Abstract

The invention relates to a roll type printing method capable of simulating optical laser stamping, as well as a printed product thereof, which is used in combination with a roll type automatic printing machine. The method comprises the following steps: firstly attaching a layer of partial hot stamping tin foil on an end surface of the printed material by way of cold flatting technique, followed by coloring to form a normal printed coloring layer, wherein the hot stamping tin foil may alternatively be coated with each color ink to form a random color, afterward, further coating a clear polishing paint layer of a proper quantity on the printed coloring layer, and finally pressing recess imprint, which is similar to the optical layer film pattern, on the end surface of the clear polishing paint layer through flexible transfer technique in combination with an optical laser film. Accordingly, with brilliance of host stamping tin foil and different colors of the printed coloring layer, an expected printing effect can be obtained through the clear polishing paint layer and light and shadow refraction effect of its imprint.

Description

Rolling type simulation method for printing optical laser printing and printing products thereof

The invention relates to a printing method of a roulette type analog optical laser printing pattern and a printed product thereof, in more detail, in particular, a color can be applied to the hot stamping tin foil without any additional fitting. In the case of an optical laser film, the novel invention of optical laser printing is also exhibited.

According to the second figure, in the conventional printing process, if a print is to exhibit the special printing effect of the optical laser print, it is first attached to the end face of a printed material 10 (such as paper). Firstly and comprehensively adhering a layer of tin foil 11 which is a metallic bright surface, and the tin foil 11 can be a single color with glare visual effects such as gold, silver, red, blue, yellow, green, etc., and then The end surface of the tin foil material 11 is coated with a white lacquer layer 12, and by the color gamut concentration (ie, thick, light, deep, and shallow) of the white lacquer, the localized or regional "hot stamping" portion is presented. In the deeper part of the white lacquer layer 12, the color of the tin foil 11 will be largely covered, while the shallower part will be less covered, thereby exhibiting a local or regional "hot stamping" effect. Then, a general coloring process is performed on the white lacquer layer 12 to print the main printing contents such as characters, patterns, patterns, colors, and the like, thereby forming a so-called printing color layer 13, and in the printing color layer 13 On top of it will be coated with a layer of gold oil 14 to obtain color protection and increase Utility, Finally, a layer of adhesive on top of the optical laser film gold reservoir 1415 and completion.

Of course, the optical laser film 15 widely sold on the market has a specific Special pattern patterns (such as star-shaped light pattern, logic light pattern, strip light pattern, ring-shaped light pattern, etc.), so that it can be combined with the brilliance of tin foil material 11 to display a unique visual effect.

However, although these printing techniques have been used for many years, they can indeed exhibit special visual effects different from those of general printing. However, if we further explore them, we will find that there are still several deficiencies that need to be improved; for example, The single color of the tin foil 11 is selected from the beginning and can no longer be changed or subjected to multi-color gradation treatment, so that it will be boring, and it must be fully attached to the tin foil 11 and optical. The laser film 15 can exhibit so-called optical laser visual effects, and there are inevitable doubts about excessive waste of resources.

Therefore, in view of the above facts, the inventors have actively invested in R&D and innovation based on their practical experience in practicing the industry for many years. The invention has been published early; therefore, it mainly hopes to have more streamlined resources and printing steps. In order to achieve the same printing effect as desired, and at the same time, it is more desirable to display the changing colors to enhance the different levels and feelings of the visual, thereby improving the printing technology and quality, and providing better printing products to the consumers. It is the main purpose of the invention.

Therefore, it is matched with the automatic printing machine of the coil type, and a layer of local hot stamping tin foil is first adhered to the end surface of the printed material by cold-blowing technology, and then colored to form a general printing color layer. In particular, the hot stamping tin foil can also be coated. The ink of each color is made into an arbitrary color, and then an appropriate amount of gold oil layer is coated on the printing color layer, and finally the optical printing film is matched with the optical laser film to make it be the same on the end face of the gold oil layer. The concave print marks of the optical laser film pattern are characteristic.

First: a partial enlarged view of a printed product made in accordance with the process of the present invention intention.

The second picture: a partial enlarged schematic view of the printed product made according to the traditional process.

In order to further understand the technical means and features of the present invention, the drawings are detailed in the following: as shown in the first figure, a partial enlarged schematic view of a printed product according to the process of the present invention, as shown in the figure The utility model relates to a rotary automatic printing machine (not shown), which firstly adheres a layer of partial hot stamping tin foil 30 to the end surface of the printed material 20 by cold-blowing technology, and then colors it to form a general printing color layer 40, especially The bronzing foil 30 is also partially or completely coated with various colors of ink to make any color. Thereafter, an appropriate amount of the gold oil layer 50 is coated on the printing layer 40, and finally the soft transfer technology is used. The optical laser film (not shown) is formed by pressing the concave print mark 52 of the optical laser film pattern on the end surface of the gold oil layer 50, and the color layer 40 is printed by the brightness of the bronzing foil 30. The various colors, and then the light and shadow refraction effect of the gold oil layer 50 and its depressed print 52, are characterized by the desired printing effect.

The aforementioned so-called reel type automatic printing machine is a basic existing printing device, and because it is used to make the printed material 20 into a bundle shape, and enters the printing machine in a full-sheet continuous conveying mode, it is called a printing operation. It is a "rolling type" automatic printing machine.

Furthermore, the distribution and depth of the depressed impressions 52 depend on the pattern of the optical laser film. It is known that the optical laser films are a film-like product on which various patterns (such as stars) are printed. Dot-like light, logic light, strip light, ring light, etc.), therefore, when the pattern is slightly convex, the invention is pressed by the soft transfer technique After referring to the gold oil layer 50, the gold oil layer 50 will simultaneously form corresponding concave impressions according to the pattern and the depth of the pattern. 52. In particular, the optical laser film can be repeatedly used again. In other words, the present invention can select an optical laser film of any pattern to be used as a transfer means according to the preference of the client, thereby obtaining the desired optical. Laser prints, but do not waste any optical laser film to achieve the best economic and environmental benefits.

The printed product obtained by the method of the present invention comprises: a water-absorbing printed material 20, which refers to various materials which can be printed and colored; and a partial hot stamping tin foil 30 which is adhered to the printed material 20 In the above, it is a variety of colors and various patterns; a printing layer 40, printed on the printed material 20 and the bronzing foil 30, according to the formation of the pattern, pattern and color to be printed; a gold layer 50, It is applied over the printing grading layer 40 and is embossed with an embossed impression 52 of the optical laser pattern on the end surface.

Therefore, with the innovative process and technology of the present invention, it can not only apply the coloring step to the hot stamping foil 30, but also obtain various colors or gradient treatments to be obtained, thereby demonstrating the variability and enrichment of the hot stamping foil 30. It is not necessary to adhere to the optical laser film on the printed product, but also can display the visual effect of the expected optical laser print, which proves that the invention has high application and use value.
