DirectCure medium pressure lamps produce high radiation between 190 and 220 nm. This stimulates acrylate molecules and directly generates start radicals for the polymerization and crosslinking of acrylate-based printing inks and varnishes.

The use of DirectCure lamps as intermediate or final curing or also for post-curing of prints is the easy way to produce low-migration prints. Suitable curing systems are available.

The migration values achieved with DirectCure are comparable to electronic beam curing.


  1. Achieving food compatibility (migration)
  2. Suitable for applications that could previously only be achieved using EBC (electronic beam curing) = great price advantage for the customer
  3. Simple retrofitting of all existing inert systems
  4. UV systems without inert can also be retrofitted by adding an inert chamber

Highest conversion of double bonds through direct stimulation of the acrylates:

  • Enhancement of chemical and temperature resistance
  • Better light and weathering resistance
  • Crosslinking density higher than with electron beam curing

Very low concentrations (<0.5%) of photo initiators required:

  • Significant reduction in migration and VOC emissions
  • No UV smell
  • Limit values for migration from food packaging can be observed
