In a method, program, or device to generate or process a document data stream that comprises data relating to color management resources wherein processing of color-related data of the document data stream can be controlled, associating at least one indexed color management resource with the document data stream wherein with the management resource color-related data of the document data stream can be associated with multiple predetermined color palettes. Within a color palette, an index value is respectively associated with multiple color. Respective values regarding the index colors are stored in the color management resource. The values are associated with corresponding proportions of color tones to reproduce the respective indexed color. The color palettes are compared between the system that generates the document data and an output system that outputs the document data, the document data stream is structured.

Disclosed is a method for processing graphic data, specifically in a printer, wherein the source image to be processed contains source image elements arranged in a matrix, to each of which source image data is allocated. The target image obtained during processing contains target image elements arranged in a matrix, to each of which target image data is allocated. The source image is subdivided into partial source images arranged in a matrix. The target image data of a corresponding partial target image is determined for each partial source image on the basis of the source image data. Resolution is changed since the number of source image data of each partial source image differs from the number of target image data of each partial target image.

A method is provided for optimized color reproduction of a color original image by a color reproduction device. Color values of a color space of the original image are determined. A color space of the color reproduction device is determined. The color spaces of the original image and of the color reproduction device are compared and it is established which color range of the original image cannot be reproduced by the color reproduction device. Via a color adaption method, an adaption of the non-reproducible color range of the original image, and of a boundary range bordering this non-reproducible color range, to the color space of the color reproduction device is provided. Then an image-specific color association is generated. The original image is output by the image reproduction device according to the image-specific color association.

A method and printing system are provided for generation of a printed image, as is a data processing system for the conversion of printing data and a computer program for carrying out the method. On generation of a printed image, at least two adjacent raster blocks of image elements are illuminated with a light source. The surfaces of the raster blocks are charged dependent on the amount of incident light. On illuminating each raster surface, a portion of the light is also incident on the adjacent raster blocks. The photoconducting layer is charged in proportion to the total amount of incident light. The region colored with toner on the subsequent development of the photoconducting layer may be varied almost infinitely by varying the amount of incident light on the first and/or second raster surface, whereupon the line width of printed images is almost infinitely adjustable.

In a method to convert color-describing input print data suitable for graphical output with aid of an output apparatus into color-describing output print data, color proportions, defined by the input print data, of at least one region to be inked with at least two color separations, are determined, and a color space value to be generated with aid of the color separations is determined. An association rule is determined to convert the input print data into the output print data while retaining the color space value. A total areal coverage of areal coverages defined by the output print data of the color separations to generate the color space value is reduced relative to areal coverages of the color separations defined by the input print data. The input print data is converted into the output print data with aid of the determined association rule.

摘要:
The inventive method reduces the quantity of the actual number of pixels to be printed to attain a given resolution, on average, by half, with each two or pair of adjacent pixels of the original print information being sequentially processed to form a print pixel and a socalled white or unprinted pixel. The arrangement of print pixels and white pixels is effected so as to print a checkerboard pattern. The ink droplets accordingly have the smallest possible substrate or print media contact area so that adjacent ink droplets which are not yet dry are effectively prevented from running together and thereby degrading the resulting image.
