In the film printing process can not avoid film wrinkle, in this case, how to deal with this situation, especially introduces several methods. 1. First, check whether the shaking of the main roller of the printing plate is greater than 0.1 mm ~ 1 mm when rotating at high speed, whether the door plug is evenly balanced, whether the door plug is on the central axis in the plate loading, and whether the shaking range is between 1 mm ~ 1.2 mm. If the shaking is too large, the printing plate is uneven, tight at one side and loose at the other side, so that the edge is wrinkled. Processing method: reduce the error shaking rate of the plate master bar to the minimum, or the door plug is placed stably to reduce the plate shaking. 2. There is a high side and a low side when printing leather stick imprinting plate, adjust the low direction, and slowly press down until both sides of the film are flat. 3. The aluminum roller of printing film entering or leaving the plate after printing is uneven. Adjust the aluminum roller level. 4. When printing film is in high-speed printing, ink is stuck on both sides of the printing roller, or the printing roller is uneven. The treatment methods are as follows: ① remove the ink on both sides of the printing roller, and replace the printing roller; ② Remove the ink on both sides of the printing roller, move the printing roller to the right to the position of 1 mm ~ 3 mm away from the film, and continuously print the empty part. Thicken or subtract the thickness of the printing roller to make it smooth, flexible and elastic. 5. The thickness of printing film edge is uneven, the tension of printing film unwinding is too large, which causes jump, and the tension is too small during winding up, which causes uneven force in and out. Treatment method: change the film, measure the film, reduce the tension control, and calculate the specific gravity according to the formula to make the force average.
