摘要：The invention relates to a process for screenprinting one or more colours of inkon a substrate. A halftone pattern is provided on a screen for each colour of ink, and theink is forced through the screen provided with the halftone pattern and onto the
substrate. The diagonal screen orientation of the screen and the orientation of thehalftone pattern include an angle of +30° or -30°. The best value for the number of linesper centimetre of the pattern equals (Z/n) x cos 30° or Z/2 x (1/n + 1/n+1) x cos 30°,wherein Z is the number of wires per centimetre of the screen and n is an integer. Agroup of screens for use with this screenprinting process comprises two types of screens,with the diagonal screen orientations of the screens of the two different types includingan angle of 30°.
