Sheet-type printing method for simulating frosting and optical laser printing and its printing products

The invention relates to a sheet-type printing method capable of simulating frosting and optical laser printing and a printed product thereof, and more particularly, a method for coating any color on a hot stamping tin foil without additional In the case of fitting an optical laser film, it can also exhibit the novel invention of optical laser printing.

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 sheet-type automatic printing machine, 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 make 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 a proper amount of gold oil and repelling oil are sequentially coated on the printing color layer to form a frosted layer, and finally, a soft printing film is used to match the optical laser film, so that It is characterized by the depression of the same pattern of the optical laser film on the end face of the frosted layer.

First: A partially enlarged schematic view of a printed product produced in accordance with the process of the present invention.

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 following is a detailed description of the following: As shown in the first figure, a partially enlarged schematic view of a printed product according to the process of the present invention is shown in the figure, which is matched with a sheet-type automatic printing machine (not shown) before the printed material 20 The end face is adhered with a layer of local hot stamping tin foil 30 by cold-blowing technology, and then colored to form a general printing color layer 40. In particular, the hot stamping tin foil 30 can also be partially or completely coated with various colors of ink to make any color. Applying an appropriate amount of gold oil and repelling oil to the printing color layer 40 to form a frosted layer 52, and finally using a soft transfer printing technique with an optical laser film (not shown) to make it The depression mark 52 which is the same as the optical laser film pattern is pressed out on the end surface of the frosted layer 50, and the color of the stamping layer 40 is matched by the brightness of the stamping tin foil 30, and then the frosted layer 50 and the depressed impression 52 thereof are transmitted. The light and shadow refraction effect is characterized by the expected printing effect.

The aforementioned so-called sheet-type automatic printing machine is a basic existing printing device, and because it is used to make the printing material 20 enter the printing machine in a single piece of printing mode, it is called a "page type". 』Automatic printing equipment. As for the use of gold oil mixed with oil to make the undulating undulating printing surface, which is commonly known as the "matte" printing surface layer (depending on the particle size, which can also be called the ice-printed surface layer), it is a skill, for the industry. It is not well known to the members and is not a feature of the invention. Therefore, the inventor will not repeat them. I would like to examine them.

Furthermore, the distribution and depth of the depressed impression 52 are the pattern of the optical laser film. However, it is well known that these optical laser films are a film-like product on which various patterns (such as star-shaped light, logic light, strip light, ring light, etc.) are printed. Etc.), therefore, when the frosted layer 50 referred to in the present invention is pressed by the soft transfer printing technique with the slightly convex pattern surface, the frosted layer 50 will follow the pattern and the depth Synchronizing to form corresponding concave impressions 52, in particular, the optical laser film can be repeatedly used again. In other words, the present invention applies an optical laser film of any pattern to the transfer means by visually selecting the client.俾 To obtain the required optical laser prints, but without wasting 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 can be used in various colors and various patterns; a printing color layer 40 is printed on the printed material 20 and the bronzing tin foil 30 to form a pattern, a pattern and a color to be printed; a frosted layer 50, Gold oil and repellent oil are sequentially applied to the printing color layer 40, and the concave laser marks 52 of the optical laser pattern are imprinted on the end faces.

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.

Looking at the above, the present invention is not only high in the use of natural laws. In addition to the intangible creation of technology and application in the printing industry, in addition to not being found in similar products and related publications, it has already possessed the practical value and positive benefits of "newness" and "progress". The application requirements should be protected by the patent law and submitted in accordance with the law.
