Abstract
A printing machine utilizes several printing couples to produce at least one printed image on a printed material. Compensation for at least one of a longitudinal elongation and a transverse elongation of the printed material is accomplished. An anticipated elongation of the printed material is compensated for by matching of a printed image placement, with respect to length, width or position, with an imaging system generating the printed image placement on a printing form.
