Method for proofing imposed documents

A method for producing proofer data for printing sides of a set of proof sheets from printing data of a document, the document having one or more sections, each proof sheet having a recto side and a verso side, said printing data comprising printing information about printing a set of pages onto one or more print sheets and about the contents of the pages in the set of pages, and imposing information about how the set of pages are positioned on the print sheets, each print sheet including two print sheet sides, a verso print sheet side and a recto print sheet side, each print sheet side including at least four pages, each proof sheet comprising a printer spread of at most two pages, the method comprising:

• for the pages of a particular section in a particular print sheet in said printing data,
• (a) choosing a first page of said particular section;
• (b) for the chosen page,
• (i) determining if the chosen page is in the first half of the particular section, and if the chosen page is in the first half of the particular section,
• determining the printer spread which includes the chosen page and positioning the chosen page in the printer spread so that when the chosen page is head-up, the chosen page is located on the left of the one side of the proof sheet and the printer spread which includes the chosen page also includes the page immediately to the right of the chosen page in the printing data for the case of the one side of the proof sheet being the verso side and chosen page is located on the right of the one side of the proof sheet and the printer spread which includes the chosen page also includes the page immediately to the left of the chosen page in the printing data for the case of the one side of the proof sheet being the recto side, and
• determining the logical order of the proof side on which the chosen page is located;
• (c) choosing a next page in the particular section and repeating step (b);
• (d) repeating step (a) until all pages in the particular section have been chosen;
• and
• (e) repeating step (b) until all pages in the printing data have been chosen.

A computer software product comprising:

• computer readable storage medium with computer readable code embodied therein for causing a computer to produce proofer data for printing sides of a set of proof sheets from printing data of a document, the document having one or more sections, each proof sheet having a recto side and a verso side, said printing data comprising printing information about printing a set of pages onto one or more print sheets and about the contents of the pages in the set of pages, and imposing information about how the set of pages are positioned on the print sheets, each print sheet including two print sheet sides, a verso print sheet side and a recto print sheet side, each print sheet side including at least four pages, each proof sheet comprising a printer spread of at most two pages, and wherein the computer readable code comprises:
• (a) computer readable program code devices configured to cause said computer to affect a selection mechanism configured to select a page in a particular section of the printing data;
• and
• (b) computer readable program code devices configured to cause said computer to affect a positioning mechanism configured to determine the printer spread which includes the selected page and to generate proofer data corresponding to the selected page, the corresponding proofer data including positioning information for positioning and printing the printer spread which includes the selected page on one side of a proof sheet of the set of proof sheets.
