Title:
FORM PAPER WITH WATERMARK
Document Type and Number:
Japanese Patent JP3444535
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To provide a form paper with a watermark, in which no change occurs with time and a watermarked ensign part can be easily formed.
SOLUTION: A light shielding ink made of an ultraviolet curing type paper color ink is formed locally on the surface of a base paper 3 so as to partitioningly form a watermarked mark part 2 due to the difference of the transmissiovies of a surface part, on which the light shielding ink is coated by printing, and that of a surface part, on which no light shielding ink is coated, in order to allow to visually recognize the watermarked ensign part through the transmission of light so as to constitute a form paper with a watermark. Thus, since the ultraviolet curing type paper color ink is employed, no change with time occurs unlike in a constitution of employing impregnation with an oily ink, and a fine design representation also becomes possible and, at the same time, no conspicuity beyond the surface of the paper develops.
