1. First see if the shaking of the main stick of the printing plate during high-speed rotation is greater than 0.1mm ~ 1mm, whether the door plug is uniform, whether the door plug is on the central axis in the plate installation, and whether the shaking range is also 1mm ~ 1.2mm If the shaking is too large, there will be unevenness in the platen of the printing roller, which is tight and loose at the same time, so that the edges are wrinkled. Treatment method; reduce the error shaking rate of the main stick of the printing plate to the minimum or the door plug is placed smoothly to reduce the shaking of the printing plate.
2. There is one side high and one side low when printing leather stick press plate, adjust the direction of low, and slowly press down until both sides of the film are flat.
3. The aluminum roller of the printing film entering the printing plate or printing out the printing plate is uneven. Adjust the aluminum roller level.
4. When the printing film is printed at high speed, ink is stuck on both sides of the printing roller, or the printing roller is uneven, the processing method:
â‘ Remove the ink on both sides of the printing roller and replace the printing roller;
②Remove the ink on both sides of the printing roller, move the printing roller to the right to 1mm ～ 3mm away from the film, continuous printing of the vacant part, thicken the uneven printing roller or reduce the thickness of the printing roller to smooth, tough, and elasticity.
5. The thickness of the edge of the printed film is not uniform. The unwinding tension of the printed film is too large, causing jumps. When the rewinding is too small, the tension is too small, which causes uneven loading. Treatment method: change the membrane, measure the membrane, reduce the tension control, and find the magnitude of the gravity according to the formula to make the force average.
Cutting with a dull Kitchen Knife will be dangerous. you have to work harder to slice through whatever you`re cutting means you`re more likely to cut yourself. Fortunately, it`s easy to sharpen a knife yourself with a whetstone or a honing rod(sharpening steel).
For a knife, it's necessary to keep it sharp while using.
