Microtek 1000xl Reference Manual

White/Black Points Setup

This command provides you with advanced controls for setting the clipping
points for your white and black points, as well as determining the output levels
for the white/black points on your printer.

To use this feature:

1.

Choose the White/Black Points Setup command from the Preferences
menu.

2.

As an alternative, you can click this command from the Color Correction
Menu. This is also the same thing as clicking the White/Black points tool in
the Settings window and then clicking the Setup button from the dialog box
that comes up. When the dialog box comes up, specify your preferences.

A. Auto Clipping

The Auto White Point clipping and Auto Black Point clipping fields allow you to
specify the percentage by which the white and black points, respectively, can be
clipped from the histogram. The clipping is done after you click the Auto button
in the White/Black Points dialog box.

For example, if you specify 10 percent as your White Point clipping value and
then click the Auto button, the white point on the histogram is adjusted so that
10 percent of the color information is "clipped" or ignored. The resulting 90
percent information leftover is then remapped, resulting in an image with less
highlight detail.

The same principle above applies to the
Auto Black Point clipping feature, which
governs the black point for shadows.

These fields are normally used by more
advanced users, and the features are taken
care of automatically if you have set up
Color Matching correctly early on in
ScanWizard Pro.
