What are UV Curing System and Its Benefits?

Posted by Alpna Visual on June 17th, 2019

UV Curing is an important drying technique which is used for perfect printing on luxury materials. UV Curing involves a photochemical procedure using high-intensity UV ray of light to cure or dry inks, adhesives, and coatings instantly. This procedure is advantageous to decrease reject rates, increase the speed of production, then the traditional drying procedure and facilitate a high-quality bonding to improve scratch and solvent resistance. You can choose the best UV Curing System Manufacturers to increase productivity and high-quality printing.

Working Procedure of UV Curing

The UV Curing procedure is based on photochemical reaction by using light instead of heat. The liquid oligomers and monomers are blended with photo-initiators to expose UV energy. Then, coatings, inks or adhesives all gets harden immediately. This procedure is completely different and advantageous for solvent-based products compared to the traditional method by working of heat and principle of dry air involving solvent evaporation which creates shrinkage and also produces environmental pollutants.

There is no involvement of solvent to evaporate or to decrease of thickness, no decrease in volume and no production of environmental pollutant within the process of UV Curing. This procedure develops the physical properties of your luxury products such as gloss finish, chemical and hardness resistance, better scratch and elasticity and this improvement is advantageous to strengthen the product generally. The UV light, which is used in UV Curing system, comes from a specific portion of the spectrum of light. Generally, ranging from 200 nm to 400 nm wavelength is used in this procedure. The light with this range of wavelength is used in water purification, adhesive curing, and semiconductor lithography.

When the UV lights cure inks, adhesives or coating, it breaks down into two parts. One part is the resin itself and the other part the photo-initiator which is already blended in. When the UV light is delivered, photo-initiator involved chemical reaction to dry ink, adhesive or coating. Screen Printing Machine Manufacturers use the working procedure of UV Curing to get the best quality printing.

Advantages of UV Curing Inks for Screen Printing and Digital Printing

There are several advantages of UV Curing inks for screen printing and digital printing. Some of these advantages are as follows.

• Instant drying of UV Curing inks help prints get ready and cured instantly after printing and it helps to increase production speed.
• It helps in a high amount of production with less amount of maintenance as it reacts only with UV light.
• It doesn’t involve any solvent, so the amount of ink is colourant. They are used on the surface without absorbing by pores present on the materials. You can get an intense colour for printing by using less amount of ink and it is cost-effective.
• Cross-linked molecules of UV ink offers durability.
• UV inks are eco-friendly and they don’t produce any air pollutant.

Application of UV inks for Screen Printing

UV inks are applied for printing on smooth surfaces. Screen Printing Machine Manufacturers follows the technology of UV Curing procedure to get several benefits. Generally, UV inks are used in screen printing for nameplates, decals, CDs, Signage, metal decoration, automotive artwork, and container decoration. UV inks are available as glitter inks. It helps to make prints which are attracted by magnets. The owners of screen printing business get many opportunities when they provide printing services by using UV inks.

Summary

If you want to upgrade your screen printing services, you can include a UV Curing system supplied by the best UV Curing System Manufacturers and get all of the above-mentioned benefits.
