Inspection Standards for Color Printing Mills

Dalian color printing plant may cause poor drying of ink after printing due to the failure of photoinitiator in ink. Additives such as toner and visbreaker are often needed in ink. If the proportion of additives is too high, it may lead to too thin UV ink and poor drying. For five different reasons.

We also have a detailed description of preventive methods. It is better to do a good job of prevention than to analyze a bunch of high-quality treatment methods, because this can save processing costs and time, and improve work efficiency. So we must master it skillfully. It plays an important role in our life, no matter what product, in order to ensure that every user uses qualified products.

There will be relevant inspection standards to determine whether the quality is qualified. The following edition will introduce the inspection standard of color printing packaging for you. Designers should systematically and comprehensively grasp all the constraints in determining the size of the packaging box. There are many differences, such as the scattering and diffuse reflection of light in the exposure process. Ultraviolet radiation of common flexographic plate passes through vacuum layer, film base, emulsion layer and anti-halo layer. There are serious scattering and diffuse reflection problems.

However, the coating of digital flexographic plate is very thin when exposed, so there are only weak scattering and diffuse reflection phenomena. Without affecting the bonding of corrugated paper, the supply of binder for single-sided machine should be reduced, the moisture content of lining paper should be reduced, and the moisture content of surface paper should be increased. If the reverse warping is to be corrected, the operation is the opposite. Printing speed and ink drying speed will directly affect the ink rate of printed matter, so the change of printing speed and ink drying speed will cause the change of ink color on printed matter.
