photosensitive plate
The photopolymer plates have two layers: the upper is photopolymer layer and will solidify after UV exposure, while the rest part without exposure can dissolve in the water.
Notes

1. They must be stored in cool, dry place with the photosensitive face down and out of light. The room temperature should be between 50F-77F (10¡æ-25¡æ).

2. They mustn¡¯t be of heavy pressure. Don¡¯t move them frequently to prevent protecting film and the photosensitive layer from shelling which will cause oxygen crystal.

3. Don¡¯t tear off the protecting film if not use. The left part should be used up within a short period.

4. If it is stored for a long time, when you tear off the protecting film, there maybe a layer of water, just dry it in a lower temperature or by hairdryer, then it can be used as usual.
