1. First, look at whether the swing of the main stick of the printing plate is greater than 0.1 mm to 1 mm when the main stick rotates at a high speed. Whether the door stopper is called or not, whether the door stopper is in the center axis in the loading plate, and whether the shaking range is also 0.1 mm to 1.2 mm In between, if the shaking is too large, there are unevenness in the imprint of the printing roller, which is tight and one side is loose, so that the edge is wrinkled. Treatment method: Minimize the error roll rate of the main roll of the printing plate or the door plug is placed steadily to reduce the plate shake.
2. When printing platen roller imprinting plate, there is one side that is high, one side is low, and the lower direction is adjusted, 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 glued 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, and 2 remove the ink on both sides of the printing roller. The printing roller is moved to the right from the film by 1mm-3mm. The vacant part is continuously printed, and the uneven printing roller is thickened or the thickness of the printing roller is reduced to be smooth, flexible, and elastic.
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.
