For solvent-based inks or UV inks, use a mixed solvent (such as alcohol) with a lower concentration that matches the plate for cleaning. For water-based ink, it can be cleaned with alkaline liquid cleaner or high-grade cleaning solution for flexographic printing. and do not use a hard brush to prevent scratches on the printing plate. After washing, dry the printing plate with a piece of lint-free cloth, be careful not to rub the printing plate repeatedly, and seal it up for later use after drying.
