Abstract
The present invention relates to anti-counterfeiting coated white card paper and a production technique thereof. Cut and separated color fiber is uniformly dispersed by water; the color fiber is added into the paper pulp in a pulping working section or in a floating part at the base layer of a papermaking machine and uniformly dispersed to obtain base layer pulp; then, the base layer pulp is conveyed to the papermaking machine, and the base layer pulp and the surface layer pulp (or with the sandwich layer pulp and the lining pulp) are used for manufacturing paper together; therefore, the anti-counterfeiting coated white card paper of which the base layer is uniformly distributed with the color fiber is formed. After the color fiber added into the base layer pulp is manufactured by the papermaking machine, the color fiber is uniformly distributed on the base layer of the coated white card paper; because of the diversity and the distribution flexibility of the color fiber, specifical marks are easily formed to play an anti-counterfeiting function.
