Abstract: A method for improving the print quality of graphic elements, in particular vectorized letter graphics, in PDF documents in the prepress stage of a printing process by using a computer, includes analyzing the page content of the PDF document by using the computer and saving the page content in a suitable data structure, searching the data structure for graphic elements, in particular letter graphics, that fulfill specific predefined criteria relating to an evaluation of the height and width of the graphic paths of graphic elements that are present in the PDF document, by using the computer, converting the selected graphic elements into image masks by rendering the selected graphic elements on the computer and substituting the generated image masks for the originally selected graphic elements in the PDF document by using the computer. The PDF document with the generated image masks are printed on a printing machine.

Abstract: A method for creating PDF trapping objects from a PDF page description without a known contour description by using a computer for a printing process includes using the computer to generate a colored tiling pattern out of a part of the PDF page description without the top object to be choked, using the computer for clipping with a mask of the background object, using the computer for clipping with the top object or text to limit following frame additions to the top object, using the computer for adding a frame to the top object, using the generated colored tiling pattern as an inner frame between the background object and the top object, using the computer for adding a frame to the top object while activating overprinting of the background in the required object colors and using the computer for inserting the trapped top object into the PDF page description.

Abstract: A method and apparatus for producing a barcode on a substrate reproduce the barcode to adapt it during a workflow. All information about the barcode is procured and the page is reproduced. If not all the information about the barcode is known, problems can occur. Therefore, a first section is created within a first region in a file, describing a first barcode, the region is made unambiguously identifiable using identification elements of a PDL and, when re-opening, the file is identified using the identification elements and the first barcode is accessed. Changes can be made to individual parameters and/or contents of the first barcode and can be used to produce a changed first region. A substrate is then imaged in an imaging device producing the barcode while taking the changes in the image region into account. A data carrier stores a computer program for carrying out the method.

Abstract: A method for converting image data coded with run lengths to the format of a page description language, such as PostScript or PDF, the run lengths identifying how many image points of one color follow one another in an image row, includes utilizing the run lengths of the same color that overlap in successive image rows to form an object, and describing the object with operators from the page description language. Objects of the same color can be combined to form one object. An object is described in the page description language by the image mask operator and an associated bitmap, or by a polygon train that connects reference points on the edge of the object.

Abstract: A method for providing data for a sheet formed of at least two pages (content pages) within a workflow, in particular for creating a print, uses a data-processing device that contains at least one data storage device, a data input device and a monitor. A sheet is provided in the data storage medium, preferably a data storage medium implemented in a data-processing device, and contains the plurality of pages (content pages), preferably following an imposition scheme. The object is to form the creation of the content of a sheet such that it can be influenced (edited) for as long as possible. The content of each of the pages of the sheet is provided such that the respective page is provided in relation to a possible change and/or replacement and a changed or replacement page is then inserted into the sheet as a replacement.

Abstract: A method for producing a frame for a graphic object whose contour is defined by a sequence of Bezier curves is disclosed. To that end, a frame curve that is likewise a Bezier curve and that proceeds approximately parallel to the given Bezier curve is likewise produced for each Bezier curve of the contour. A mid-point PM is formed on the given Bezier curve. Proceeding therefrom at the spacing of the frame width, a mid-point QM for the frame curve to be produced is defined. The checkpoints of the frame curve are defined such that they proceed through the point QM.
