The Innovative Application of Screen Printing and UV Technology

The basic principle of screen printing is to utilize the screen printing mesh and screen printing frame as the plate base, and make the screen printing plate with graphics through the photographic plate making method. During the printing process, the screen printing ink is squeezed by the screen printing squeegee and transferred to the substrate through the polyester mesh of the graphic part, forming the same graphic as the original.

Screen printing technology has a wide range of applications in the packaging industries of glass, plastic, metal, paper and ceramics. Whether it is flat, curved, spherical, or uneven surfaces, screen printing technology can be easily realized. The thickness of the ink layer after printing can be up to 30μm, giving the printed material a strong tactile and visual impact.

In the glass packaging industry, screen printing is often used in glass containers printed text or patterns; in the plastic packaging industry, screen printing technology is used in the printing of plastic film, to provide protection for the product; screen printing technology is also used in the metal packaging industry because screen printing technology can meet its high requirements for ink adhesion; in addition, the paper packaging industry and the ceramic packaging industry have benefited from the screen printing of the superb craftsmanship.

UV screen printing Ink, as an environmentally friendly ink, has received a lot of attention in the screen printing field in recent years. UV screen printing inks stand out in the printing field with their outstanding characteristics. Their instantaneous curing characteristics allow prints to dry in a short period of time and eliminate the need for volatile solvents, thus realizing environmentally friendly screen printing. In addition, its simple and convenient application greatly improves screen printing efficiency. In screen printing, UV screen printing ink can be adapted to paper, synthetic paper, wood products, plastics and other substrates, showing a wide range of applications.

Let’s talk about the strengths of UV screen printing ink in details. UV screen printing ink curing speed is extremely fast, with the compact size of the UV equipment, making the screen printing production efficiency greatly improved. The characteristics of the ink makes it will not block the screen, and the concentration remains stable, which is very suitable for the pursuit of high quality printing needs. It does not contain volatile solvents, the use of the process on the human body and the environment have no adverse effects, the real realization of green environmental protection. UV screen printing ink is excellent in abrasion resistance, solvent resistance and weather resistance and other properties to ensure that the print is durable.

In the current packaging market, cigarettes, alcohol, cosmetics and food packaging boxes and other areas of extensive use of screen printing UV technology. Gold, silver cardboard UV frosted, UV ice flowers, UV wrinkles, UV refractive and UV gemstone effects, after the UV lamp clever irradiation, will be able to show a colorful, lifelike simulation of artistic effects.

For UV screen printing technology, the best choice of screen printing mesh is 350-450 mesh solvent-resistant screen. We recommend 75-85° polyurethane adhesive screen printing squeegee to get ideal printing effect. When screen printing, the UV screen printing ink should be fully stirred after opening the can. If necessary, UV monomer diluent can be added to adjust the viscosity. The amount of additive control in the range of 0.5-1%. At the same time, the curing process needs to pay attention to the heat performance of the substrate, it is recommended to use low-temperature water-cooled curing machine or water-cooled LED light source. After screen printing, using  general-purpose screen cleaner for cleaning is recommended. In the meantime, overlay Printing Guideline: If overlay screen printing is required, please make sure that the product is not left for more than 24 hours after the first layer of screen printing, and be sure to conduct adhesion and reliability tests.

That is all info about the Innovative application of screen printing and UV technology. Screen printing through the unique mesh structure to achieve accurate printing, widely used in glass, plastic, metal and other packaging industries.UV screen printing ink is environmentally friendly and efficient, instant curing and suitable for a variety of materials, local UV varnish more three-dimensional texture, for packaging design to bring stunning effect.
