Abstract
A method for creating a proof print in a web-processing printing press, for example a rotary printing presses for the industrial printing of packaging, includes using the printing press to print a print job and, thereafter, a follow-up print job and producing the proof print for the follow-up print job. A preferably flying web change from a first web to a second web is carried out, and the proof print is made on an end portion of the first web and preferably upstream of an adhesive join between the two webs or on an edge portion of the first web or of the second web. A proof print is therefore created and, in the process, waste is reduced and the proof print is straightforwardly provided for inspection.
Claims12
A method for creating a proof print in a web-processing printing press, wherein the printing press (1) prints a print job (50) and, thereafter, a follow-up print job (51) and the proof print (52) is carried out for the follow-up print job (51),
- characterized
- in that a web change from a first web (3a) to a second web (3b) is carried out, and in that the proof print (52) is made on an end portion (54) of the first web (3a) or on an edge portion (62) of the first web (3a) or of the second web (3b).
The method as claimed in one of the preceding claims,
- characterized
- in that the first web (3a) is wound up on a web roll (33).
The method as claimed in one of the preceding claims,
- characterized
- in that the printing units (22) for the follow-up print job (51) that are required for the proof print (52) are activated as the end portion (54) passes by.
