Precautions for the operation of flexo printer slotter die cutting machine

1. By back exposure, the substrate of the plate can be established to obtain the required relief and enhance the adhesion of the polyester support film and photosensitive resin layer. The correct back exposure from the direction of the polyester support film can protect the subtle patterns of the plate during the development process and prevent the collapse of the relief.

2. After the back exposure, the main exposure should be performed immediately, as the photosensitivity will gradually disappear, resulting in a longer main exposure time and poorer exposure tolerance.

3. When the automatic flexo printing die cutting slotting machine guarantee layer of the resin plate is torn off, the photosensitive speed of the plate rapidly decreases. The film should be immediately placed on the plate or subjected to main exposure within 10 minutes to obtain the desired effect.

4. The main exposure time can be determined through the main exposure test. The photosensitive resin becomes insoluble through polymerization reaction, and the printing plate can reproduce the fine patterns on the film. Before performing the main exposure, it is necessary to manually wipe the vacuum film to expel air, so that the plate and negative film can fit tightly.
