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)
