Abstract: According to the method and system for display screen-aided generation of an electronic document from rastered image data, a group of image data per page and comprising multiple pages is stored. Symbols for associated pages of the group per associated page are displayed in an organized structure in the first screen region. Per page or per region, the image data is separately selected for full display in a second screen display region so that the associated page is accessible for additional processing steps with respect to at least one of the elements selected from the group consisting of a pixel processing and a page processing. Upon touching a symbol of the group with a selection member, a content of the associated page of the group is displayed in an automatically opening, separate display region.

Abstract: In a method, a printing system and a computer program for trapping of print data with a plurality of objects, the print data are generated, prepared and/or transferred together with trapping instructions in a print data stream for execution of the trapping. The print data stream references resource data that comprise trapping parameters and/or trapping instructions. The method can be executed in real time without a delay in the printing process hereby occurring. It can therefore be integrated into a print data stream for electrographic high-capacity printers.

Abstract: The method or system for controlling a printing or copying system for processing single sheets, a first single sheet and at least a second single sheet immediately following the first single sheet is processed with aid of n processing units. A required minimum distance between the first and the second single sheet is determined for each processing unit. A delay distance is determined for the first and at least for each of the n?1 following processing units. A difference between the minimum distance of a processing unit and a sum of the delay distances of the preceding processing units is formed. A smallest possible distance with which the second single sheet is fed to the first processing unit after the first single sheet is determined by a highest value of the determined minimum distance of the first processing unit and the determined differences.
