Screen angle

Because each halftone screen consists of a regular pattern of shapes, it creates a pattern on the printed image. When the separations are combined, the patterns created by each separate halftone screen interact. This interaction can create an undesirable effect, called a moiré pattern.

In most cases, moiré patterns can be avoided by using the default settings. However, Pantone colors and duotones, made up of spot colors and combined with other inks, may cause printing problems. Consult your service bureau for further consultation.

When you print color separations, the screen angles are set automatically. If you change these settings incorrectly, the print job may not print properly.
