Description

Digital printing heat transfer printing film

Technical Field

The utility model mainly relates to a heat-transfer seal preparation technical field especially relates to a digital printing heat-transfer die.

Background

The digital thermal transfer printing technology is a new technology for printing color images and patterns in a plateless form by combining the traditional thermal transfer printing technology with the digital printing technology. It is a technological process of pre-printing pattern or characters on base film and transferring the printed pattern and characters to the printed matter under the action of heat and pressure.

Many enterprises are still using the traditional thermal transfer printing technology to deal with the problem of surface decoration, but the thermal transfer printing technology cannot achieve perfect transition of all colors according to the content of pictures, so that the printed effect only presents a clear color boundary. In the middle of two colors, it is difficult to represent the transition of colors according to the picture itself.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides a digital printing heat transfer film, which comprises a base material film 1, a release layer 2, a digital printing ink layer 3, a white ink layer 4, a holographic anti-counterfeiting gold stamping layer 5 and an adhesive layer 6 which are arranged from top to bottom in sequence,

the digital printing ink layer 3 is provided with two layers.

Preferably, the substrate film 1 is a PET film.

Preferably, the release layer 2 is made of a release agent filled in a metal spray can.

Preferably, the lower layer of the digital printing ink layer 3 is high transparency ink 33, and the upper layer of the digital printing ink layer 2 is low transparency ink 32.

Preferably, the adhesive layer 6 is made by coating hot melt adhesive.

The utility model has the advantages that: the process is simple, the efficiency is high, a mold does not need to be manufactured, and the pattern can be directly output; the hand touches the high-definition printed patterns, can feel the oil layer of the patterns, can perfectly transit the colors between the two colors, and has better texture; meanwhile, the holographic anti-counterfeiting gold stamping layer has a unique anti-counterfeiting function, and a consumer can judge the authenticity of the commodity by identifying characters and patterns of the holographic anti-counterfeiting gold stamping layer.

Detailed Description

In order to make the technical solutions of the present invention better understood and make the above features, objects, and advantages of the present invention more comprehensible, the present invention is further described with reference to the following examples. The examples are intended to illustrate the invention only and are not intended to limit the scope of the invention.

As shown in figure 1, the utility model comprises a substrate film 1, a release layer 2, a digital printing ink layer 3, a white ink layer 4, a holographic anti-counterfeiting gold stamping layer 5 and an adhesive layer 6 which are arranged from top to bottom in sequence,

the digital printing ink layer 3 is provided with two layers.

In this embodiment, the base film 1 is preferably a PET film.

By adopting the structure, the PET film has the characteristics of good dimensional stability, uniform tension, good heat-resisting effect and good release property.

In the present embodiment, the release layer 2 is preferably made of a release agent filled in a metal spray can.

The structure has good wear resistance, plays roles in protecting color ink, reducing the radiation intensity of ultraviolet rays, reducing the invasion of adverse factors in air to the ink and prolonging the service life of the ink, and can buffer the adhesive force of a substrate film and a printing layer.

In this embodiment, the lower layer of the digital printing ink layer 3 is preferably a high transparency ink 33, and the upper layer of the digital printing ink layer 2 is preferably a low transparency ink 32.

The arrangement of the structure can enhance the layering sense of printed patterns.

In this embodiment, the adhesive layer 6 is preferably made of hot melt adhesive.

By adopting the structure, after the coated hot melt adhesive is dried into a film, the surface of the holographic anti-counterfeiting hot-stamping layer has excellent composite fastness and flexibility, strong capacities of resisting abrasion, water, acid, alkali and other media and good weather resistance.

Printing twice through the digital printing ink layer, namely printing the ink with high lightness, printing the ink with low lightness, and printing a layer of white ink. The opaque white ink has the function of covering the color of the printing stock, so that the image-text gradation and the color tone transferred to the colored object are not affected.

The holographic anti-counterfeiting gold stamping layer has a unique anti-counterfeiting function, and a consumer can judge the authenticity of a commodity by identifying characters and patterns of the holographic anti-counterfeiting gold stamping layer.

The above-described embodiments are merely illustrative of the principles and utilities of the present patent application and are not intended to limit the present patent application. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of this patent application. Accordingly, it is intended that all equivalent modifications or changes which can be made by those skilled in the art without departing from the spirit and technical concepts disclosed in the present application shall be covered by the claims of this patent application.
