3. The Scanned image
When a document is scanned or opened into Readiris, its image is displayed. The different
recognition zones are displayed. The zones can be edited with the tools in the Image and Layout
Editing panel.
4. The Pages panel
Each page you scan or open in Readiris has its thumbnail displayed in the Pages panel. The pages are
processed top-down. To change the order of the pages, you drag a page from one location to
another.
To have a better overview of the page thumbnails you can switch to Thumbnail view. In this view
only the page thumbnails are displayed. The analyzed image is not displayed anymore. In Thumbnail
view the thumbnails run from left to right, and from top to bottom.
To switch to Thumbnail view, click the Thumbnail view icon at the bottom of the Pages panel.
5. The Image and Layout Editing panel
The Image Editing panel allows to modify the current page: you can deskew pages that were
scanned at an angle, rotate them, adjust the image quality, and so on. Point to the different buttons
to display their tooltips.
Also see the sections Optimizing the Scanned Documents and Editing the Recognition Zones for
more information.
Changing the user interface language
Readiris opens in the user interface language that is currently activated in your Mac System
Preferences.
To change the user interface language in Readiris:
Click the System Preferences icon.
Click the Language & Region icon.
Drag the language of your choice to the top of the list.
The user interface of Readiris is available in a wide range of languages.
Close Readiris and restart the computer to apply the new language settings.

Configuring your scanner in Readiris
Readiris supports all Twain 1.9 compliant scanners, all Image Capture compliant scanners, and
IRIScan 2 and higher scanners.
Most Image Capture scanners are plug and play. Before you can use a Twain scanner, however, its
drivers need to be installed on your Mac.
Twain scanners
Connect your scanner to your Mac and power it on.
Install your scanner's Twain driver.
In general, drivers can be found on the CD-ROM provided with your scanner and on the
website of your scanner manufacturer. They are not provided by I.R.I.S. Note that some
scanner drivers may not work under the latest versions of Mac OS. See the
documentation supplied with your scanner to find out which platforms are supported.
If necessary, contact your scanner manufacturer.
IRIScan Express scanners
Connect your IRIScan Express scanner to your Mac and power it on.
If Readiris is part of your IRIScan product, the driver has been installed during the installation
of Readiris.
If that is not the case, visit our website www.irislink.com/support to download and install the
required driver.
IRISCard Anywhere / IRIScan Anywhere / IRIScan Book scanners
You do not need to install any drivers when using these scanners. They are not Twain driver-based
scanners that can be used from within any application to scan documents. Instead, they are
designed to be used on their own, disconnected from any computer. The documents you scan are
stored in the scanner’s internal memory (or optional SD card / USB flash drive). From there, they can
be loaded directly into Readiris when you connect the scanner or insert the SD card or USB flash
drive into your Mac.
Readiris 15 - User Guide
14
To check if the scanner driver has been installed successfully:
In the Readiris menu, click Preferences.
Click the Scanner tab.
You should see your scanner listed*.
*This is not the case for the IRISCard Anywhere, IRIScan Anywhere and IRIScan Book
scanners.
If your scanner is not listed, its driver has not been installed successfully.
Note that the IRIScan settings at the bottom are only available if an IRIScan Express 2
scanner is connected. Later versions of IRIScan Express function as regular Twain
drivers.
Once the scanner has been configured you can start scanning, using the default scanner
settings.

Section 3: Basic Document Processing
Processing documents with Readiris is fairly straightforward when using a basic configuration. In this
section we discuss which steps to take when doing such a basic configuration. For detailed
information about all the configuration steps, see sections 4 to 10.
Step 1: Scan or Open your images
In order to scan paper documents your scanner must be correctly configured. See the section
Configuring your scanner if necessary.
Click Scan to scan paper documents with your scanner.
A preview window opens and displays your scanner settings. With TWAIN scanners, these
settings differ from one scanner to another.
Select Color and 300 DPI as preferences to obtain optimal results.
Select the Page Analysis Options of your choice:
Page Analysis is selected by default. This option divides your documents into
recognition zones. Without recognition zones, Readiris cannot process your
documents. If you choose to disable this function, you will need to draw recognition
zones manually on your documents.
Readiris can deskew (straighten) documents and rotate them by means of Page
orientation detection.
When your scanner generates black borders around your documents, or when your
documents contain information that is partially cut from the page, Readiris tends to
create recognition zones on the borders of the document, even though they do not
contain any useful content. In such cases it is recommended to use the option
Ignore border zones.
or
Click File to open existing image files.
Select the Page Analysis Options of your choice.
The same Page Analysis Options are available here.

Loading Settings
To load a settings file you saved:
On the Settings menu, click Open Settings.
Browse for the settings file you saved.
Restoring Factory Settings
On the Settings menu, click Restore Factory Settings.

Section 4: Scanning and Opening Documents
General Processing Options
When scanning and opening documents, Readiris applies several general processing options.
To access these options:
On the Readiris menu, click Preferences.
The Preferences window opens on the General tab.
The options you set here are applied as default to all the documents you'll open or scan.
Preprocessing Options.
Smoothen color and grayscale images
This option is activated by default. It 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). Sometimes smoothening is the only way to separate
text from a colored background.
Process as 300 dpi
Select the option 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.
