Abstract:
     A needed pattern is taken on a negative film and an image is formed on a silk screen coated with photosensitive material. By use of silk-screen printing, the pattern is printed on an aluminium plate. Acid is used for selective weak etch. Going through anode oxidation and spraying surface with a coating of protecting film, a patterned aluminium plate is finished with the features of simple technology, beautiful pattern and corrosion resistance.
