With the rapid development of society, every day can come into contact with a variety of packaging products, such as cartons, bags, etc., these are custom Others products Printing. Due to the improvement of living standards, the quality requirements of color box packaging are getting higher and higher, and there are also some problems. When custom Others products Printing, it is necessary to unify the overall color of the packaging box when printing the background color. At this time, if there are different colors, even the printing of the entire packaging will fail. What is the reason for this? Let's answer the following questions:

First of all, there are many different colors of the ink used, in order to solve the color difference of the offset printing ink on the plastic film, the offset printing ink should be used with relatively stable quality and small color difference. For printing products, try to use the same manufacturer of ink and printing products, and try to use the same batch of ink produced by the same manufacturer, some special color box packaging boxes need to be printed with spot color, so you need to adjust the ink once.

The second is that the ink circulation is not smooth, the ink circulation system is used to keep the ink circulation smooth, in order to ensure the convenience of adding diluents and new ink, the ink has good quality and fluidity.

Third, the printing speed is inconsistent with the ink drying speed, the printing speed and the ink drying speed will directly affect the inking rate of the color box packaging, so the change of the printing speed and ink drying speed will cause the change of the ink color on the color box packaging.

If the Printing quality is not good, it is easy to reduce the grade of the entire product, so if the product quality is poor due to poor printing quality, this is actually a pity, if the above three problems are solved, then there will be no color difference problem.
