There are two primary types of Watermarking processes in the industry. The first is performed when the paper is being made, whereby a brass screen with an image brazed onto the wire rotates on top of the still wet mat of paper fibers, impressing the image into the surface. The second method uses a polymer relief plate to apply a chemical that makes a faint image into the paper. True watermarking is for large quantities of paper, and for smaller runs of 10,000 sheets and up the second method makes a "watermark" available to a wide range of end users.
Subtle yet distinctive, watermarking is an additional element for any corporate identity.
