What should I pay attention to when printing paper bags?

As the concept of low-carbon life matures, more and more shopping malls choose environmentally friendly paper bags. In order to give customers a better impression. In addition to high-quality services and products, in fact, the aesthetics of environmentally friendly paper bags cannot be ignored, and the probability of secondary use is greater, so they are sought after by many people. So, what should we pay attention to when printing paper bags? 1. The size and dispersion of the pigment particles depends on the ink film capillary for the glossiness of the paper bag printing. However, the apparent size of the pigment particles in the dispersed state is more important, which directly determines the state of the ink film capillary. Therefore, the pigment particles are small and well dispersed, which is very beneficial for paper bag printing. 2. The viscosity of the binder and the content of the pigment The capillary network structure formed between the ink pigment particles is an important aspect that determines the gloss of the paper bag printing. At the moment of embossing, the ink is pressed into the larger pores of the paper as a whole; after embossing, the binder begins to separate from the ink and penetrates into the smaller pores of the paper. Therefore, the size of the ink film capillary determines the amount of separation of the connecting material. The capillary's role in retaining the binder is much greater than the printing pressure that presses the binder into the pores of the paper. 3. Drying time The ink film dries quickly on the paper surface to reduce the amount of binder penetrating into the pores of the paper, thereby improving the gloss and smoothness of the ink film. The high gloss of the ink film means that the degree of specular reflection on the surface is relatively high, so that in most cases the human eye can see that the white light reflected on the surface is much less than that of the low gloss ink film, which makes the color saturation more high. Therefore, the high-gloss paper bag printing looks more colorful and fuller. Fourth, to prevent smearing on the back of the paper bag printing often has a full page solid, easy to cause smearing on the back. Use powder spraying to solve the problem. However, it should be noted that powder spraying will affect the surface gloss of the printed matter, and pollute the environment, and will wear and stick to the paper delivery of the offset printing machine. What needs attention is the correct arrangement of the printing color sequence. In order to avoid smearing on the back side caused by the collision of the paper when the imprint is not dry, the text and line plate should be printed first, and then the solid plate should be printed. 5. Post-printing craft paper bags need to be processed after printing, and the aesthetics and quality are even stronger. There are 12 kinds of post-press crafts. They are embossing, die-cutting, hot stamping, partial UV technology, freezing point snowflakes, reverse frosting, embossed hot stamping, lithographic paper, laser transfer, polishing and waxing, hot stamping, and laminating. The above are the issues that need to be paid attention to in paper bag printing. Of course, there are many details that need constant attention to get a beautiful and practical paper bag.
