According to one embodiment of the present application, the security element is manufactured by a method for manufacturing the security element. The anti-counterfeiting element can be used for anti-counterfeiting of security papers, banknotes, valuable documents, securities, passports and other anti-counterfeiting documents. Specifically, after penetrating into the paper substrate, the light oil is photo-cured to form a variable or non-variable anti-counterfeiting pattern, so that an anti-counterfeiting element which is built in the paper substrate or is built in the paper substrate and protrudes out of the surface of the paper substrate is formed.
The light curing adopts a projection mode, and can be specifically DLP projection, spatial light modulator projection and single-point light beam scanning modes. The light curing light source is a UV light source, including a UV-LED light source and a laser light source. The gloss oil contains a dye or pigment which is changeable under the excitation of laser or ultraviolet light. The anti-counterfeiting element formed by photo-curing can have three visual effects of transparency, gray scale or color. The anti-counterfeiting element formed by curing forms a transparent visual effect; the anti-counterfeiting element formed by solidification is not limited to black and white, and can have a multi-gray-level visual effect; the photo-curing can form a color pattern, and the colors comprise different colors and different color shades.

The variable anti-counterfeiting image-text is not limited to points, lines and surfaces, and can also form overprinting effect with traditional offset printing, gravure printing, silk screen, letterpress printing and digital printing. After the gloss oil permeates into the paper substrate, the anti-counterfeiting element is arranged in the paper substrate. After penetrating into the paper substrate, the anti-counterfeiting gloss oil can protrude out of the surface of the paper substrate, and after solidification, bulges are formed, so that the anti-counterfeiting gloss oil has a visual effect and a certain hand feeling, and can form braille hand feeling, line hand feeling or outline hand feeling; after the surface is raised, a reinforced visual effect similar to a lens effect can be obtained, the internal image and text has an amplifying effect when being observed in the front, and the changing observation angle has a dynamic movement or switching effect. The application position is not limited to one or a certain part of the ticket face, and the ticket face can be applied in a whole mode, and in particular, the whole anti-counterfeiting element and effect can be formed at the ticket face frame. Not limited to paper making or printing stages.
Specifically, a color visual effect can be formed after curing. The color visual effect is that multiple colors of different areas solidify. There are two variable amounts, one is the pattern of different color gloss oils on the paper, the other is the photo-cured pattern, both of which can be identical or different. The gloss oil can contain different color components, and is subjected to photo-curing after being respectively placed at the positions needing color development to form color and shape matching, so that the expression effect and the anti-counterfeiting capacity are improved; or the same gloss oil quantity is different, and different color shade effects are formed after photo-curing; or the same amount of gloss oil, the exposure time is controlled to influence the color shade.
There are three ways of gray-scale photo-curing pattern formation, time variation, space variation and gloss oil amount variation, respectively.
The time change refers to the gray scale calibration of the image according to the gray scale relation of the original file of the anti-counterfeiting image. After calibration, different exposure time is set for areas with different gray levels by using software, and the efficiency and fineness of gray pattern manufacturing are improved by adjusting the exposure time and the corresponding exposure pattern at the same time.
Spatial variation refers to a method of varying the exposure at different gray scales by simulating temporal variation. First, the original image file is calibrated and divided into different gray scale registration areas. Each region is subdivided to determine the unit exposure/point. The effect of changing the exposure time period is simulated by changing the unit exposure amount/dot density of different gray scale areas. I.e. changing the spatial distribution of the unit exposures/spots, in the form of a step number, simulating the visual effect of a continuous exposure.
And controlling the release amount of the gloss oil, controlling the release areas of the gloss oil, forming different areas or the same release amount of the gloss oil on the substrate, and obtaining gray patterns with different grades by using consistent or inconsistent exposure parameters.
After the gloss oil permeates into the base material, if the release amount of the gloss oil is increased, the gloss oil can protrude out of the surface of the paper after photo-curing, and after curing, bulges are formed, so that the gloss oil has a visual effect and simultaneously a certain handfeel. After the surface is raised, a reinforced visual effect similar to a lens effect can be obtained, the internal image and text has an amplifying effect when being observed in the front, and the changing observation angle has a dynamic movement or switching effect. The gloss oil release area is not limited to a certain position of the security element and may be implemented in full-scale. And forming a frame watermark effect at the ticket face frame to obtain the integral anti-counterfeiting element and effect. And combining the gloss oil release area with the graphic design to form the ticket face self-check. For example, the negative image and the positive image are printed with new anti-fake light transmission effects with different gray scales. The finally formed anti-counterfeiting element in the gloss oil release area can be displayed in the form of different light transmission effects of watermarks, and can be displayed in the form of a window, so that the forms are diversified.
