Abstract:
This invention provides a metal sheet preparing process with a surface having wood grain, and the process includes the following steps: spraying photosensitive ink on the metal sheet; pasting a designed film on a surface of the metal sheet sprayed with the photosensitive ink; exposing the metal sheet pasted with the film in an ultraviolet light for 1-15 min; spray developing the surface of the metal sheet with sodium carbonate solution, and exiting the film after developing; etching the metal sheet exited the film after developing with a mixed aqueous solution of ferric trichloride and copper sulfate, and a corrosive temperature being 30-50° C. which lasts for 5-8 min; and washing corrosive liquid on the grain and cured films of the photosensitive ink out of the grain with sodium hydroxide solution of 5-8% wt %.

Claim (Index 4):
The metal sheet preparing process with surface having wood grain according to  claim 3 , wherein a weight percentage concentration of the sodium hydroxide solution is 5-8%.
