SCREEN PLATE ENHANCEMENT LIQUID AND METHOD OF PROCESSING SCREEN PLATE WITH THE SCREEN PLATE ENHANCEMENT LIQUID

摘要

PROBLEM TO BE SOLVED: To solve such problems that a screen plate used for screen printing recently adopts a method by inkjet such as digital screen plate making, however, ink has adverse influences on the screen plate, and measures against the ink deteriorates in water resistance and endurance.;SOLUTION: The screen plate enhancement liquid mainly includes: glutaraldehyde; hydrochloric acid; and water, and substantially improves water resistance and endurance of the screen plate by adding specific additives. The additives are selected from alcohol, glycol, and fluorine compound, and one or more of the additives can be added. All of the screen plates are processed with the screen plate enhancement liquid. Thus, the water resistance and endurance of the image is substantially improved, corresponding to thin line printing. Drying speed is accelerated by adding alcohol. Crack of the screen plate is prevented by adding glycol. Overall unevenness is reduced and stable hard film processing is achieved by fluorine compound.;COPYRIGHT: (C)2013,JPO&INPIT
