The dot gain compensation setting is being set

When the ink is transferred to the surface of the paper under pressure, due to the absorption of the paper, the ink spreads around when it penetrates, resulting in an increase in dots and making the entire image darker. Obviously, different dot gains will occur for different quality papers. The stronger the paper absorbency, the larger the dot gain value. Specifically, newsprint is the largest and coated paper is the smallest. The enlargement of the dot formed by the paper performance generally presents an expansive law of enlargement. In the prepress processing process, it is necessary to compensate for the effect of dot gain.

The dot gain value is different for different sizes of dots. Generally, the value of the high-profile and dark-tone network increase is small, and the halftone dot gain value is larger. It is generally recommended that the default settings be better. For example, the default value is 17% for coated paper, about 22% for offset paper, and about 30% for newsprint.
