There are some things to note in the paper bag printing process

In the process of printing paper bags, there are some matters that need to be paid attention to by the paper bag printing manufacturers, and the matters needing attention when printing the paper bags.

1. In order to ensure the quality of the ink when printing the paper bag, it is necessary to control the room temperature. Avoid direct exposure of the ink to light, and avoid too thick ink to thicken. The best room temperature should be controlled at 10 to 26 degrees Celsius.

2, paper bag is a high-speed printing, the speed is very fast in the printing process, so there are certain requirements for the drying of the ink. If the drying speed of the ink is too slow, a desiccant may be appropriately added to increase the drying speed. If the printing ink is not dry, it is easy to produce a version. When the surface is sticky, it also affects the overall printing efficiency.

3. In the process of printing paper bags, if the ink is not stirred frequently, it is easy to bond, which will affect the overall effect of the paper bag. But be careful not to dilute too much, because the print will have a color, you can add a thickener to adjust.

4. The printing machine should be cleaned immediately after the printing of the paper bag, so as not to take a long time, all the inks on the machine are glued with different colors, which will affect the next printing effect.
