At present, the quality of many commodity packaging does not go up, which makes consumers dissatisfied or even bored, which directly affects the sales of commodities. Under the current cruel competitive market conditions, it can not be said that it is a containment to businesses or carton manufacturers. Let's take a look with the small editor of carton manufacturers to see how to solve the problems encountered in whiteboard printing

1. In general, whiteboard paper is used to print more field products. Accordingly, the amount of ink is large. In order to reduce galling, the viscosity of ink and the thickness of ink layer should be strictly controlled during printing to prevent dirt on the back

2. Usually, a background color is printed first. The color of the background color can be diluted by the original ink color, or it can be consistent with the original ink color, and then overprint the original ink again, which not only reduces the galling phenomenon, but also solves the problem of ink sticking at one time. After two times of printing overprint, it also increases the gloss of the print at the same time

3. The surface of whiteboard paper is rough, loose, ink absorption is large, and flatness is poor. Therefore, the background color should be printed first, followed by dark color. The background color should be darker and thinner, and the ink color should not be too large. If the flatness of the whiteboard is good and the double-sided whiteboard is used, when printing the full plate on the spot, first print the dark color, and the amount of ink should be printed enough, subject to the fact that the back is not stuck, and then apply the background color thinly, so that the smoothness of the printing product will be better. At the same time, pay attention to the balance of water and ink and control the amount of water in the printing plate

4. When printing more products on whiteboard, try to use the original barrel of ink without ink blending oil, and appropriately add some de adhesion agent and anti adhesion agent; Do not add dry oil in hot weather. It is often easy to stick on the back of the printed full plate, which is often solved by powder spraying. Although the printing anti sticking and dirty dusting powder contains pure plant materials with good dispersion and fluidity, the use of dusting agent will directly affect the surface gloss of printing products, make the ink imprint not bright, pollute the environment and affect the accuracy of printing machinery

Through the above introduction, I have a certain understanding! If you want to know more relevant information, you can pay attention to carton manufacturers. Carton manufacturers provide you with better paper packaging
