Abstract

Um eine Druckform mittels eines Thermotransfermaterials reversibel so zu bebildern, daß eine hohe Auflage mit gleichbleibender Druckqualität sichergestellt wird, ohne die Schichtdicke des Thermotransfermaterials entprechend der gewünschten Auflage anpassen zu müssen, wird ein Verfahren unter Verwendung einer Transferfolie vorgeschlagen, bei dem in einem ersten Schritt eine Bebilderung der Druckform durch punktuelle Ansteuerung und Übertragung der Beschichtung der Transferfolie vorgenommen wird, daraufhin die Transferfolie zwischen der Druckform und der Bildinformation-Übertragungseinheit entfernt wird und in einem zweiten Schritt eine zweite identisch mit der im ersten Schritt bildmäßig gesteuerte Erwärmung der Oberfläche der Druckform vorgenommen wird, so daß die im ernten Schritt übertragenen Bildpunkte auf der Druckform nochmals erwärmt und fixiert werden.In order to reversibly print form using a thermal transfer material illustrate that a high circulation with constant print quality is guaranteed is, without the layer thickness of the thermal transfer material according to the Having to adjust the desired edition is a procedure using proposed a transfer film, in which in a first step Illustration of the printing form by selective control and transmission of the Coating of the transfer film is carried out, then the transfer film between the printing form and the image information transmission unit is removed and in a second step a second identical to that in the first step imagewise controlled heating of the surface of the printing form is so that the pixels transferred in the harvesting step on the printing form be warmed up and fixed again.
