Abstract

An arrangement for printing flat workpieces is provided and includes an application roller which rolls on the workpiece surface 6 to be printed and thereby applies a printed image to the workpiece surface 8, the application roller forming a printing cylinder 5 or a transfer roller 1 cooperating with a printing cylinder 5, a counter-roller 2 which forms in cooperation with the application roller a printing gap 3, through which the workpiece 4 passes during the printing process, and a transport device 7 for feeding the workpiece 4 into and out of the printing gap 3 formed by the application roller and the counter-roller 2. A detector device 8 is present in the direction of transport of the workpiece 4, before the printing gap 3, for detecting the position of a workpiece front end 9 or an image beginning mark, and cooperates with the transport device 7, 11 and/or the printing cylinder 5; wherein the transport of the workpiece 4, prior to reaching the printing gap 3, is accelerated or delayed and/or the angular position of the printing cylinder 5 can be changed by accelerating or delaying its rotational motion in order to bring into agreement the beginning of the printed image with the…
