It has the characteristics of oil storage, oil permeability and light flash melting. Photosensitive materials can absorb light energy and convert it into heat energy when they are irradiated by strong light. The darker the color, the more energy they absorb.

when exposed, the surface of photosensitive material instantly absorbs a large amount of light energy, and then the temperature rises rapidly and reaches the melting point. After flashing, the temperature of surface melt drops rapidly, forming a thin film with a certain thickness and strength, which plays the role of sealing the hole and sealing the hole, and isolates the penetration of printing ink.
