Color Management Guide

Pre-Calibration
Engine Density
Adjustment

This chapter discusses how to set the color densities of Yellow, Magenta, Cyan and Black (Y/M/
C/K) to within optimal parameters for color calibration.

This procedure should be performed as desired, but especially:

•

After changing the Developer of a color

•

After using approximately one roll of paper since the Developer of a color was changed

•

When the highest level of image quality is required
