Color Adjust - HP Indigo press 3050 User Manual

Color Adjust

The purpose of the color adjust procedure is to adjust the press to guarantee color
repeatability across the run and between runs. The procedure allows you to set the
density of the 100 percent dot and the 50 percent dot without altering the color
reproduction curve.
PIP deterioration is reflected with inaccurate color. Automatic compensation due to PIP
age is an approximate tool because age is not the only cause for PIP deterioration. The
character of images printed and the number of prints per image also influence the rate of
PIP deterioration. The color adjust procedure fine tunes the compensation process for
each PIP.
The color adjust procedure is performed automatically every 8,000 impressions, unless
overridden by the operator.
The color adjust procedure is triggered automatically when you turn the machine on after
a break of several hours and after PIP replacement.
