Interpreting the Color Balance and
Density Adjustment Page.
You use this print to assess and adjust color
balance, color density and black density.
Use the 30% halftones to judge the current
level and decide on a preference.
Look for:
The Color Density and Black Density should
be at approximately the same level. This is
important in order to make the Color
Balance adjustment.
To determine the correct Color Balance
compare the disk in the center of the Color
Balance object marked “CURRENT” with the
gray background. The background is
produced using black only and the circles
are produced using a combination of cyan,
magenta, and yellow. The adjustment
objective is for the “CURRENT” circle to be
the closest gray of any of the circles when
compared to the gray background.
Refer to the adjustment “Adjusting color
density and balance” on page 77.
