METHOD OF PRINTING UNIQUE PRINTS OR INDIVIDUALLY ASSEMBLED PRINTED PRODUCTS ON ROTARY PRINTING MACHINES

摘要

The image subject to be transferred is applied in preformatted form to at least two printing forms in the form of segment-like image data in a row and column arrangement, in such a way that a first portion of information from each segment of the image subject (information (a) with appropriate index features) is provided on a first printing form, and a second portion of information from the corresponding segment of the image subject (information (b) with appropriate index features) is provided on a second printing form. As a result of synchronous rolling of the printing-form cylinders, the portions of information are assembled to form complete information (<a,b> with the respectively combined index features) for each segment of the image subject on the printed page. For each printing-form cylinder revolution, the index features for each segment of the image subject (information <a,b>) are recombined step by step in the manner of a permutation, so that each printed segment constitutes a unique print.
