Welcome to the Xianghuai Website.We are mainly engaged in designing and manufacturing flexographic printing machines.

For plastic film printing presses, it is very important to perform reasonable operations when printing. What should you pay attention to during the operation? Let's take a look at it.

1. The temperature is not suitable, especially if the oven temperature is too high, the temperature of the chill roll is too high to deform the film, and the temperature of the preheating box should be appropriately increased for the film which is not flat.

2. The tension setting of the substrate is unreasonable, the tension is too small, the substrate is slack, and the vertical and horizontal color registration are not accurate; the tension is too large, the substrate is lateral, the shrinkage and the longitudinal color registration are unstable, and accordingly the tension is adjusted accordingly.

3. The installation of the plate roller is not suitable. If the eccentricity is generated, the ink on the plug must be wiped clean before the plate roller is installed.

4. The air volume in the oven is unbalanced, causing the film to shake in the oven, and the anemometer is used to measure the amount of air in and out and to control it.

Therefore, plastic film flexo printing machines should pay attention to these details during the operation to ensure their good performance.
