Abstract

An antifraud color watermark paper is made up through printing antifraud color pattern on raw paper, winding, coating functional paint and winding agent. Its advantages are high antiforge power and simple technology.

Description

Technical field: [0001] The invention belongs to a processing method of anti-counterfeiting paper, and relates to special paper processed by printing and coating. Background technique: [0002] Paper anti-counterfeiting can be divided into two categories: paper-making anti-counterfeiting and paper processing anti-counterfeiting. Common anti-counterfeiting technologies in papermaking include watermark paper produced on a multi-net paper machine, and anti-counterfeiting paper with colored fibers, fluorescent fibers, and magnetic fibers added to the paper. The advantage of papermaking anti-counterfeiting is strong anti-counterfeiting ability, but its disadvantages are also obvious. For example, it is not suitable for small and medium batch production, and the cost is high. For the anti-counterfeiting identification of colored fiber, fluorescent fiber, and magnetic fiber paper, special equipment is required. Facilitate public identification. The common anti-counterfeiting prod...
