Printing press with a device for compensation of errors in the imaging of a forme cylinder

摘要

Printing press with a forme cylinder (1) and with an imaging system (6) with a along the surface of the printing cylinder (1) on a substantially to the longitudinal axis of the printing cylinder (1) parallel cross-pieces strength sodium axis (9) traversing from a drive device (10) driven printing head (7) and a device (11 to 14) for the correction of during the cross-pieces empirical errors occurring notably, the position of the print head (7) on the cross-pieces strength sodium axis (9), characterized in that it comprises a table (13) in which the rotation angles of the forme cylinder (1) corresponding positions of the print head (7) on the cross-pieces strength sodium axis as a table values (zw₁, Zw₂,.. Zw_n) are stored and that an angle - rotary encoders (4, 5) on the printing image carrier cylinder (1) is arranged, which generates signals corresponding to the angle, on the basis of which the table values (zw₁, Zw₂,.. Zw_n) from the table (13) can be called up, which by means of a counter (12) in feed signals for the drive device (10) of the print head (7) are reacted.
