5-8 PowerColor User Guide
The Dot Gain table shows dot percentages in increments of 5% with editable fields
to set the gain at those percentages in each of the four color channels. Dot per-
centages are determined by the dot gain value a particular press experiences. This
value is best determined in consultation with your press operator. The Dot Gain
table fields function as follows:
• Density: defines the maximum density for each ink.
• Position: defines the dot percentage at which the press experiences maxi-
mum dot gain.
• Gain: sets the amount of dot gain at the dot percentage indicated under
Position.
Note: For greater ease of customization, you
can enter precise values in any of the fields.
After entering values in the Position and Gain fields, the Dot Gain table adjusts to
reflect these values, ramping down on both sides of the Position percentage. To
understand how to use PowerColor’s Dot Gain feature, see the example below:
