Abstract
본 발명은 워터마크와 엠보싱마크를 결합하여서 된 위조방지용 종이와 그 제조방법에 관한 것이다.The present invention relates to a forgery preventing paper made by combining a watermark and an embossing mark, and a manufacturing method thereof.
환망초지기에 의해 초지되는 지필에 워터마크를 형성시키기 위하여는 금망에 요철부를 형성시키므로서 요철부의 굴곡에 따라 지료섬유가 달리 쌓이게 하는 것인바, 이와 같은 자료의 쌓임이 바라는대로 정확할리가 없다.In order to form a watermark on the papermaking paper made by ring paper paper machine, the irregularities are formed in the gold mesh so that the paper fibers are piled differently according to the bending of the irregularities. The accumulation of such data cannot be exactly as desired.
그리하여 본 발명은 이와 같이 요철을 이루며 쌓인 지층에 임의형상 바람직하게 워터마크의 형상에 대응하는 형상을 가진 요철금형으로 워터마크의 상부를 압착시켜 워터마크에 선예성과 명백한 명암을 갖게 하므로서 은화의 정밀성, 다양성으로 실별력을 향상시켜 위조를 더욱 곤란하게 한 것임.Therefore, the present invention is a concave-convex mold having an arbitrary shape, preferably a shape corresponding to the shape of the watermark, on the stacked layers forming the unevenness, thereby compressing the upper part of the watermark to give sharpness and clear contrast to the watermark, Diversity improved the discrimination, making counterfeiting more difficult.
