Setting Dot Limits
The Dot Limits Window (see Figure 4–3) is used to control how inks will be out-
put on a press.
The ink control fields are defined as follows:
•
Total Ink: represents the maximum dot percentage the press can accommo-
date and equals the sum of the CMYK ink percentages. This number is gen-
erally between 260% and 340%.
•
GCR/UCR: Undercolor Removal (UCR) and Gray Component Replacement
(GCR) replace CMY inks with Black in the neutral areas to reduce total ink
on the press. GCR/UCR is the percentage of ink replaced, while Start%
defines the Cyan dot percentage at which GCR/UCR begins.
•
Max Black: This field sets the maximum dot percentage for Black. Start%
defines the Cyan dot percentage at which Black begins to be added.
Note:
It is always advisable to consult with your
press operator when adjusting ink controls.
