The problem of color difference in carton printing can be solved from these five aspects!

When the carton is printed, the printing press will often be used for a period of time and the printed product will change color, which makes our printing press master a headache; it also takes a lot of time and money to repair. For this situation, Shenzhen Xinhongyang Packaging Products Co., Ltd. will introduce a few better methods for you, hoping to help you.

1. When the carton printing is discolored, first check whether the design layout of our printed matter is reasonable, for example, put a pattern with a relatively large amount of ink on the drag position. Such a layout design is definitely not conducive to our printing of high-quality printed matter. , You can try to put it in the position of the mouth, which is conducive to the control of the paper by the gripper, and it is not prone to discoloration.

2. The quality of the ink circuit system is also the problem of color difference in carton printing. If the color changes occur, we should check whether the ink circuit system is normal.

3. When trial printing, it is best to choose better coated paper for trial printing to avoid the influence of paper quality. For thinner paper, we should open the air volume on the embossing as small as possible, and for thicker paper, we should use a moderate amount. If the color is changed when it is opened, we can use a magnifying glass to observe the dots on the printing plate to check whether there is any deformation.

4. This situation may occur in the waterway, and the pressure of the middle roller needs to be specially adjusted. It is best not to use the middle water roller in the printing process under the condition of insufficient technology.

5. If the above methods have been tried but did not solve the problem of discoloration, then we have to consider the problem of teeth and need to remove the spring for cleaning.
