摘要:
A method for processing a print job includes: a) analyzing printer description language (PDL) image data for a print job; b) determining a raster image processor (RIP) orientation for the print job based at least in part on the analysis of the PDL image data, the RIP orientation being selected from a landscape orientation and a portrait orientation; and c) processing the PDL image data for each page of the print job to form raster image data for each page in the RIP orientation and storing the raster image data in the RIP orientation. A printing platform associated with the method includes a parser module, a controller module, a storage device, and a RIP module.

A method for processing a print job includes: a) processing printer description language (PDL) image data for a select page of a print job to form raster image data for the select page, processing of the PDL image data and storing the raster image data in a RIP orientation; b) processing the raster image data for the select page to form bitmap image data for the select page, transforming the raster image data from the RIP orientation to a print orientation and storing the bitmap image data in the print orientation; and c) printing the bitmap image data arranged in the print orientation on a target substrate page to form a printed substrate page for the select page of the print job. A printing platform associated with the method includes a storage device, a RIP module, a rotator module, and a print engine.

摘要:
A technique for selectively adjusting the quality of an image processing apparatus in relation to deviations from image quality standards including the steps of recognizing a deviation of the image processing apparatus from the image quality standards, responding to the state of deviation from the image quality standards by providing a plurality of time delays for adjusting the quality of the image processing apparatus, the time delays include automatically adjusting the quality of the image processing during a current job run, automatically adjusting the quality of the image processing apparatus upon completion of a current job run, and automatically adjusting the quality of the image processing apparatus upon a predetermined time delay after completion of a current job.
摘要:
A method and system are provided for reducing the bit depth of grayscale imagery using multi-bit halftoning. The halftoned image data may be lossy or losslessly compressed and stored in memory or transmitted over a communication channel. At the time of printing, the images are decompressed and reconstructed to a grayscale image data using Sigma filtering to preserve edges. Preferably, different Sigma filters may be applied based on contrast information within a local neighborhood region. Fuzzy edge detection may also be used to preserve edge features and prevent smearing.

摘要:
The presently disclosed embodiments are directed to methods and systems for improving the performance of an image processor color to color tile transformation by caching color tiles most recently calculated. A page of a print job is received. One or more color tiles based on colors found in a previous print job are pre-calculated and stored in a memory. A color present in the page is read. The color is compared to one or more pre-calculated color tiles. If the color does not match a pre-calculated color tile, a new color tile for the color is calculated, a pre-calculated color tile is removed from the memory, the new color tile is added to the memory, and the new color tile is used to print the page. If the color does match a pre-calculated color tile stored in the memory, the pre-calculated color tile is used to print the page.
