Several treatment methods of film wrinkle in the process of film gravure printing
film wrinkle is inevitable in the process of film printing. How to deal with this situation is introduced
1. First, check whether the shaking of the main rod of the printing plate during high-speed rotation is greater than 0.1mm ~ 1mm, whether the door plugs are all weighed, whether the door plugs are on the central axis during plate loading, and whether the shaking range is also between 1mm ~ 1.2mm. If the shaking is too large, the printing roller plate is uneven, tight on one side and loose on the other, so as to wrinkle the side. Treatment method; 3A composite materials contribute to the sustainable design of water taxis, and reduce the error shaking rate of the main stick of the printing plate to a minimum, or the door plug is placed stably to reduce the shaking of the printing plate
2. When printing the embossed plate of leather stick, there is a problem that one side is high and the other side is low. Adjust the low direction and slowly press down until both sides of the film are flat
3. The aluminum roller of the printing film into the printing plate or out of the printing plate after printing is uneven. Adjust the aluminum roller level
4. We remove the unqualified parts and correct the printing film. During high-speed printing, the ink is stuck on both sides of the printing roller, or the printing roller is uneven. Treatment methods:
① remove the ink stuck on both sides of the printing roller and replace the good printing roller
② remove the ink stuck on both sides of the printing roller, move the printing roller to the right 1mm ~ 3mm away from the film, continuously print the empty part, thicken or subtract the thickness of the uneven printing roller, and press it to be smooth, tough and elastic
we are also studying how the double-layer pressing plate composed of vacuum is connected together by adhesive 5 The thickness of the edge of the printing film is uneven, the unwinding tension of the printing film is too large to cause jumping, and the tension during winding is too small to cause uneven stress 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
