摘要： 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.

摘要： 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.
摘要翻译：通过使用计算机进行打印过程的PDF页面描述来创建PDF捕获对象的方法，包括使用计算机从PDF页面描述的一部分生成彩色拼贴图案，而不会使顶部对象成为窒息，使用计算机进行剪切与背景对象的掩码，使用计算机进行剪切与顶部对象或文本，以限制以下帧添加到顶部对象，使用计算机添加框架到顶部对象，使用生成的彩色平铺图案作为背景对象和顶部对象之间的内部框架，使用计算机在顶部对象中添加框架，同时激活所需对象颜色中背景的套印，并使用计算机将被困顶部对象插入 PDF页面描述。
