Setting Gray Balance values
Note
Use
Gray Balance with 3-Color and 4-Color Transfer Rolls;
adjusting
Gray Balance values has no affect if you have a Black
Transfer Roll installed.
Use the Gray Balance dialog box to do the following:
■
Adjust a transfer roll’s printed colors to produce a neutral gray, by
independently adjusting cyan, magenta, and yellow so the three
primary colors produce equal densities or amounts of color.

■
The CMY (cyan, magenta, and yellow) color panels on a transfer
roll can each print different densities, or amounts of color. A
composite or neutral gray made from printing equal amounts of
CMY can show a color shift if one or more of the colors is printing
with a different density from the other colors. For example, if the
cyan panel on a transfer roll is printing lighter than normal, then a
neutral gray appears more red (combination of magenta and
yellow). You can adjust the printer to print cyan darker than
normal to even out the relative densities between the three colors
by adjusting the gray balance at different points along the
CMY/gray scale print density range of the printer.
