What Is Photoengraving?

Photoengraving: This method was developed from photoengraving technology in the printing industry. The main process is to spray a layer of photosensitive adhesive on the surface of the copper roller that can generate a water-insoluble film after exposure. The pattern is subjected to color separation and photographic methods to make positive prints of various patterns. The positive prints are coated on a copper roller coated with photoresist for exposure. The photoresist on the unphotosensitive area can be washed away with water to produce a copper pattern.
