What to look for There are three things to look for in examining the test print. s 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. s The Color Density and Black Density should be at approximately the same level. This is important in order to make the Color Balance adjustment. s 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. Making adjustments Use the following procedures to make adjustments to the color density and balance: Black density adjustment 1. Press Item (2, 6) keys until you see Color Adjust Menu: Black Density. 2. Press Value (3, 7) keys until you see Black Density = New Value. Values are: -3K, -2K, -1K, 0, +1K, +2K, +3K. 3. Press Enter. The Color Adjust Page prints and the front panel displays Color Adjust Menu: Black Density. Repeat Steps 2 and 3 above until you are satisfied with the results. Color density adjustment 1.
