Abstract

A method for processing a print job in a computer-aided prepress stage for which the print job comprises a number of same printed products (B), respectively containing several different pages (A). At least one of the printed products (B) comprises at least one page (A) with at least one additional information element (C) that differs from at least one additional information element (C) of at least one otherwise identical page (A) of a different printed product (B) and for which the pages (A) of the printed product (B) and the additional information elements (C) are transmitted to a computer used in the prepress stage. Pages (A) which appear multiple times in the printed products (B) are imposed only once and only the different pages (A) of a print job are ripped. A digital work list (E) generated from the print job is made available jointly with the ripped pages (A) to a digital printing press used to print the products (B) of the print job.

First claim

What is claimed is:

1 . A method for processing a print job in a computer-aided prepress stage, for which the print job comprises a number of the same printed products (B) with respectively several different pages (A), for which at least one of the printed products (B) of the print job comprises at least one page (A) with at least one additional information element (C) that differs from at least one other additional information element (C) of at least one otherwise identical page (A) of a different printed product (B) of the print job, for which the pages (A) of the printed products (B) of the print job are transmitted in a computer-readable page description language and the additional information elements (C) of the print job are transmitted in a computer-readable form to a computer used in the prepress stage for processing the print job, the method comprising:
imposing only the pages (A) of one printed product (B) of the print job via a computer, thereby creating imposed pages (D); copying at least one of the imposed pages (D), intended for accommodating the at least one additional information element (C), such that following the copying, the precise number of imposed and copied pages (D) exist which are required for accommodating the additional information elements (C) of the print job; inserting the additional information elements (C) into the at least one imposed page intended for accommodating it and into the at least one copied page (D); creating a digital work list (E) based on the print job which comprises a print sequence for the imposed and copied pages (D); ripping the at least one imposed and the at least one copied page (D) with the therein inserted additional information elements (C), as well as the additional imposed pages (D) that do not contain additional information elements; and making available to a digital printing press the ripped pages and the digital work list (E) for printing the printed products (B) of the print job.

2 . The method according to claim 1 , further including transmitting to the computer used in the prepress stage for processing the print job the pages (A) of the printed products (B) and the additional information elements (C) of the print job in separate input files or in a joint input file.

3 . The method according to claim 1 , further including using a PDF format for the computer-readable page description language.

4 . The method according to claim 1 , further including transmitting the additional information elements (C) from at least one electronic database and/or at least one file to the computer used in the prepress stage.

5 . The method according to claim 1 , wherein a print job comprises a number of additional, same printed products (B′), which respectively are provided with at least one identical additional information element (C) such as at least one of the same printed products (B), the method further includes supplementing the digital work list (E) by the number of said additional, same printed products (B′).
