Off tracing paper to dry after a few minutes away. If the paper is not gone completely, usable cotton touch water wipe. Blank part with lacquer coating layer, screen mesh plug. Printing after dry. Organic glass screen printing manufacturers printing plate technology standard is what? 2, carbon paper plate burning method: is a kind of relatively simple manual plate making method. ( 1) Sensitive paper cutting, paper is a kind of mixture thicker coating and oxygen barium base paper made of carbon paper, according to the size of the graphics lay aside. ( 2) Sensitization: in 500 and 20 g in the preparation of ammonium dichromate solution soak for 3-5 minutes, remove carbon paper, the water distribution. ( 3) Exposure: stick carbon paper flat in a clean glass, film, coating on the male figure polyester film negatives, using printing-down machine exposure, exposure time 8 to 12 minutes. ( 4) Development: after exposure in 40 ~ 50 degrees warm water soak for a few minutes, the film and Yang chart with zinc oxide base paper from nature, carefully developed with warm water to form the text clear so far.
