UV varnish curing

JB ColorCure: cold UV varnish curing

With UV varnish curing, printers and converters add extra value to their end product. Not only because of the possibilities and effects that UV varnish offers, such as protective and functional varnish capabilities, from matte to high gloss, to wet-look finishes, but also because V-cured varnishes significantly increase productivity.

UV-cured varnishes do not suffer from changes in pH, viscosity, and temperature. The structure of UV varnish is stable, which reduces the need for cleaning stops. It is also possible to leave the varnishes in the inking chamber after the printing order and continue printing the next day. This results in less production loss due to wash-ups.

Benefits of using UV cured varnishes

  • Maximum gloss level.
  • Full protection of the printing.
  • Extremely high wear and abrasion resistance.
  • Improved water tightness and an increase of the box strength.
  • Ease of use
  • Increased productivity due to fewer wash-ups.
  • Fewer chemicals and solvents.

Challenges of UV varnishes

While UV-cured inks have a lot of benefits, there are also some concerns, such as:

  1. UV varnish migration.
  2. Production of ozone and heat.
  3. Safety.
Safe and efficient cold UV-varnish curing
Cold UV curing, using eco-friendly filtered water technology, prevents ozone formation, a big advantage in food packaging.

Unlike conventional systems that use air to regulate the temperature of the UV lamps, JB ColorCure uses eco-friendly filtered water technology. A major advantage of this is the avoidance of unhealthy ozone.

The lamps of the ColorCure UV system can be adjusted to the width of the box and printed area. ColorCure UV flexo curing is controlled by Sentinel®, an automatic plate detection, and in-press dryer inspection system. If necessary, this monitoring system turns off the UV light in less than one second. To further guarantee safety, ColorCure’s surface always stays below the self-ignition temperature of the paper.
