Embodiment Construction

[0062] A printing quality evaluation and process control method, the method includes the establishment of enterprise production standards and printing process control two parts.

[0063] (1) The method of establishing enterprise production standards is as follows:

[0064] (1) On the basis of normal and standardized printing conditions, print standard proofs. The printed content includes: C, M, Y, K solid color blocks (in the form of measurement and control strips, printed on the jaws of the standard proofs), CM , MY, CY overprinted color blocks (in the form of measurement and control strips, printed on the mouth of the standard proof), C, M, Y, K four-color 25%, 50%, 75% dot color blocks (in the form of measurement and control strips, printed At the jaw position of the standard proof sheet), C, M, Y, K four colors 2%, 4%, 6%, 8%, 10%, 20%, 30%, 40%, 50%, 60%, 70% , 80%, 90% dot tone patches (color patches with more dot tone values ​​can be added, and the chromaticity measure...

Abstract

The invention discloses a printing quality evaluation and process control method. The method comprises enterprise production standard establishment and printing process control, is based on the international standard, the national standard or industry standard of the printing industry and the SPC (statistical process control) advanced quality control technology instead of powerful software and hardware process, uses the principle of statistics, and helps an enterprise to establish own production data and enterprise quality standard, so that process control for production of printed matters is performed on the basis that printing is stable and the printed matters meet standard specification, and printing standardization is realized.

Description

technical field [0001] The invention relates to an offset printing technology, in particular to an offset printing printing quality evaluation and process control method. Background technique [0002] At present, the domestic printing industry is developing in two polarizations. On the one hand, there are printing companies with high levels of automation, process, and standardization, which are in line with international printing technology. These companies have advanced quality control technology, equipment and supporting process software. Through Powerful software and hardware realize the quality process control of printed matter. However, the proportion of this part of enterprises is only rare in the entire domestic printing market; on the other hand, small and medium-sized enterprises account for the vast majority of our country. With the improvement of the quality requirements of printing products and the promotion of advanced printing technology and equipment, the tran...
