Abstract: In a method or system for automatic controlling of jobs to be processed, the jobs to be associated with input and output material bundles, the jobs to be processed are collected into multiple groups or clusters. The groups or clusters are automatically sorted according to rules. The input material bundles are fed to a processing device at a central station, at least one post-processing apparatus being connected to and down stream from the processing device.

Abstract: In a method or system to generate a document data stream of a first format that is serially structured per page, document data of a second format that comprise multiple pages of a document are linked with the document data stream. In the document data stream of the first format a separate characteristic type mapping is provided that indicates that contiguous document data that comprise multiple pages are linked with the document data stream. In the first format a first page of the multipage document is completely and successfully run through a parsing process before document data of subsequent pages are run though the parsing process.

Abstract: In a method/device for preparing a print data stream for generation of print images with at least two primary colors, the print data contained in an input print data stream are supplied to a processing stage as input print data. The input print data are processed with the processing stage wherein at least one raster image of a first primary color is generated. Trapping information is generated by use of the raster image. An output print data stream is generated that has the trapping information in addition to print data.

Abstract: A method and system for printing of gray scale images utilizes raster image data. A page is divided into tiles in a two dimensional grid. Tiles are checked for the presence of dither cells for generating gray scale values. Tiles without dither cells are compressed for transmission while tiles having dither cells are not compressed.

Abstract: A method and a device for accessing data wherein the data is sequentially stored as data objects. The data objects are identified by a control variable having consecutive integer values. The control variable and the memory address is determined of a first known data object and an estimate for the size of a data object is determined therefrom. The control variable of the requested data object is multiplied by the estimate, as a result whereof an initial value for a memory address of the requested data object is formed. The actual control variable of the data object stored under the initial value is determined, the search for the requested data object being terminated in the case of correspondence between the actual control variable and the desired control variable, and otherwise the search is continued.

Abstract: In a method or system for processing of print data, a print data stream with print data of a plurality of print pages is generated wherein at least one first object property is associated with at least one region of the print pages. The print data are processed wherein at least one part of the at least one region of one of the plurality of print pages of the print data stream is selected. At least one second object property differing from the at least one first object property is associated with the selected part of the region on each of said plurality of print pages of the print data stream. The print data of each of said plurality of print pages which pertain to the selected part of the region are further processed dependent on the at least one second object property.

Abstract: A method of printing a highlight color image uses half-tone printing reference patterns for generating printing values for a print original image for a standard color and for generating printing values for a print original image for a highlight color. The information pertaining to the color values of the original image that are assigned to a standard color region or to a highlight color region is integrated into the half-tone printing reference patterns, whereby the printing of a highlight image is limited to a selection of the corresponding half-tone printing reference pattern and the acceptance of the printing value indicated in the half-tone printing reference pattern. Only one corresponding selection for determining the printing values for the standard color and for the highlight color is carried out for each image point.

Abstract: In a method and printing system for mapping of color values of a color image to color values of a highlight color image with two highlight color colors, a mapping rule is developed such that a range in which a color value of the color image can be mapped to both highlight color colors is limited to a range between the two highlight color colors. Also, mapping rules for mapping of the color values to one of the two highlight color colors are designed such that they produce only a small portion of the highlight color color to be mapped in a neighborhood of the respective highlight color color that is not to be mapped. A color impression caused by highlight color colors of the color image is thus retained. Additionally a darkening of the color image via an application of too much toner of both highlight color colors is avoided.

Abstract: The invention relates to a method for printing an HLC image (Highlight Color image). The invention utilizes half-tone printing reference patterns for generating printing values for a print original image for a standard color and for generating printing values for a print original image for a highlight color. The information pertaining to the color values of the original image that are assigned to a standard color region or to an HLC color region is integrated into the half-tone printing reference patterns, whereby the method for printing an HLC image can be limited to the selection of the corresponding half-tone printing reference pattern and of the acceptance of the printing value indicated in the half-tone printing reference pattern. Only one corresponding selection for determining the printing values for the standard color and for the highlight color is carried out for each image point.
