Methods and apparatus for adaptive imposition templates
View Patent ↗Methods and apparatus are provided for receiving a print file having an actual page size, and a nominal imposition template specifying a nominal page size, and generating an imposition flat for printing. If the actual page size matches the nominal page size, the nominal imposition template is applied to the print file without change. If, however, the actual page size differs from the nominal page size, the nominal imposition template is automatically modified based on the actual page size, and then the modified imposition template is applied to the print file to create the imposition flat.
1. A system for adapting an imposition template to a print file comprising an actual page size, the system comprising:
an adaptive imposition template comprising a plurality of pages, wherein each page comprises a page location reference, the page location reference comprising an associated nominal page center and a nominal page size; and
a processor programmed for automatically:
receiving the print file and the adaptive imposition template;
determining whether the actual page size differs from the nominal page size;
when the actual page size differs from the nominal page size, perform the following:
determining the location of an actual page center of the actual page depending on a binding style and finishing parameters specified in the adaptive imposition template, the actual page size specified in the print file, and by performing the steps of:
retrieving at least one center axis separation attribute from the adaptive imposition template;
retrieving at least one vertical page separation attribute from the adaptive imposition template;
retrieving nominal page positions from the adaptive imposition template; and
setting said actual page center to the nominal page center by symmetrically aligning a vertical coordinate of the actual page with the nominal page positions and maintaining said at least one center axis separation attribute and said at least one vertical page separation attribute;
determining locations of associated page-dependent mark objects based on the location of the actual page center and the actual page size; and
modifying the adaptive imposition template by: modifying the location of the actual associated page-dependent marks based on the actual page size, deleting the nominal page and nominal associated page-dependent mark objects from the adaptive imposition template and adding the actual page and the actual associated page-dependent marks to the adaptive imposition template at the modified location.
2. The system of claim 1 , wherein the print file comprises a page description language.
3. The system of claim 2 , wherein the page description language comprises at least one of a portable document format (“PDF”), a PostScript, or a printer command language (“PCL”).
4. The system of claim 1 , wherein the mark object comprises a bleed mark.
5. The system of claim 1 , wherein the mark object comprises a trim mark.
6. A method for adapting an imposition template to a print file comprising an actual page size, the method comprising:
storing an adaptive imposition template in memory, said adaptive imposition template comprising a plurality of pages, wherein each page comprises a page location reference, the page location reference comprising an associated nominal page center and a nominal page size;
storing an application adapted to modify the adaptive imposition template wherein said application is adapted for:
receiving the print file and the adaptive imposition template;
determining whether the actual page size differs from the nominal page size;
when the actual page size differs from the nominal page size, perform the following:
determining the location of an actual page center of the actual page depending on a binding style and finishing parameters specified in the adaptive imposition template, the actual page size specified in the print file, and by performing the steps of:
retrieving at least one center axis separation attribute from the adaptive imposition template;
retrieving at least one vertical page separation attribute from the adaptive imposition template;
retrieving nominal page positions from the adaptive imposition template; and
setting said actual page center to the nominal page center by symmetrically aligning a vertical coordinate of the actual page with the nominal page positions and maintaining said at least one center axis separation attribute and said at least one vertical page separation attribute;
determining locations of associated page-dependent mark objects based on the location of the actual page center and the actual page size; and
modifying the adaptive imposition template by: modifying the location of the actual associated page-dependent marks based on the actual page size, deleting the nominal page and nominal associated page-dependent mark objects from the adaptive imposition template and adding the actual page and the actual associated page-dependent marks to the adaptive imposition template at the modified location.
7. The method of claim 6 , wherein the print file comprises a page description language.
8. The method of claim 7 , wherein the page description language comprises at least one of a portable document format (“PDF”), a PostScript, or a printer command language (“PCL”).
9. The method of claim 6 , wherein the adaptive imposition template further comprises a mark object having a location that depends on the nominal page size.
10. The method of claim 9 , wherein the mark object comprises a bleed mark.
11. The method of claim 9 , wherein the mark object comprises a trim mark.
12. A computer-implemented imposition process comprising:
via a computing device, receiving a print file comprising an actual page size;
via a computing device, receiving an adaptive imposition template comprising a plurality of pages, wherein each page comprises a page location reference, the page location reference comprising an associated nominal page center and a nominal page size;
via a computing device,
determining whether the actual page size differs from the nominal page size;
when the actual page size differs from the nominal page size, perform the following:
determining the location of an actual page center of the actual page depending on a binding style and finishing parameters specified in the adaptive imposition template, the actual page size specified in the print file, and by performing the steps of:
retrieving at least one center axis separation attribute from the adaptive imposition template;
retrieving at least one vertical page separation attribute from the adaptive imposition template;
retrieving nominal page positions from the adaptive imposition template; and
setting said actual page center to the nominal page center by symmetrically aligning a vertical coordinate of the actual page with the nominal page positions and maintaining said at least one center axis separation attribute and said at least one vertical page separation attribute;
determining locations of associated page-dependent mark objects based on the location of the actual page center and the actual page size; and
modifying the adaptive imposition template by: modifying the location of the actual associated page-dependent marks based on the actual page size, deleting the nominal page and nominal associated page-dependent mark objects from the adaptive imposition template and adding the actual page and the actual associated page-dependent marks to the adaptive imposition template at the modified location.
13. The imposition process of claim 12 , wherein the adaptive imposition template further comprises a mark object having a location that depends on the nominal page size.
