance the accuracy of the
recognition system and is particularly useful when recognizing
distorted, defaced forms. Interactive learning can also be used to
train Readiris on special symbols it is unable to recognize initially,
such as mathematical and scientific symbols and dingbats.
To enable interactive learning:
On the Learn menu, click Interactive Learning.
Define the necessary settings and click the Recognize + Save
button to recognize the document.
At the end of the recognition, Readiris enters the interactive
learning phase.
The characters the recognition system isn't sure of are displayed.
Chapter 10 – Recognizing documents
66
If the results are correct:
o Click the Learn button to save the result as sure.
The learning results are temporarily stored in the computer memory,
for the duration of the recognition. Readiris will no longer display
the learned characters when OCRing the rest of the document.
When a new document is OCRed, the learning results are erased.
To save learning results permanently, use a font dictionary. For
more information, see the section Using font dictionaries.
o Click Finish to save all solutions the software offers.
If the results are incorrect:
o Type in the correct characters and click the Learn button.
or
o Click Don't learn to save the result as unsure.
Use this command for damaged characters which could be confused
with other characters if learned. E.g. the number 1 and the letter I,
which have an identical form in many fonts.
o Click Delete to delete characters from the output.

Use this button to prevent document noise from appearing in the
output file.
o Click Undo to correct mistakes.
Readiris keeps track of the last 32 operations.
o Click Abort to abort interactive learning.
All learning results will be deleted. Next time you click Recognize
+ Save, interactive learning will start again.
USING FONT DICTIONARIES
When scanning many documents of the same type, font quality and
printing quality, you may not want to repeat the learning process
every time. Therefore, it is useful to use font dictionaries. Font
dictionaries contain font information learned during interactive
learning and can substantially increase the recognition results.
Note that font dictionaries are limited to 500 shapes. You are
recommended to create separate dictionaries for specific
applications.
To create a new font dictionary:
On the Learn menu click the command New Font Dictionary.
Readiris will open the dictionary Readiris.dus by default. Change the
file name and click Save to save it as a new dictionary.
Click Interactive Learning on the Learn menu to activate it.
Click Recognize + Save to recognize the document.
Readiris enters the interactive learning phase. Use the buttons of
the dialog box to save characters in the font dictionary.
Chapter 10 – Recognizing documents
68
To use an existing font dictionary:
On the Learn menu click Font Dictionary.
Select the dictionary you want to use and click Open.
On the Learn menu click either Append Font Dictionary or
Read Font Dictionary.
When selecting Append Font Dictionary, make sure to enable
Interactive Learning. Readiris will recognize the character shapes
stored in the dictionary and use interactive learning, allowing you to
store new information in the dictionary.
When selecting Read Font Dictionary, Readiris will recognize the
character shapes stored in the dictionary but will not add new content
to the dictionary, even if Interactive Learning is enabled. Note that it
is still useful to use Interactive Learning to check, and if necessary,
correct the recognition results which are not saved in the font
dictionary.
Caution: do not click Font Dictionary on the Learn menu and open
an existing dictionary while the dictionary mode New Dictionary is
enabled. Otherwise, the contents of the existing font dictionary will be
erased.

o The option Use columns instead of frames creates
columnized documents.
Columnized texts are easier to edit than documents containing
multiple 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.
o The option Insert column breaks inserts a hard column
break 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.
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.
o The option Add image as page background places the
scanned image as page background beneath the recognized

Several rules must be taken into account in order for Readiris to
recognize handprinting:
Write regular, well-spaced characters.
Note how the characters A, G and Q are written.
Readiris
TM
Corporate 12 – User Guide
111
Use a sufficiently thick ballpoint.
Black pens yield better results than blue pens.
Do not use pencils.
Don't stylize too much.
Excessively stylized characters increase the risk of OCR errors.
Don't open loops which should be closed, don't close loops
which should be open.
Avoid broken characters.
Avoid retracing.
Retracing reduces the image quality and clarity of handprinted
symbols.
Characters that are entirely stricken out will not be recognized.
Write ones correctly.
The number 1 can be written in the "anglicized" and "European" style.
Ones can be underlined or not.
Chapter 16 – Recognizing handprinted text
112
The horizontal underlining bar does not have to touch the rest of the
font form.
Tip: when less than optimal results are obtained, use the I.R.I.S. writing
form and adapt your writing style. The blank I.R.I.S. writing form serves as a
full-page template on which block letters can be filled out correctly and in the
right size. The form can be found on the Readiris CD-ROM and in the
Readiris installation folder.

ECOGNIZING BARCODES
INTRODUCING BARCODE READING
Next to optical character recognition of 128 languages, Readiris
also offers barcode reading. Barcodes can either be recognized
manually or automatically when they are used for indexing
purposes.
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-8, Interleaved 2 of
5, MSI Pharmaceutical, MSI-Plessey, Kodak patch code, PDF-417,
PostNet, UCC-128, UPC-A and UPC-E.
Note that laser printed and inkjet printed barcodes are required in
order for Readiris to perform OCR. Matrix printed barcodes are not
supported as they do not produce sufficient contrast and their
resolution is mostly limited to 60 dpi.
Manual barcode reading
Determine which barcodes you want Readiris to recognize:
Chapter 17 – Recognizing barcodes
114
On the Settings menu, click Barcodes.

around the barcodes zones in the document.
Click Recognize + Save on the main toolbar.
The entire document including the barcode content will be recognized.
Note: right-click a barcode zone and click Copy as Data to copy its
content to the clipboard.
Automatic barcode reading

document batch. Readiris can automatically look for barcode pages
and mark them as cover page, indicating the beginning of a new
document.
Determine which barcodes you want Readiris to recognize:
o On the Settings menu, click Barcodes.
o Select the symbologies you want Readiris to recognize.
o Decide whether you want Readiris to verify or remove the
check digits.
Click the Document Type button on the main toolbar and click

ECOGNIZING BUSINESS CARDS
INTRODUCING BUSINESS CARD READING
Next to recognition of "regular" documents, Readiris Corporate also
offers business card recognition.
Readiris allows you to scan business cards, recognize them and
convert them into an address database. By means of OCR (Optical
Character Recognition) the data on business cards is extracted
automatically from the image, converted into editable text and
inserted in the correct database field through field analysis. This
works for 28 countries.
Readiris not only analyzes but also formats the recognized text. The
resulting data can be used in many ways: send contacts to Microsoft
Outlook, Microsoft Outlook Express, Lotus Notes and Palm
Desktop or save them in a structured file e.g. in the vCard format, to
export them to any address database.
Dedicated IRIS business card scanners are available for Readiris.
Contact I.R.I.S. for more information on the IRISCard business
card scanners.
To recognize business cards:
Click the Document Type button and click Business cards or
Multiple Business Cards in a Single Scan.
Chapter 18 – Recognizing business cards
118
Select the latter option when using a flatbed scanner. Note that the
background must be black in order for Readiris to extract the various
business cards. To create a black background, scan cards with the
scanner lid open.
When you have forgotten to select Multiple Business Cards in a
Single Scan as document type, click the command Extract Business
Cards on the Process menu. The various business cards will be
extracted from the scanned image.
When scanning business cards, first click the Scanner button to
make sure the scanner settings are correct.
Tip: select a scanning resolution of 400 to 500 dpi to recognize
business cards successfully.
The necessary options are enabled by default: Readiris applies
Page Deskewing, Automatic Rotation and Page Analysis
automatically.
Click the Options button should you want to change the settings.
Click the Open button to open a scanned business card.
Or click the Scan button to scan a paper business card.
When you are using the IRISCard pro, the following dialog box will
open. Select the correct paper size, resolution and image type.
Readiris
TM
Corporate 12 – User Guide
119
Click Calibrate when using the scanner for the first time and insert
the calibration sheet.
Select the correct paper size, resolution and image type.
Click the Scan button in the dialog box to scan the business card.
Readiris will display the analyzed business card.
Change the windows types, if necessary: right-click the window you
want to change, point to Window then to Type. Then click the correct
window type.
Click the globe button to select the correct card style.
Chapter 18 – Recognizing business cards
120
It is recommended to sort your business cards by country, as you can
only activate one card style at a time.
Click the Format button to select the output format.
Business cards can be saved in the vCard, HTML and comma
delimited text format or be sent to Microsoft Outlook, Microsoft
Outlook Express, Lotus Notes and Palm Desktop.
Click Recognize + Save to recognize the business card(s) and
export them.
The Interactive Learning option is also available for business card
reading. For more information, see the section Using interactive
learning.
