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)
