What to look for
There are three things to look for in examining the test print.
■
The Color Density and the Black Density are a matter of taste. The 30%
halftones can be used to judge the current level and decide on a
preference.
■
The Color Density and Black Density should be at approximately the
same level. This is important in order to make the Color Balance
adjustment.
■
The correct Color Balance is determined by comparing the circle 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.

balance:
