The printing process must go through pre-press, printing and other technical processes, in which the three sections of the film, printing, and printing will have a great impact on the deformation of the printed matter. This article focuses on the analysis of the causes of network distortion so that it can take timely control measures in production.
1. Dispense film: The process of issuing film consists of RIP dispensing, photosetter exposing the film and rinsing, inspection and other processes. The linearization of the film will not result in line drawing changes, printing effect is too dark, the picture color deviation, the level of reproduction is not good, the layout of the dirty, the virtual hair virtual, high and low tone network level lost and so on.
2. Shaiban: The data in the computer outputs the film through the film machine. After the printing, the dots will produce losses, the dots will become smaller and the appearance of rough spots around the dots. In actual production, the PS version outlets are prone to false halo, unreality, unstable printing colors, severe loss of high-light spots, un-evolution of printed images, and inequality of flat screens. The ability of the printing plate to express the tone is generally between 3% and 97% (adding the number of lines 1751Pi), due to the light scattering caused by the exposure of the high light tone and dark tone adjustment loss, the middle tone of the network is also inevitable phenomenon.
3. Printing: The printing link has the most obvious influence on the outlets. Because the printing process is complicated and the control of the conditions is also difficult, the following factors can be used to understand its impact on the outlets. First, the ink affects the transfer of dots. The ink is squeezed between the printing plate and the blanket. After being squeezed between the blanket and the paper, the formed ink layer is usually very thin. If the ink layer is thick, the dots will occur. The problem of enlargement; Second, the reduction of the dots needs to be effected by the ink roller pressure, and the ink roller pressure directly affects the ink transfer. Therefore, it is very important to properly adjust the working pressure of the ink roller.
