Problems solved by technology

[0004] However, the Fresnel lens texture is composed of small to large concentric circles. These concentric circles have deeper grooves than the general laser pattern, and cannot be formed by traditional molding methods. That is to say, traditional molding The method cannot form the Fresnel lens pattern on the transfer film

Embodiment 1

[0065] Embodiment 1 The making of transfer film and transfer aluminized paper

[0066] In the present embodiment, the manufacturing method of transfer film comprises the following steps in sequence:

[0067] (1) Make the original model with Fresnel lens pattern and laser graphic pattern, and then electroform to form a molded working plate;

[0068] In step (1), after electroforming, the lines on the original mold are copied to the molded working plate. Correspondingly, the molded working plate has Fresnel lens lines and laser graphic lines; the original mold can also have other lines , such as text texture. The original model is made according to the printing elements required by the customer, and the Fresnel lens, laser graphics, text and other printing elements are put together.

[0069] (2) Install the molded working plate on the molded roller; coat a layer of UV-curable embossing paint on the lower surface of the plastic film, and then make the UV-cured embossed paint co...

Abstract

The invention discloses a method for manufacturing a transfer film. The method comprises the steps of (1) manufacturing a master die with Fresnel lens patterns and laser graph patterns, and then electroforming to form a die-pressing working plate; (2) mounting the die-pressing working plate on a die-pressing roller, coating a layer of ultraviolet curing embossed coating on a lower surface of a plastic film and enabling the ultraviolet curing embossed coating to be closely contacted with the die-pressing roller, and then curing the coating layer; (3) separating the ultraviolet curing embossed coating layer from the die-pressing working plate to obtain a transfer film. A method for manufacturing transfer aluminum-plating paper comprises the follow-up steps on the basis of the transfer film: (4) plating aluminum on the ultraviolet curing embossed coating layer to form an aluminum-plating layer; (5) coating a layer of oil paint on the aluminum-plating layer and then drying; (6) compounding the transfer film with printing paper, and then separating the ultraviolet curing embossed coating layer from the aluminum-plating layer to obtain the transfer aluminum-plating paper. According to the method, clear Fresnel lens patterns and laser graph patterns can be formed on the transfer film and the transfer aluminum-plating paper.

Description

technical field [0001] The invention relates to a printing process, in particular to a method for making a transfer film and a method for making a transfer aluminized paper. Background technique [0002] At present, the application scale of laser graphic packaging materials has gradually expanded, especially on cigarette packs, wine labels and other packaging, and its colorful patterns make people more and more fond of it. Fresnel lens (Fresnel Lens) is a kind of optical element with microstructure. One side of the lens surface is smooth, and the other side is engraved with concentric circles from small to large. It has been used for projection display and car lighting since its invention. , infrared detection and other fields. If the Fresnel lens is combined with the laser graphics, the visual impact of the laser graphics will be stronger, and the grade of the laser graphics packaging materials will be improved. [0003] Traditional laser-graphic packaging materials are g...
