摘要:
A method for increasing the speed of color conversion from a plurality of color spaces to a single color space by reducing the number of color pixels by a factor of two prior to the color conversion step. This pixel reduction constitutes a lossy data compression scheme which takes advantage of the advance knowledge that the pixels will later undergo anti-aliasing by averaging subsequent to the color conversion. First the pixels are grouped into pairs, and one pixel of each pair is eliminated to form a pseudo halfpixel. The eliminated pixel is replaced with a tag identifying either the previous, current or next pseudo halfpixel. Then each pseudo halfpixel is color converted. Finally the indicated previous, current or next pseudo halfpixel, now color converted, is averaged with the current pseudo halfpixel to form a halfpixel, which is then averaged with the halfpixel above or below it to form an anti-aliased full pixel which can be displayed. The color conversion time of this process is roughly halved since half of the pixels are eliminated before the color conversion step and then effectively added back in after the color conversion step.

Apparatus and methods for raster image processing are provided that include a networked computer coupled to a plurality of networked printers, the networked computer adapted to receive a print job, parse the print job into one or more print pieces, load balance the print pieces among the printers based on color use and print speed, and provide a list of the printers that received the print pieces.

An automatic scanner calibration method and apparatus is disclosed in which a calibration target, such as a Kodak® gray strip, is attached to a scanning surface of a scanner. During a normal scan, the calibration target area can be ignored or scanned depending on user selection. If the calibration target is scanned, then the resulting information is used to calibrate the scanner automatically. Such calibration is more accurate than an older in time or preset default calibration. Another embodiment of the invention actuates a print of a printer calibration target on a printer on a scheduled basis. Thereafter, the user can take the printer calibration target and place it on the scanner and perform a calibration of a scanner/printer system.

The invention is relates to a simple, inexpensive high capacity output catch tray for copiers and other document production machines. The output tray automatically increases in capacity as the stack of copies in it accumulates, without external power source or control, while maintaining a relatively constant elevation relative to the copier output port, and automatically returns to its original position when partially or completely unloaded.

Techniques are provided for generating and using automated production and performance dashboards. For example, an automated production dashboard is generated and used that includes, but is not limited to, defining production performance metrics, job stats, trends, red/green/yellow with health check, and risks. As well, an automated upkeep dashboard is generated and used that includes, but is not limited to, defining supplies, maintenance, trends, next service appointments, red/green/yellow with health check, and risks. Such techniques may include a remote view of such dashboards, e.g. via native mobile applications in addition to web/client, etc.
摘要:
A method and system for scanning documents in a network environment and merging the resulting scan files with other documents into a printing workflow provides a user interface in which the user merges a scan file and a document file on a page basis by selecting thumbnail images of the desired pages and dragging and dropping the thumbnails so that a new merged document results. An alternative embodiment allows the user to apply predefined merge templates to the selected pages. The predefined merge templates may include printing and formatting instructions such as color settings and a page layout.
摘要:
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.
