Abstract

The object of the invention is to achieve a correctly positioned print in duplex-printing mode. A method for the detection of marks ( 1, 1′, 1 ″) by a sensor array ( 10 ) for a printing machine has been provided, whereby the marks ( 1 ) on the first (recto) printing side ( 5 ) of a sheet ( 3 ) are detected, the sheet is turned over and shifted in a direction transverse to the transport direction, and the marks ( 1 ′) on a second (verso) printing side ( 6 ) of said sheet are detected. Furthermore, a printing machine is provided with an alignment device ( 40 ) for shifting a sheet ( 3 ) in a direction transverse to the transport direction for the detection of marks ( 1 ′) on the second printing side, said marks being offset relative to the marks ( 1 ) on the first printing side, after said sheet ( 3 ) has been turned over.

Claims (9)

1. A method for the detection of three set of marks by a sensor array for a printing machine, comprising the steps of:

applying the first set of marks located on the first printing side of a sheet in the transport direction, substantially in line with the third set of marks located on a transport belt for the transporting of the sheet,

detecting the first set of marks located on the first printing side of the sheet and turning over the sheet and shifting the sheet in a direction transverse to the transport direction such that the second set of marks located on the second printing side of the sheet are aligned in the transport direction, substantially in line with the third set of marks located on the transport belt,

and thereafter detecting the second set of marks on the second printing side of the sheet.

2. A printing machine for duplex printing on a sheet having two sets of detection marks, with one set of marks located on each printing side of the sheet, comprising:

a sensor array for detecting the first set of marks on the first printing side of the sheet,

a device for turning over the sheet,

an alignment device for shifting the sheet in a direction transverse to the transport direction aligned in the transport direction, substantially in line with a third set of marks located on the transport belt,

and after the sheet is turned over and shifted in a direction transverse to the transport direction, detecting the second set of marks on the second printing side of the sheet with said sensor array.
