What To Look For
There are basically three things to look for in examining the test print.
1. 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.
2. The Color Density and Black Density should be at approximately
the same level. This is important in order to make the Color Balance
adjustment.
3. 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 objective is for the “CURRENT” circle to be the closest
gray when compared to the background of any of the circles in the
object, i.e., the most neutral.
