Embodiment Construction

[0032] Figure 4 The basic sequence of a preferred embodiment variant of the method according to the invention is schematically shown in . The PDF 9 includes one or more pages 11 , and the one or more pages 11 respectively include one or more text graphics 10 . In this case, the PDF page content 11 of the PDF 9 is analyzed by the computer 8 of the workflow system 6 and stored in a suitable data structure, which thus describes the entire content of the page 11 . here, image 3 A structural overview of the workflow system 6 is further schematically shown. In this data structure, colored, filled figures 10 are now specified which satisfy criteria 12 which can be parameterized by the user. Based on these criteria 12 that can be parameterized by the user, the computer 6 (or the corresponding program that runs on the computer 6 and executes the method according to the present invention) searches for text graphics 10 that meet the criteria 12 parameterized by the user in the PDF p...

Abstract

The invention relates to a method for improving the printing quality of graphic elements in a PDF document (9), especially vectorized text graphics, in a pre-printing stage of the printing process by means of a computer (6), comprising: a computer (6) ) analyze the PDF document (9) page content (11) and store the page content (11) with a suitable data structure; the computer (6) searches the graphic element (10) in the data structure: about existing in the PDF document (9) The evaluation of the height and width of the graphic path of the graphic element (10) meets the determined pre-selected standard (12); the selected graphic element (13) is converted into an image mask (14), and in the computer (6) The graphics element (13) of rendering selection; The graphics element (13) of original selection in the PDF document (9) is replaced by the image mask (14) generated by computer (6); In the printing press (7), printing has A PDF document (15) of the generated image mask (14).

Description

technical field [0001] The invention relates to a method for improving the print quality of graphic elements, in particular vectorized text graphics, by using an image mask. [0002] The present invention belongs to the technical field of digital prepress stage (Druckvorstufe). Background technique [0003] In the printing industry, in order to process printing orders, so-called jobs (Jobs) are created in the workflow system of the printing house, and these jobs contain all the necessary information for processing the printing order. These job information are usually stored in so-called JDF (Job Definition Files, job definition files). Here, these JDFs refer to job content data in PDF format. As a result, these JDFs have all the advantages and disadvantages inherent in the PDF standard. Thus, in the PDF standard, texts are usually represented by text (Schrift) in mostly True Type or Type-1 format. These texts have properties such as Hinting, Stammbreite, and capital lett...
