3. Choose Edit - Fill menu when the Fill dialog appears as seen in
Fig. 9-6-7. Choose the Use : pop-up menu and select 50% Gray ,
Blending Mode : Normal , Opacity 100% , then click OK . The
image is filled with gray.
4. Go back into the Photoshop Color Settings dialog and change the
Gray pop-up menu in the working space area of the dialog from
Gray Gamma 2.2 (the default) to Gray Gamma 1.8 (or to
other dot gain settings). Notice that the Grayscale document you
just made changes its appearance, which is logical as this file is
an untagged document. Go back into the Color Settings dialog
if you dismissed it earlier and toggle the settings from Color
Management Off back to U.S. Prepress and click OK .
5. Select Image-Mode - Assign Profile in Photoshop CS or Edit-
Assign Profile in CS2. The dialog shown in Fig. 9-6-8 will
appear. Make sure the Preview check box is on. If you wish to
assign the currently specified Grayscale working space, which is
dot gain 20%, do so by selecting the middle radio button.
However, for this exercise, click the third radio button and notice
that as you toggle different options in the Profile : pop-up menu,
two changes occur.
First, the preview changes because you are informing
Photoshop exactly what profile description to use for the
preview, and eventually for conversions, of this document.
Fig. 9-6-7 The Fill
command should be
configured as seen here.
Fig. 9-6-8 Select the
Assign Profile command,
select the Profile radio
button and toggle different
Grayscale profiles in the
pop-up menu while
watching the color
appearance and Profile
indicator in the document.
