Zwischent\u00f6ne wie im Digitaldruck gibt es nicht. Um Grauwerte, Abstufungen und Zwischent\u00f6ne zu erhalten, k\u00f6nnen Motive digital gerastert werden. Diese Umwandlung nennt man Halbtonrasterung. Dieser Vorgang verwandelt jede Helligkeitsinformation des Motivs in kleinere oder gr\u00f6ssere schwarze Punkte.<\/h4>\n\n\n\n<h4 class=\"wp-block-heading\">Mit dem Halbtonraster k\u00f6nnen Fotos f\u00fcr einen Vierfarbendruck in CMYK umgewandelt werden. Mit diesen vier Farbebenen werden die Vorlagen f\u00fcr den Siebdruck hergestellt.<\/h4>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n\n\n\n<h4
