The invention relates to a process for cleaning high-precision
screen printing plates, which comprises the steps of: 1 rapidly taking down a
screen printing plate in one minute after printing, and collecting residual
silver paste on the
screen printing plate in two minutes; 2 simultaneously wiping the front side and the back side of the screen printing plate with non-
woven fabric wetted in a TM plate washing agent along the direction of mesh stretching angles; 3 after the both sides of the screen printing plate are cleaned by the TM washing agent, simultaneously wiping the front and the back sides of
graphics fields with non-
woven fabric wetted in a DM plate washing agent along the direction of mesh stretching angles, 4 checking graphs with lights, if partial graphs are invisible, simultaneously wiping the front and the back sides of the field with non-
woven fabric wetted in the DM plate washing agent along the direction of mesh stretching angles, until the graphs are visible, wherein the whole wiping process is not more than ten minutes; and 5 after the screen plating plate is wiped clean,
drying the screen printing plate with an
ion blower gun. The process can rapidly clean the high-precision screen printing plates completely, and is quite effective to plates with high-precision screen printing
silver paste that is difficult to be cleaned, has low cleaning cost, and guarantees the normal production.
