1 Introduction

Every color input or output device has its own gamut, i.e.

the range of colors they can produce. A successful artwork for

print or for online use relies on accurate color reproduction.
ScanWizard Pro provides complete color management solution for
scanning to let you achieve color consistency for your application.

To reproduce color accurately, you will have to setup your
color management system properly depending on the operating
system and the applications you’re using. It is not difficult process
but a bit tedious. You’ll need to consult their documentation for
more information.

ScanWizard™ Pro for Macintosh provides complete
scanning color management solution by being compatible with
common profile standards put by forth by the InterColor
Consortium (ICC), an association of major software developers.

ScanWizard Pro for Macintosh allows you to:

Ø Profile your scanner and create various scanner ICC profiles
Ø Select and apply scanner profiles to scan jobs
Ø Specify destination RGB and CMYK profile

Ø Support soft proof by compensating destination profile

with monitor display

Ø Embed ICC profile to scanned images
Ø Deliver uncorrected “raw” image data

with ScanWizard Pro entirely. Or you may scan and then process
image with your favorite applications.

Macintosh color management features and workflow in detail. You
will learn how all these features works together and how you can
take advantage of them.

2 Calibrating Your Monitor

profile is the first step to achieve high color consistence and
precision of color management. This will ensure the closest
possible match between your colors on-screen and those produced
by a scanner, a printer, a video display, or a different computer
monitor, and also between your colors in ScanWizard Pro and
other programs such as Adobe Photoshop™ 5.

With all these features, you may manage color by working

Monitor ICC profiles may be created specifically by using
either one of the following utilities:

Ø The Calibration function of the Monitor Control Panel for

ColorSync 2.5 or later.

Ø Adobe Gamma utility, from Adobe Photoshop 5.0 or later.
Ø Any third-party monitor calibration programs or hardware

calibrator

You can also obtain your monitor profile by checking with
the manufacturer of your monitor.

3 Selecting Display (or System) Profile

After creating or identifying the proper monitor profile,
you need to select the display profile to make sure the images will
be displayed consistently on the monitor.

It is strongly suggested to always update your Apple
ColorSync system software to the most up-to-date version. If you
have ColorSync earlier than version 2.5, please update it to the
most recent version available.

To select the display profile, bring up the Monitor control
panel. An example is shown below:

Figure 1. Mac OS Monitor Control Panel

After selecting your monitor profile, you may verify the
selection in the ColorSync control panel, as shown in the example
below.

The Display profile is the only setting that ScanWizard Pro
will be using in the ColorSync control panel. You should not
change the display profile in the middle of running ScanWizard
Pro, which recognizes the profile during its start up time.
Whenever you change the display profile, your must restart
ScanWizard Pro.

If you have more than one monitor, each monitor has its
own display profile selection. However, ScanWizard Pro only
works with the main display, where the menu bar is displayed. In
this case, do not move the Preview Window to any secondary
monitor. Otherwise, the colors will be not correctly displayed.

4 ScanWizard™ Pro Color Management

ScanWizard Pro delivers full set of color management
function to give you the best possible image quality as well as
maximum flexibility. You don’t need other 3rd party utilities or
program to get satisfactory results. ScanWizard Pro package

process to your favorite applications. It is totally up to you.

The color management functions are accessible from a few
various places, discussed in the following sections.

1.0 Microtek Scanner Profiler

The color space of a scanned image is "described" by a
scanner profile, i.e. a scanner profile is used as the "source"
profile in the color matching process. Every Microtek scanner

comes with a set of default 16-bit resolution look up table

scanner profile.

Microtek Scanner Profiler uses Kodak’s color management
engine to characterize scanner. Unlike many third party scanner
profilers, scanner profiles created by Microtek Scanner Profiler
contains additional private tags, which contain proprietary
information to allow ScanWizard Pro to deliver more accurate
color rendering and detail tonal range reproduction.

The default profile is the best settings from manufacturer.
You may use default scanner profile. Also, you may create your
own scanner profile by using Microtek Scanner Profiler, or known
as MSP. Profile your scanner regularly guarantees accurate color
consistency for your scanner. Please refer to the MSP user’s guide
for recommended profiling period.

create various scanner profiles of different settings for your needs.
Make sure you specify a clear description because most
applications ask you to select a profile by descriptions, not by
filename.

1.2 Color Matching Setup Dialog Box

When ScanWizard Pro is started for the very first time, the
Color Matching Setup dialog box is displayed to ask you setup your
color management parameters; unlike scanner profile discussed
earlier, these parameters are applied to all scan jobs. You may also
access the dialog box afterward by running Preferences | Color

Matching Setup command.
