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.

Interpreting the Test Print

The Color Balance test print contains numbered 
images that indicate possible adjustments that 
can be made. You can choose to make an 
adjustment to the Color Density, the Black 
Density, or the Color Balance.

■

The Black Density Images, numbered 
-3K...0,...+3K, show a lightness/darkness 
range of 30% halftones using black only.

■

The Color Density Images, numbered 
-3CMY...0,...+3CMY, show a 
lightness/darkness range of 30% gray 
halftones using three colors (cyan, magenta, 
yellow).

■

The Color Balance Images, numbered 
0,10,11,...21, show variations of three-color 
gray. Each of these circles contains gray with 
tints of other colors.
