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.    
Adjust for neutral gray to help fine-tune printer colors if you see a 
hue shift in your prints.          
Specify the neutral grays for each gray level.
