1,Consistency factor is related to the quality of custom printed cans.
The issue with the consistency factor is: how big can the variation between individual sheets be allowed? This is a question of quality and stability during printing on metal tins. With the increase in the number of prints on tin packaging box, the printing time is prolonged accordingly. During this time, the addition of various variables will inevitably be reflected in the print quality. In addition, due to problems with the printing plate endurance, sometimes the printing plate needs to be replaced halfway, or it may be due to paper. Failures in blankets and printing presses have to be stopped in the middle, so that the original water-ink balance relationship is disturbed. Once reprinted, its print quality cannot be consistent with the first print.
2. Technical factors are related to the quality of printing on metal tins.
After completing the format design of the printed manuscript and determining the printing method, ink, and tin packaging box printing material, it is the technical factors that can affect the printing on metal tins quality. Technical factors are the factors that affect the quality of custom printed cans in each process of printing production, and reproduce the designed content as faithfully as possible within the limits of the characteristics of plate making, printing equipment, and printing materials.
Technical characteristics of printing on metal tins quality include image clarity, color and level reproduction, glossiness and texture. Among these characteristic factors, some can be expressed quantitatively, such as color and coordination. In each step of the reproduction process, people can control these factors; there are some technical factors that cannot be expressed quantitatively, but can be described by language. . For example: in order to obtain the best printing on metal tins quality, the possibility of moire must be reduced to a minimum, which is the form described in language; another example is that the gloss characteristics will change depending on the end use. Readability requires low-gloss paper, but in order to achieve the best contrast for photocopying originals, high-gloss paper is required.
