UV vs. UV-LED ink, What are the differences?

You can print on virtually whatever you want when using UV inks.

Inkjet printing systems have become popular in the past decades because of the constant development of new printing methods as well as techniques that adapt to different materials.

UV inks can be inkjet printed onto a wide variety of porous and non-porous substrates, even metal or glass and are cured almost instantly by a photochemical process in which high-intensity ultraviolet light is used to cure or dry inks (UV curing).

UV inks are exposed to ultra-violet lights as they are printed, immediately turning from a liquid to a solid with very little evaporation of solvents and almost no absorption of the ink into the paper stock.

The development of LED curing technology for UV inks has revolutionized the field of digital printing, opening new opportunities for printing different materials and substrates. LED curing avoids the extreme heat of curing with mercury lamps. Plus LED lamps last longer (and do not have all the mercury of the super-hot style curing systems).

PROS and CONS

  • Limited range of printing substrates
    UV lamps generate high temperatures to cure UV ink; causing paper curling, distortion or heat damage to fragile kinds of media material.
  • Lower ink cost
  • Optimal adhesion without the need for pre-coating
  • Wide range of ink’s, varnish’s and coating’s
  • Used for indoor and outdoor applications for store and point of sale branding, posters, interior design, etc.
  • UV mercury arc lamp operating life is 1,000 hours
  • High energy consumption
  • The The UV mercury arc lamps consumes approximately is 2,005,000 kWh

  • Wide range of printing substrates
    With the UV-LED technology, the temperature is significantly decreased, avoiding overheating the substrate, making possible printing onto many materials that would be vulnerable to hot temperatures
  • Higher ink cost because of special photoinitiator and formulation
  • Optimal adhesion without the need for pre-coating
  • Limited ink’s, varnish and coating’s
  • Used for indoor and outdoor applications for store and point of sale branding, posters, interior design, etc.
  • UV-LED lamp last up to 10,000-15,000 hours.
  • Low energy consumption
  • The UV-LED lamp consumes approximately 950,000 kWh

All these advantages of LED-curing are the reason why companies around the world are gradually switching to LED-curing. Efi VUTEk is the most visible example, since over 80% (or more) of their models use LED-curing.
