Manufacturing method for hot-stamped and transferred film with Fresnel lens visual effect

Abstract

The invention discloses a manufacturing method for a hot-stamped and transferred film with a Fresnel lens visual effect. The manufacturing method includes the steps that firstly, a lens gray scale pattern is manufactured; secondly, a control computer is used for reading each concentric circle gray scale of the gray scale pattern, and the output power of a high-energy light beam is set to be a laser which outputs different kinds of power according to control of a waveform generation circuit; thirdly, the circumference of each circle is calculated through the computer, and the circumferences are converted into stepping numbers of a rotation platform till the gray scale pattern designed in the second step is completed; fourthly, a photographic plate obtained after photoetching is subjected to developing, and etched lines are developed; fifthly, a photoetching plate is copied into a plate capable of being used for die pressing; sixthly, the die pressing plate is loaded on a die press to be subjected to die pressing; and seventhly, the plate obtained after die pressing is made into a coating film. By means of the method, the unique, effective and visual three-dimensional image-text film can be manufactured and used for achieving fake preventing of currencies, negotiable securities and products and achieving a visual impact effect of printed products.

Description

technical field [0001] The invention relates to the technical field of new materials, in particular to a method for manufacturing hot stamping and transfer films with Fresnel lens visual effects. Background technique [0002] The existing Fresnel lenses are all designed as optical lenses, and its texture structure gradually deepens from the center of the lens to the outer edge. In order to obtain sufficient magnification, the depth of the outer edge of this lens is at least 5 microns, or even Reaches tens of microns, and in order to achieve good optical properties, I like to use a diamond knife to cut a smooth mirror-like effect, but as a hot stamping and transfer film, due to the thickness limit of the layer, the traditional cutting template cannot be used because the texture is too deep The soft layer that needs to copy the texture will be too thick. During the bronzing or transfer process, the cut surface will be uneven, which will affect printing and processing. At the s...

[0002] The existing Fresnel lenses are all designed as optical lenses, and its texture structure gradually deepens from the center of the lens to the outer edge. In order to obtain sufficient magnification, the depth of the outer edge of this lens is at least 5 microns, or even Reaches tens of microns, and in order to achieve good optical properties, I like to use a diamond knife to cut a smooth mirror-like effect, but as a hot stamping and transfer film, due to the thickness limit of the layer, the traditional cutting template cannot be used because the texture is too deep The soft layer that needs to copy the texture will be too thick. During the bronzing or transfer process, the cut surface will be uneven, which will affect printing and processing. At the same time, because the layer is relatively late, the cost of mass production is too high, and the possibility of a large number of applications is lost.
