Problems solved by technology

[0003] 1. This traditional watermark anti-counterfeiting paper process is relatively complicated and the cost is too high;
[0004] 2. The production batch of papermaking needs to be large. Generally, the minimum order quantity needs to be 5 tons, and it is impossible to accept the production of small batches of watermark paper;
[0005] 3. The lead time is as long as 1-2 months

Abstract

The invention relates to the technical field of water printing paper preparation devices and preparation methods, in particular to a white water printing paper preparation machine and a preparation method. White water printing ink permeates paper by stamping to change the light transmittance of the paper, and predetermined white water printing patterns with different brightness are generated during visual inspection of light transmittance, so primary textures and characteristics of the paper are basically not damaged, and any influence on reprinting, writing, printing and the like after printing is not caused.

Description

technical field [0001] The invention relates to the technical field of watermark paper preparation equipment and a preparation method, in particular to a white watermark paper preparation machine and a preparation method. Background technique [0002] The traditional watermark paper is to make the paper produce watermark effect by mechanical means during the papermaking process. When the paper is in a wet state, the density of some fibers is changed by mechanical means to destroy the original composition of the fibers. After the paper is dried, the paper fiber structure changes. The difference in light transmittance of each part will produce a pre-designed watermark pattern. There are two traditional mechanical means: one is to use online forming technology to install a pre-designed specific watermark pattern printing plate on the screen. The second is to use a cylinder with a special engraving pattern to emboss the wet page paper that has just been interwoven with a certai...
