frequency-modulated (FM) screening

A method of creating halftones where the spots are all the same size, but the frequency or number of dots changes in a given area. There are more dots in a dark area and fewer in a light area.

frozen job

A job for which the appropriate paper stock is not available: for example, the correct paper type, size, or weight.

gravure printing

A printing method in which the image is engraved through a screen below the surface of a cylinder. The ink is transferred to paper when pressed to the cylinder. Gravure is used for very long print runs and on many substrates.

gray balance

The values for yellow, magenta, and cyan that produce a neutral gray with no dominant hue when printed at a normal density.

gray component

The amounts of CMY in a color which result in neutral gray, based on the lowest separation value of the color.

gray component replacement (GCR)

A method for reducing the CMY amounts that produce the gray component in a color, without changing the color hue.
