Abstract

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Registereinstellung mit einer Erfassung des Eintritts eines Drucksubstrats (2) in eine Druckmaschine (1) und einer Berechnung des Beginns der digitalen Erzeugung von Teilfarbenbildern (3, 3', 3", 3"') für die Erzielung einer registerhaltigen Lage der Teilfarbendrucke (4, 4', 4", 4"') auf einem Drucksubstrat (2).
Durch die Erfindung soll das Verfahren und die Vorrichtung derart weitergebildet werden, daß mehr Zeit zur Berechnung der Einstellwerte für die Registereinstellung zur Verfügung steht. Dies wird dadurch erreicht, daß das Drucksubstrat (2) vor seinem Eintritt in die Druckmaschine (1) erfaßt wird und nach dieser Erfassung die Berechnung der Relativlagen der Teilfarbenbilder (3, 3', 3", 3"') erfolgt und daß mit dem Eintritt in die Druckmaschine (1) eine genaue Erfassung der Vorderkante (5) des Drucksubstrats (2) vorgenommen wird und zur Grundlage für die Bestimmung der Starts der bezüglich ihrer Relativlage vorberechneten Erzeugung der Teilfarbenbilder (3, 3', 3", 3"') gemacht wird.
