Description

Technical Field

[0001] The invention relates to the technical field of a method for producing a traffic sign in a spot color digital printing, and in particular to a method for producing a traffic sign in a spot color digital printing. Background Art

[0002] Traffic signs are an important part of road traffic facilities, and their production quality and standards are directly related to the safety and efficiency of road traffic. The traditional method of making traffic signs is to first apply a color base film, and then use a white film to engrave the words on the film. This process has many shortcomings in actual operation:

[0003] Firstly, the traditional process requires a lot of manual operations during the production process, such as pasting the base film, engraving, pasting the film, etc., which is not only time-consuming and labor-intensive, but also inefficient. At the same time, due to the uncontrollability of manual operations, the traffic signs produced often have problems such as uneven colors and different font sizes, which affects the aesthetics and standardization of traffic signs.

[0004] Secondly, some edges of traditional craft engraving films are prone to water ingress and dust adhesion, resulting in unclear images, especially at night or in bad weather conditions, which greatly reduces the recognition of traffic signs and poses a great hidden danger to driving safety. In addition, due to the large amount of reflective film used in traditional production methods, not only does it increase the production cost, but also as a chemical product, reflective film will produce a large amount of VOC (volatile organic compound) gas during the production process, causing certain pollution to the environment.

[0005] Therefore, in order to solve the above technical problems, a method for producing traffic sign spot color digital printing is designed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of the above-mentioned technology and provide a method for producing traffic signs by digital printing with special colors.

[0007] In order to solve the above technical problems, the technical solution provided by the present invention is a method for producing traffic sign spot color digital printing: the first step is computer drawing, using design software to produce traffic sign patterns;

[0008] The second step is printing and UV ink curing. Use a UV digital printer with all traffic special color inks (yellow, red, green, blue, brown, black) and traffic sign special color inks to print on the reflective film. At the same time, turn on the UV lamp to cure the UV ink on the reflective film. The reflective film with the traffic sign pattern printed on it is rolled up using a reel.

[0009] The third step is to cover it with a high-isolation UV transparent protective film. Prepare a roll of high-isolation UV transparent protective film with a thickness of about 0.07mm and a main material of PMMA; use a laminating machine on the printed reflective film, and use a combination of cold and hot lamination to firmly adhere the high-isolation UV transparent protective film to the reflective film.

[0010] The advantages of the present invention compared with the prior art are:

[0011] The traditional production method has been improved, labor has been saved, production efficiency has been high, the picture is beautiful and standard, and the display is clear. The traffic sign panels produced by this process are on the same plane, which solves the problems of unclear pictures caused by water ingress and dust adhesion on some edges of the traditional engraved film, greatly improving the safety of night driving; and reducing the use of reflective film, reducing costs, greatly improving safety and environmental protection, and reducing pollution to the environment; this method uses advanced UV digital printing technology and high-isolation ultraviolet transparent protective film to achieve fast, efficient and environmentally friendly production of traffic signs, greatly improving the safety and aesthetics of traffic signs. DETAILED DESCRIPTION

[0012] The following is a further detailed description of a method for printing and producing traffic signs in spot colors with digital technology according to the present invention in conjunction with an embodiment.

[0013] A method for producing a traffic sign in a spot color digital printing, the first step is to produce a desired traffic sign pattern by computer drawing using design software according to the standards and specifications of the traffic sign, ensuring that the pattern lines are clear and the colors are accurate, meeting the visibility requirements of the traffic sign;

[0014] The second step is printing and UV ink curing.

[0015] (1) Import the prepared traffic sign pattern into the UV digital printer;

[0016] (2) Adjust the printer settings to ensure that all traffic color inks (yellow, red, green, blue, brown, and black) and traffic sign color inks are used for printing;

[0017] (3) Place the reflective film in the UV digital printer and start the printer to print on the reflective film;

[0018] (4) During the printing process, turn on the UV lamp to cure the UV ink on the reflective film. The curing time is adjusted according to the type of ink and the performance of the printer to ensure that the ink is completely cured and improve the adhesion and durability of the pattern;

[0019] (5) Rewinding the reflective film printed with the traffic sign pattern using a reel;

[0020] The third step is to apply a transparent protective film that blocks ultraviolet rays.

[0021] (1) Prepare a roll of high-isolation UV transparent protective film with a thickness of about 0.07 mm and a main material of PMMA;

[0022] (2) Place the protective film flatly on the printed reflective film, making sure there are no bubbles or wrinkles between the protective film and the reflective film;

[0023] (3) Use a laminating machine to firmly adhere the high UV-shielding transparent protective film to the reflective film through a combination of cold and hot lamination. The combination of cold and hot lamination solves the problems that affect the color and brightness of the signboard, and also solves the problem of wrinkling of the protective film by hot lamination with a traditional laminating machine, thereby improving the overall firmness and weather resistance.

[0024] Afterwards, remove the release film from the semi-finished product covered with the protective film, and ensure that it is pasted on the prepared traffic sign base plate without wrinkles.

[0025] The present invention and its embodiments are described above, and such description is not restrictive. What is described in the embodiment is only one of the embodiments of the present invention, and is not actually limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, and without creatively designing methods and embodiments similar to the technical solution, they should all fall within the protection scope of the present invention.
