What is watermark paper?
Apr 01, 2018

The watermark paper is made of special chemical resin and special printing methods, so that the resin penetrates the paper, changes the light transmittance of the paper, and produces different light and dark preset watermark patterns when the light is transmitted through the visual inspection. This technology will not substantially damage the original texture and features of the paper, and it will not have any influence on writing or printing after printing.
