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.
