If the screen is used, first of all to screen to oil, dust, still need to wash the residual ink, etc. Clean the screen with cleaning agent, should choose a new purchase of concentrated washing agent, zui no household detergents or washing powder, because it contains essence and armguard agent ( Detergent) And bleach ( Washing powder) Additional ingredients, and the particle plugging. When used in network agent cleaning screen printing plant, to both sides of the screen all evenly daub, with sponge wiped repeatedly. Then rinse clean water will be silk screen, and dry, ensure there is no residual bubble, silk screen and screen after washing, don't again to touch by hand. After the cleaning should be in a drying screen without dust environment. Now there are still many people who live on the fan on the screen of the dry method, but the dust is bigger, zui good do a drying oven, for uniform air flow through the screen surface. At the same time try to be on the same day to wash the net, the coated photosensitive glue, this prevents screen again fall dirt before coating. If the operation site of humidity is very big, zui good device for a dehumidifier, to speed up the network version of drying. Will people still using coarsening agent, silk edge polishing rough, this method is suitable for use in the indirect method of plate making, the combination of light-sensitive membrane can be improved with silk screen fastness. If we use coated photosensitive glue legal system for screen plate, there is no need for roughening treatment, otherwise it will reduce the strength of the screen.
