automatic flexo ink printer slotter die cutter machine precautions for the operation

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 guarantee layer of the resin plate is torn off, the photosensitive speed of the plate rapidly decays. The film should be immediately placed on the plate or subjected to main exposure within 10 minutes to obtain the best 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.

5. The printing plate must be dry, otherwise it will affect the thickness uniformity of the printing plate. After drying, do not let the printing plate come into contact with other object surfaces, and do not touch the printing surface with your fingers, otherwise marks will be left. But before debonding, it is necessary to remove any spots on the surface of the printing plate. After debonding, it is necessary to clean the residual spots on the back of the resin plate. If these things are not cleaned, it will affect the uniformity of the printing plate thickness and the adhesion of the plate mounting tape.
