Abstract: PURPOSE: Forgery proof safety paper obtained by inserting a multifunctional watermark functioning as Braille dots and machine-readable elements into security paper is provided. Paper manufactured by this process is increased in bending and sagging of paper when piled up and also improved in printability and workability. CONSTITUTION: A multifunctional watermark is inserted with a thickness of 10 to 25 microns into the upper and lower blank at the opposite position of an inner watermark in a sheet of security paper, or 1 to 10 groups consisting of 3 to 7 watermarks are continuously disposed in a right and left blank as unprinted part of the safety paper and at the back face part of printing paper to produce forgery proof safety paper. The multifunctional watermark exhibits a specified pattern of a round shape or a polygon shape having a size of 3 to 10mm.

Abstract translation: 目的：提供通过将用作盲文点和机器可读元素的多功能水印插入安全纸中而获得的防伪安全纸。 通过该方法制造的纸张在堆叠时纸张的弯曲和下垂增加，并且还提高了可印刷性和可加工性。 构成：在一张安全纸中的内部水印的相对位置的上下两个空白处插入10到25微米厚度的多功能水印，或连续排列由3到7个水印组成的1至10组 在右侧和左侧空白作为安全纸的未打印部分，并在打印纸的背面部分生成防伪安全纸。 多功能水印呈现出具有3至10mm尺寸的圆形或多边形形状的指定图案。
