Appl. No.:

09/770856

Inventors:

Margaret Motamed - Foster City CA
Alon Segal - San Francisco CA
Chew Yan Kong - Mountain View CA
Ravindranath Gunturu - Newark CA
Ghilad Dziesietnik - Palo Alto CA

Assignee:

Electronics for Imaging, Inc. - Foster City CA

International Classification:

G06F 1500

US Classification:

358 113, 358 118, 358 117, 358 12

Abstract:

A multiple raster image processor (RIP) system is described that enables faster system performance over multiple processors, and includes a zero RIP feature consisting of a language interpreter sub-RIP that interprets a print instruction file but does not process the graphics rendering steps or the post-language processing operators. A skip RIP interprets selected pages in a way that skips all or most of the processing for that page. Pages to be skipped are scheduled for a different processor, thereby saving processing time and enabling the provision of a multiple processor RIP.

International Classification:

G06F015/00

US Classification:

358 118, 358 11, 358 19, 358 115

Abstract:

The invention provides a printing method and apparatus, comprising a software application that works with proprietary printing utilities, and that may include one or more additional software components for adding additional printing technology. The invention also comprises an automatic print load-balancing component in a centralized or distributed raster image processing (RIP) printing environment that enables faster system performance over single or multiple processors.

Abstract:

A multiple raster image processor (RIP) system which enables faster system performance over multiple processors includes a zero RIP feature consisting of a language interpreter sub-RIP that interprets a print instruction file but does not process the graphics rendering steps or the post-language processing operators. The zero RIP discovers page related attributes for individual pages within a multipage job and reports any potential errors or warnings with the file. A thumb RIP consists of a very low resolution RIP that is used specifically for the creation of thumbnail images. A skip RIP interprets selected pages in a way that skips all or most of the processing for that page. Pages to be skipped are scheduled for a different processor, thereby saving processing time and enabling the provision of a multiple processor RIP. A rules based scheduler on an page/face or machine characteristic basis supports a dynamic assignment and assessment algorithm. Scheduling results in optimum use of available resources and requested print constraints (e. g.
