Problems solved by technology

[0004] 1) Glitter powder is very light because it is made of PET film; when workers are working, it is easy to cause powder particles to fly in the production workshop, workers only wear masks to work, and the environmental conditions are very poor;
[0005] 2) The powder needs to be adhered to the printed matter with the glue coated in advance. Since it is completed in two processes, the adhesion is greatly reduced, and it is easy to fall off by hand, causing two pollutions;
[0006] 3) This process is completed manually or semi-manually, the efficiency is very low, and it is not suitable for the conditions of large-scale programmed mass production

Abstract

The invention discloses a glitter powder silk-screen printing process. The litter powder silk-screen printing process is characterized by comprising the following steps that S1, a silk-screen printing plate is manufactured; S2, the manufactured silk-screen printing plate and a scraping cutter are installed on a silk-screen printing device, the scraping cutter is a 75-degree scraping cutter, and polishing is carried out to form a circular bead; S3, ultraviolet light polymerization printing ink is added to conduct printing, the scraping cutter is used for forming a silk-screen printing ink layer on a printed material, wherein the ultraviolet light polymerization printing ink is a mixture of crystal oil and glitter powder, the inclining angle of the scraping cutter during printing is 45 degrees to 80 degrees, and the printing pressure is 8 N to 20 N; and S4, ultraviolet light with the wave length being 360 nm to 420 nm is used for irradiating the silk-screen printing ink layer, the silk-screen printing ink layer on the printed material solidifies, and the printing ink printing layer is formed. By means of the printing process, waste of the glitter powder is reduced, the production cost is reduced, and in-batch large-scale production can be formed; and meanwhile, the printing process avoids particle pollution and achieves environmental protection.

Description

technical field [0001] The invention relates to the technical field of printing technology, in particular to a screen printing technology of glitter vermicelli. Background technique [0002] Colorful powder (commonly known as glitter powder) is composed of various colored or illusion thin films. It is generally used in festive scenes and various wedding dresses. It sparkles and shines in the sun, which is really eye-catching! In recent years, it has also been used in the printing field, such as using it on some toy packaging patterns or in clothing printing patterns. Its luxurious and dazzling colors are also popular among users, especially children. [0003] However, the colorful powder process currently applied to printed matter mainly uses artificial color powder to sprinkle on the printed matter, relying on the glue coated in advance on the printed matter to make it adsorb or use a powder circulation machine to spray it on the printed matter. The flaws in its workmanshi...
