Abstract

The invention relates to a printing method of real-imitation convex and its products, it mainly sticks a layer of optical compound dazzling basement membrane on the material to be printed with hydroscopicity first, and then print the printing pattern of the required every colour with the ink of every colour on this dazzling basement membrane and form and color the printing layer, then make it cooperate with the convex impression die with corresponding pattern real-imitation carved grain, according to implement the off-line convex operation procedure, make this particular pattern have three-dimensional and real-imitation visual effect convex grain and finish; therefore, through the method, the printing product with high real stereoscopic vision effect can be provided for people by matching the external glare effect contained in the glare bottom film with the reflection visual effect between the simulated real engraving lines and the printing ink.

Description

Embossed embossing printing method and products thereof

technical field

The present invention relates to a printing method for realistic embossing and its products, in particular to a printing method capable of presenting realistic three-dimensional visual effects through a special glare base film, a colored printing layer and realistic embossing and engraving. products.

Background technique

In the prior art, embossing products only perform an off-line embossing step on the outline of the printed pattern, so that the pattern is raised on the end surface of the printed material, so that it is declared as a three-dimensional printed product.

However, in fact, although the above-mentioned existing printed products are supplemented with thick and light printing colors on their patterns for the purpose of highlighting the three-dimensional visual effect, the overall peripheral surface of the patterns is still in a flat state. The pattern is indeed embossed on the printed material, but the pattern itself does not have the real concave and convex lines that the flower pattern should have. In other words, the so-called three-dimensional effect of these existing printed products is purely embossing specific pattern parts. However, it fails to truly present the three-dimensional texture that the pattern itself should have, so it gives people a dull and lifeless visual experience.

Contents of the invention

Therefore, the purpose of the present invention is to provide a realistic embossing printing method and its products in order to overcome the above-mentioned defects of the prior art.

To achieve the above object, the present invention adopts the following technical solutions:

The present invention utilizes a special base film with glare visual effects to match printing inks of various colors and its thick and light shadow printing, and then adds embossing molds with corresponding patterns and realistic engravings to create a realistic printing. Embossed 3D print.

The present invention mainly pastes a layer of optical composite glare base film on the water-absorbing material to be printed, and then prints the required printing patterns of various colors on the glare base film to form a colored printing layer. Then use it to cooperate with the embossing mold with realistic embossing pattern with the corresponding pattern, and implement the off-line embossing operation program, so that the specific pattern has a three-dimensional and realistic embossing texture.

A printing method for realistic embossing, comprising the following steps:

Mainly paste a layer of optical composite glare base film on the water-absorbing material to be printed, and then print the required printing patterns of various colors on the glare base film with various inks to form a colored printing layer, and then use It cooperates with a pair of embossing molds with corresponding patterns and embossing embossing patterns, so that the off-line embossing operation program is implemented, so that the specific pattern has a three-dimensional embossing pattern with realistic visual effects.

A product obtained according to the above-mentioned embossing printing method, the printed product includes:

Water-absorbent printed materials refer to various materials that can be printed and colored, and the materials mentioned include paper materials;

Optical composite glare base film, attached to the surface of the printed material, refers to a special metallic luster film in gold or silver, and has gorgeous colored reflection light and shadow;

The color printing layer, including various colors, is printed on the glare base film with ink to form a printing pattern;

Realistic embossing pattern refers to a pair of embossing molds with corresponding patterns and embossing patterns, and an off-line embossing operation procedure is applied to make the specific printed pattern of the colored printing layer have a three-dimensional and realistic visual effect. .

The present invention has the following beneficial effects:

Through the printing method provided by the present invention, the external glare performance contained in the glare base film can be combined with realistic engraving

The reflective visual effect between ink and ink, so as to give people a printed product with a highly realistic three-dimensional visual effect.

Detailed ways

In order to further understand the technical means and features of the present invention, it will be described in detail later in conjunction with the embodiments and accompanying drawings:

As shown in Figures 1 and 2, they are partial plane enlarged schematic diagrams of printed products of the present invention before embossing and after embossing. It mainly pastes a layer of optical composite glare base film 20 on the water-absorbent printed material 10, and then prints the required printing patterns of various colors on the glare base film 20 with various inks to form a colored printing layer. 30, and then use it to cooperate with a pair of embossing molds 40 with corresponding pattern imitation engravings 42, so as to implement the off-line embossing operation program, so that the specific pattern has a three-dimensional and realistic visual effect embossing pattern 50 done.

The printed product obtained by the above method can give people a highly realistic three-dimensional visual effect through the external glare performance contained in the glare base film 20 and the reflective visual effect between the embossed lines 50 and the ink.

The above-mentioned optical composite glare base film 10 is a special metallic luster film in gold or silver, and has gorgeous colored reflection light and shadow. However, these materials are basic and widely used materials, which are well known in all walks of life, and are not the subject of the present invention. Where the characteristic appeal lies, so it will not be described in detail.

Wherein the embossing die 40 is composed of upper and lower dies and corresponding concave and convex imitation engravings 42, and this is also the basic embossing processing mode, so it will not be described in detail.

Comparing the actual printing samples of the present invention and existing embossed products, one can clearly feel the concave and convex lines and their natural undulations of the product provided by the present invention, while on the existing printed product, it is completely flat Therefore, when watching the samples of the present invention from various viewing angles, one can deeply feel the light and shadow on the pattern and the light and dark changes of thick and light colors, which can give people a more vivid and real experience. visual feeling.

In addition, since the pasting and printing procedures of the present invention are closely connected and conveyed in conjunction with special printing machines, the manufacturing process and efficiency are the same as the general printing steps.

In view of the above, the present invention is not only a highly thought-provoking invention obtained by utilizing the laws of nature, but also improves the technology and application of the printing industry invisibly. It has not been seen in similar articles and related publications on the market, and has The practical value and positive benefits of "novelty" and "progress" obviously meet the requirements for patent application, and should be protected by the patent law, so the application is filed according to law.
