Ink technologies

The printing industry uses a wide variety of different inks and varnishes. Eltosch drying equipment is mainly used for drying of conventional inks, water based varnishes and UV-inks / UV-varnishes.

Drying process: conventional offset ink

  • Penetration
  • Oxidative film building

Drying process: water based varnish

  • Penetration
  • Evaporation
  • Physical cross linking of the dispersion binders- drops
  • Precipitation of high molecular acids

Curing process: UV inks

  • Polymerization (radical or cationic)
