In the film printing process will inevitably wrinkle, how to deal with this situation, special introduction of several methods.
1. First look at the plate's main stick shake at high speed is greater than 0.1mm ~ 1mm, whether the plug is said, the door plug in the loading plate is in the center axis, the shaking range is also 1mm ~ 1.2mm In the meantime, if the shaking is too large, there is unevenness in the printing platen, and the side is tight and one side is loose, so that the edge is wrinkled. Processing method; minimize the error roll rate of the main plate of the printing plate or the door plug is placed steadily to reduce the plate shake.
2. There is a side high, one low, and a low adjustment direction when printing a stick printing plate, and slowly press down until both sides of the film are flat.
3. Printed film into the printing plate or printed version of the aluminum roller uneven. Adjust the aluminum roller level.
4. When the printing film is printed at a high speed, both sides of the printing roller are stuck with ink, or the printing roller is uneven. Processing method:
1 Remove the ink on both sides of the printing roller, change the printing roller;
2 Remove the ink on both sides of the printing roller, move the printing roller to the right from the film from 1mm to 3mm, print the empty part continuously, thicken the uneven roller or reduce the thickness of the roller to smooth, flexible, and elasticity.
5. The uneven thickness of the printed film edge, the film tension is too large to cause the beating, the tension is too small when rewinding, resulting in uneven force in and out. Treatment methods: Change the membrane, measure the membrane, reduce the tension control, and calculate the specific gravity according to the formula to make the force average.
