Patent ID: 7127992

Claim:
Arrangement for printing flat workpieces ( 4 ) comprising: 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 including at least one of a printing cylinder ( 5 ) and 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; including a first drive connected to at least one of the application roller and the counter-roller which is controllable for producing or eliminating slippage between the application roller and the workpiece ( 4 ); 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 ); and a detection device ( 8 ) that detects a position of a workpiece front end ( 9 ) or an image beginning mark located before the printing gap ( 3 ) in a direction of transport of the workpiece ( 4 ), the detection device configured to cooperate with at least one of the transport device ( 7 , 11 ) and the printing cylinder ( 5 ) so that the transport of the workpiece ( 4 ), prior to reaching the printing gap ( 3 ), is accelerated or delayed and/or an angular position of the printing cylinder ( 5 ) is changed by accelerating or delaying a rotational motion thereof in order to bring into agreement a beginning of the printed image with the workpiece front end ( 9 ) or a determined relative position thereto.
