[0002] In the production process of flexographic plates and resin plates, it is necessary to perform photosensitive radiation on the flexographic plates through a UVLED surface light source. The main principle is that after the UVLED surface light source is lit, the heat radiation generated is used to perform radiation curing operations on the surfaces of the flexographic plates and resin plates.
