Abstract

A method and a computer data signal including instructions for processing printed unit orders for printing on printers adapted for printing N pages across a print web. The orders are grouped based on page type (e.g., size, thickness, color) and binding type into print batches. These print batches are sorted, processed and then sent to the printer. Printed units may be organized with N single printed units printed in parallel across the web, a single printed unit sorted into N sections printed in parallel across all of the webs, or in super batches including multiple printed units, with N super batches printed in parallel across the web.

Claims

1. A method of preparing a plurality of printed units for printing on a printer adapted for printing N pages across a web, each printed unit having a page type, a binding type and a page count, comprising:

grouping the plurality of printed units based on page type and binding type, the plurality of printed units including at least two different print units;

sorting the plurality of printed units within a group of similar page type and binding type by page count;

combining N printed units with similar page counts, and adding pad pages to any of the N printed units as necessary to form N print columns each having the same number of pages; and

,

processing the N print columns into a batch for printing.

2. The method of claim 1, wherein the method further comprises printing the batch on the printer so that across each web a page from each N print column is printed.

3. The method of claim 2, wherein the printer includes a finishing device and the method further comprises the finishing device slitting and cutting each web after printing into N stacks, each stack including the pages from one of the N print columns.

4. The method of claim 3, wherein any pad pages within the N stacks are removed so that each N print column includes the pages corresponding to one of the N printed units within the batch.

5. The method of claim 4, wherein the pad pages are marked to distinguish them from the pages of the printed unit and the pad pages are removed by an automated mark sensing device.

6. The method of claim 2, wherein the printer includes a finishing device for differentiating between the pages of successive batches upon receipt of an offset command and wherein the method further comprises printing multiple batches in succession and sending an offset command to the finishing device between each batch.

7. The method of claim 6, wherein the finishing device slits and cuts each web after printing into N stacks, each stack including the pages from one of the N print columns.

8. The method of claim 2, wherein the webs are output from the printer as a continuous fanfold sheets.

9. The method of claim 2, wherein the webs are output from the printer as individual sheets.

10. A method of preparing a plurality of printed units for printing on a printer adapted for printing N pages across a web, each printed unit having a page type, a binding type and a page count, comprising:

adding pad pages to equalize the number of pages within each of the N batches; and

,

processing each of the N batches into a super batch to print on the printer so that a first batch prints in a first page on the web, each successive batch prints in a successive page on the web, and the N batch prints on an Nth page of the web.

11. The method of claim 10, further comprising printing the super batch on the printer so that across each web a page from each N batch is printed.

12. The method of claim 11, wherein the printer includes a finishing device for differentiating between successive printed webs upon receipt of an offset command and wherein the method further comprises sending an offset command to the finishing device at the end of each printed unit within any of the batches.

13. The method of claim 12, wherein the finishing device slits and cuts each web after printing into N stacks, each stack including the pages from one of the N batches.

14. The method of claim 11, further comprising adding a book end mark to the last page of each printed unit within each batch.

15. The method of claim 11, wherein the printer includes a finishing device and the method further includes the finishing device slitting and cutting each web after printing into N stacks, each stack including the pages from one of the N batches.

16. The method of claim 15, wherein each stack is sorted into printed units.

17. The method of claim 16, wherein a book end mark is printed on the last page of each printed unit within each batch, and an automated mark sensing device is used to sort the printed units within each stack.

18. The method of claim 15, wherein any pad pages within the batches are removed.
