Abstract

An antifake digital printing quality control system comprises a base. Paper feeding rollers and paper discharging rollers are mounted on the base and fixedly mounted at two ends of the base respectively, printing paper is arranged between the paper feeding rollers and the paper discharging rollers, a linear array CCD (charge coupled device) camera is arranged on the upper portion of the printing paper, a planar array CCD camera is arranged on the lower portion of the printing paper, supporting rollers are arranged between the paper feeding rollers and the paper discharging rollers, a supporting roller belt is arranged on the supporting roller and positioned on the lower portion of the printing paper, and a transparent window is arranged on the supporting roller belt. The printing paper is supported up through the supporting rollers, images are collected by the planar array CCD camera through the transparent window, and image collection is realized through the planar array CCD camera in the process of maintaining the printing paper flat, so that accuracy of collected information is guaranteed, reliability in quality control is ensured, and space is not increased.

Description

technical field [0001] The invention relates to a printing device, in particular to an anti-counterfeiting digital printing quality control system. Background technique [0002] In the anti-counterfeiting digital printing process, the printing quality control adopts the area array CCD camera to collect the information on the bottom of the printing paper, and the line array CCD camera to collect the information on the top of the printing paper. The collected information is compared with the standard pattern to adjust the printing position. The area array CCD camera is installed at the bottom of the printing paper. Due to the large volume of the area array CCD camera, a large part of the printing paper collection part is suspended, and the printing paper is bent downwards and deformed, resulting in deformation of the image collected by the area array CCD camera, resulting in comparison errors. , affecting the accuracy of quality control. Contents of the invention [0003] ...
