Problems solved by technology

[0002] The current three-dimensional graphics include laser holography, lenticular printing, etc. Laser holographic three-dimensional requires a light source to facilitate viewing, and the three-dimensional image has rainbow reflections, and the definition is not enough. Lenticular printing is limited by the insufficient resolution of the printing machine, so it cannot be used. Thin grating, resulting in insufficient fineness, thicker product thickness, has great shortcomings in application, and the technology has existed for decades, too many people can make it, and it no longer has anti-counterfeiting effect

Embodiment Construction

[0026] Below in conjunction with accompanying drawing and specific embodiment the present invention will be further described,

[0027] A method for making a microlens three-dimensional image and text, the method for making the microlens three-dimensional image and text film comprises the following steps:

[0028] Step 1: Make a microlens array template, calculate the diameter, curvature and magnification of the microlens according to the resolution and the thickness of the transparent substrate, use the engraving equipment to engrave the microlens array on the substrate, and then make the engraved microlens array Containing the nickel master plate of microlens array, engraving equipment can adopt mechanical ultra-fine grinding head to engrave magnifying glass array, comprise diamond or alloy cutter, or adopt high-energy beam to engrave magnifying glass array, present embodiment adopts high-energy beam, such as figure 1 In the laser direct writing technology of the engraving e...

Abstract

The invention discloses lenticule stereoscopic graphics and texts and a making method thereof. The method comprises the following steps of: 1, making a lenticule array template; 2, making a transparent UV mold pressing sleeve; 3, making a relief graphic and text template of a stereoscopic micro structure; 4, carrying out mold pressing on the transparent UV mold pressing sleeve made in the step 2 and the relief graphic and text template of the stereoscopic micro structure made in the step 3 by UV mold pressing equipment with double precisely positioned surfaces; and 5, coating the back surface of the relief graphic and text template of the stereoscopic micro structure of the mold-pressed substrate, wherein the coated substrate is a finished product. The obtained graphics and texts are clear ultrathin multilayer stereoscopic graphics and texts; by adopting the method, multilayer stereoscopic anti-fake products with more advanced stereoscopic anti-fake lines and higher anti-fake grade than the present dollar, won and other bank notes can be made; the method is also suitable for all products requiring high-order visual anti-fake.

Description

technical field [0001] The invention relates to the technical field of visual anti-counterfeiting, in particular to a method for making a microlens three-dimensional image and text and the microlens three-dimensional image and text. Background technique [0002] The current three-dimensional graphics include laser holography, lenticular printing, etc. Laser holographic three-dimensional requires a light source to facilitate viewing, and the three-dimensional image has rainbow reflections, and the definition is not enough. Lenticular printing is limited by the insufficient resolution of the printing machine, so it cannot be used. Thin gratings lead to insufficient fineness, thicker products, and great shortcomings in application. Moreover, the technology has existed for decades, and too many people can make it, so it no longer has the anti-counterfeiting effect. Contents of the invention [0003] Based on the deficiencies of the prior art, the present invention not only pro...
