Quality control method and control system for publishing documents based on open network transmission

Abstract

The invention discloses a quality control method and a quality control system based on an open network transmission publishing file, the method is applied to an editing file management system and a printing file management system, and an editing file management module generates a flexural printing file and an 8-bit TIFF file from an editing PDF file; the printing file distribution module is used for generating an encrypted copy file from the flexural printing file and the 8-bit TIFF file and setting permission and effective time; and the printing file downloading module decrypts the downloadedencrypted copy printing file to generate an 8-bit TIFF file, and compares the 8-bit TIFF file with the downloaded and decrypted 8-bit TIFF file. By means of the method, the problems of low layout plate making quality and low efficiency of a publishing house are effectively solved, network security transmission, content quality guarantee and copyright effectiveness control of printed files at thelayout plate making end, the publishing management end and the printing production end are efficiently achieved, and the publishing and printing work quality and efficiency are improved.

Description

technical field [0001] The invention belongs to the field of typesetting, publishing and printing, and mainly relates to edited documents, network transmission of printed documents, quality control, security encryption, authorization control and verification version comparison technology, specifically a quality control method based on open network transmission and publication documents ,Control System. Background technique [0002] With the continuous development of the publishing and printing industry in the direction of digitization, informatization, standardization, and greenization, film printing technology has been gradually eliminated, and CTP plate-making technology has been widely used. The printing plates used in printing have been replaced by electronic plates. (usually a printed PDF file). Electronic stencils have the characteristics of fast transmission, simple copying, and efficient secondary processing. Once the electronic stencils are sent out to the publishi...

AI Technical Summary

Problems solved by technology

Its own defects mainly include the following points: 1. With the popularization of CTP printing technology and equipment, each printing node currently has the technical processing capabilities of its intermediate nodes, and there is no problem that printing node technology equipment cannot meet the needs of CTP plate making; 2. .The central node transmits the format file to each printing node in the format of 1-bit TIFF. There are problems such as large data volume of the transmitted file and poor adjustability of the data file, which makes it difficult to meet the requirements of back-end printing, folding and other process changes; 3. The encryption and decryption authorization technology mentioned are all descriptive descriptions, and there is no detailed algorithm description for this technology, let alone the timeliness control of documents; 4. Although its system involves publishing and printing links, but in the above links How to ensure the standardization and unity of typesetting and printing documents, quality and safety control, and document validity control are not specified
