LED-UV becomes increasingly important. This technology combines all advantages of traditional UV printing; however - compared to conventional lamps - without the emission of ozone or the use of mercury vapor lamps. Overprint varnishes are indispensable in LED-UV printing, too. They finish printed products with valuable visual effects and differentiate the brand from competition.
Whether stamping, high gloss or matt, drip off, partially applied or full area – LED-UV coatings offer printers the possibility to “set apart from the crowd”.
Currently used UV varnishes, adjusted to the spectrum of conventional UV lamps, are not suitable to be used in LED-UV printing. New developments and their photoinitiators must consider the narrow wavelength definition of LED-UV technology. Apart from their visual effects, LED-UV coatings offer a good processing. They show a high reactivity and a good flow-out; they are scuff resistant and enable clear and high-contrast printing images.

Our LED-UV coatings provide many advantages. Make sure to ask for LED-UV products if you work with this technology.

Advantages of LED-UV coatings
Finishing:
LED-UV coatings are far more than protection.
They provide graphic image enhancement and differentiate the brand from competition.
They offer printers the possibility to “set apart from the crowd”.
Technical Properties:
LED-UV coatings are easy to process.
They are highly reactive, mechanical resistant and show a good flow-out.
They enable clear and high-contrast printing images.
Environmental Facts:
LED-UV coatings forego anti-set-off powders (less cleaning, better working conditions).
They provide immediate curing despite low radiant energy.
Their application is emission-free (ozone).
