Further, cleaning the paper substrate to remove excess varnish after photocuring can ensure fine and clear anti-counterfeiting patterns. Cleaning includes direct water or solvent cleaning, and direct volatilization cleaning with low boiling point and high flash point solvents. The cleaning method also includes spraying water and pressing with a roller to squeeze out water and varnish under pressure. If the cleaning effect is not good at one time, the above process can be repeated. It has been found through experiments that pressurized water and solvents are more likely to take away the uncured varnish in the anti-counterfeiting element, which improves the cleaning efficiency and enhances the cleaning effect. After washing, it can be dried and flattened. The waste liquid or exhaust gas produced by cleaning can be reused after recovery.

Step, therefore, has the technical effect of any embodiment of the first aspect above, and will not be repeated here.

According to a specific embodiment of the present application, the anti-counterfeit element is manufactured by using the anti-counterfeit element manufacturing method. The anti-counterfeiting element can be used for anti-counterfeiting of security paper, banknotes, valuable documents, securities, passports and other anti-counterfeiting documents. Specifically, through a photocurable transparent varnish, after the varnish penetrates into the paper substrate, it can be photocured to form a variable or non-variable anti-counterfeiting pattern, forming a built-in paper substrate, or built into the paper substrate and Security elements that protrude from the surface of the paper substrate.

Among them, the photocuring adopts a projection method, which may specifically be a DLP projection, a spatial light modulator projection, or a single-point beam scanning method. The light curing light source is a UV light source, including UV-LED light source and laser light source. Varnishes contain dyes or pigments that are variable when excited by laser or ultraviolet light. The anti-counterfeiting element formed by photocuring can have three visual effects: transparent, gray scale or color. The anti-counterfeiting element formed by curing forms a transparent visual effect; the anti-counterfeiting element formed by curing is not limited to black and white, and can have a multi-gray-scale visual effect; light curing can form a color pattern, and the color includes different colors and different color depths. Photocuring forms variable anti-counterfeiting graphics, including variable coding information. Variable anti-counterfeiting graphics are not limited to dots, lines and surfaces, and can also form overprint effects with traditional offset printing, gravure printing, screen printing, embossing printing and digital printing. After the varnish penetrates into the inside of the paper substrate, the anti-counterfeiting element is built into the paper substrate. After the anti-counterfeit varnish penetrates into the interior of the paper substrate, it can highlight the surface of the paper substrate, and form protrusions after curing. While having a visual effect, it can also form a certain hand feeling, such as Braille, line or outline hand feeling; after the surface is raised , can obtain enhanced visual effects, similar to the lens effect, the internal graphics and texts have a magnification effect when viewed from the front, and the dynamic movement or switch effect can be achieved when changing the viewing angle. The implementation position is not limited to one or a certain part of the face, but can be implemented on the entire page. In particular, an overall anti-counterfeiting element and effect can be formed at the border of the face. It is not limited to the implementation of papermaking or printing stages.

Specifically, color visual effects can be formed after curing. The color visual effect is the solidification of multiple colors in different areas. There are two variable amounts here, one is the pattern formed by different colors of varnish on the paper, which is variable, and the other is the light-cured pattern that can also be changed. These two patterns can be the same or different. . The varnish can contain different color components, which are placed in the positions where the color needs to be developed, and then cured by light to form a color and shape match, increasing the performance effect and anti-counterfeiting ability; Different color shade effects; or the same amount of varnish, control the exposure time to affect the color shade.

There are three ways to form gray-scale light-curing patterns, which are time change, space change and varnish amount change.

The time change refers to the gray level calibration of the image according to the gray level relationship of the original document of the anti-counterfeiting image. After calibration, use software to set different exposure times for areas with different gray levels, and improve the efficiency and fineness of gray-scale pattern production by adjusting the exposure time and corresponding exposure patterns at the same time.

Spatial variation refers to a method of simulating time variation to change the exposure at different gray levels. First, the original image file is calibrated and divided into different gray scale registration areas. Each area is subdivided to determine the unit exposure/dot. By changing the unit exposure amount/dot density of different grayscale areas, the effect of changing the exposure time is simulated. That is to change the spatial distribution of unit exposure amount/point, and simulate the visual effect of continuous exposure in the form of stepped digital amount.

Control the release amount of varnish, control the release area of varnish, form different or the same release amount of varnish in different areas on the substrate, and use consistent or inconsistent exposure parameters to obtain grayscale patterns of different levels.

After the varnish penetrates into the base material, if the amount of varnish released is increased, it can protrude from the surface of the paper after light curing, and form bulges after curing, which not only has a visual effect, but also forms a certain hand feeling. After the surface is raised, enhanced visual effects can be obtained, similar to the effect of a lens. When viewed from the front, the internal graphics and texts have a magnifying effect, and when the viewing angle is changed, there is a dynamic movement or switching effect. The varnish release area is not limited to a certain position of the anti-counterfeiting element, and can be implemented on the entire page. A border watermark effect is formed at the border of the banknote to obtain an overall anti-counterfeiting element and effect. The varnish release area and graphic design combine to form a par self-check. For example, a new anti-counterfeiting light-transmitting effect with different gray scales can be formed when the negative image and the positive image are printed together. The anti-counterfeiting elements finally formed in the varnish release area can be displayed in the form of watermarks with different light transmission effects, and can also be displayed in the form of windows, with various forms.
