摘要:
An image forming apparatus having therein an image forming device that transfers an image onto a transfer sheet and a reversing device that reverses the transfer sheet, wherein the image forming device transfers an image on the front surface of the transfer sheet, then, the reversing device reverses the sheet, and the image forming device transfers an image onto the rear surface of the sheet and the image forming apparatus further has therein a correcting device that corrects the overall skew of the transfer sheet depending on an inclination of a leading side of a transfer sheet in the conveyance direction set in advance before an image is formed on the front surface, and corrects the overall skew of the transfer sheet depending on an inclination of a leading side of a transfer sheet in the conveyance direction set in advance before an image is formed on the rear surface.

The invention relates to a device and method for printing a recording medium consisting in fixing the recording medium in a fixing device after application of a first toner image, wherein said recording medium shrinks along at least one main axis. Afterwards, the recording medium is printed with a second toner image during a second printing process. During generation of a bitmap (110, 116) for producing a latent image for the first printing process, the pixel number taken into consideration during printing is modified according to the expected shrinkage in the direction of the main axis.

摘要:
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Einstellung des Registers bei einer Mehrfarbendruckmaschine (1) mit mehreren Einrichtungen (2,2',...) zur digitalen Erzeugung von Teilfarbenbildern (3,3',...), wobei die Druckergebnisse erfaßt und zu einer derartigen Steuerung der Erzeugung der Teilfarbenbilder (3,3',...) herangezogen werden, daß registerhaltige Drucke erzielt werden, und wobei eine Veränderung der Abmessungen der Drucksubstrate (4) durch den Druck ermittelt wird, um diese Veränderung für eine erneute Bedruckung zu berücksichtigen. Das genannte Verfahren und die genannte Vorrichtung sollen derart ausgestaltet werden, daß eine Deckungsgleichheit von Schön- und Widerdruck erzielbar ist. Erfindungsgemäß wird dies dadurch erreicht, daß die Veränderungen der Abmessungen des Schöndrucks (6) von der Übertragung auf das Drucksubstrat (4) bis zur Fertigstellung des Schöndrucks (6) ermittelt und dazu herangezogen werden, die digitale Erzeugung der Teilfarbenbilder (3,3',...) für den Widerdruck (5) derart zu steuern, daß er nach dem Druck deckungsgleich mit dem Schöndruck (6) ist.
