Problems solved by technology

[0007] In the process of realizing the present invention, the inventors have found that there are at least the following problems in the prior art: in the prior art, when it is necessary to use the above-mentioned previously printed portable document file for reprinting, there is no guarantee that the previously printed portable document file The page dot matrix generated when the file is reprinted is consistent with the page dot matrix generated when the previously printed portable document file was printed for the first time, so that the quality of the entire reprinted file is poor, and printing accidents are prone to occur

Abstract

The embodiment of the invention discloses a method and a device for checking a page dot matrix, and relates to the technical field of digital printing. The method for checking the page dot matrix provided by the embodiment of the invention comprises the following steps of: acquiring a previously printed portable document file which comprises a checking parameter; checking files in the previously printed portable document file according to the checking parameter in the previously printed portable document file so as to provide a checking result; and performing corresponding processing on the files in the checked portable document file. By using the embodiment of the invention, the quality of reprinting can be greatly improved, and the probability of printing accidents is reduced; and compared with a dot matrix storage mode in the prior art, the method has the advantage that: a storage medium required by reprinting can be saved.

Description

technical field [0001] The invention relates to the technical field of digital printing, in particular to a page dot matrix verification method and device. Background technique [0002] With the rapid development of digital printing technology, the traditional printing process is being replaced by digital printing workflow. The digital printing workflow is a production process based on digital printing information. The production process mainly includes: prepress workflow, printing workflow, and postpress workflow. Wherein, the pre-press workflow has also changed from the PS (PostScript) format-based workflow in traditional printing to the Portable Document Format-based workflow in digital printing. The steps of the workflow with Portable Document Format as the core in the digital printing are as follows: [0003] Step 1: Convert PS files or non-standard portable document files into standard fixed-size portable document files. This process is generally called normalizatio...
