Are UV inks used in screen printing?

UV inks for screen printing are cured by ultraviolet rays and are ideal for printing on round surfaces, such as bottles, cups, as well as on objects that are flat and oval or form part of a circle. The inks are cured by inducing chemical polymerisation through the action of UV light. Once cured, the paint acquires a high level of resistance to solvents, grease and moisture. The result is a fairly flexible coating that is resistant to mechanical damage. The most important advantages of UV inks for screen printing are good colour coverage and high adhesion to the substrate.

With UV inks for screen printing, it is possible to achieve print reproducibility regardless of the substrate. Photoinitiators guarantee immediate drying after exposure, which is not insignificant for printing time and costs. The inks are highly efficient and are available in gloss and matte. What is more, the printout created with UV inks is weatherproof.

Application of UV ink for screen printing

UV-curable screen printing inks are ideal for the production of banners, stickers, displays and many different advertising materials that can be exposed to changing weather conditions. In addition, UV inks for screen printing are used for printing on:

- Bottles and jars

- Toys

- Packaging

- Household appliances

Thermoset inks are suitable for printing on polyethylene and polypropylene surfaces as well as on glass, paper, cardboard and self-adhesive films and PVC. In addition, UV inks are suitable for printing on banner materials, for example hard PVC and PVC fabrics, as well as polyolefin films. UV inks for screen printing prove their worth whenever a high yield and high quality multicolour prints are crucial.
