There are two types of edible ins for pharmaceuticals

• 1. KOELINK SB is shellac based in solvent medium
• 2. KOELINK WB is shellac based in water medium

For curing the ink, as such there is no particular method to cure the ink but air drying is the recommended curing method. The addition of mixed solvent may be required to maintain a viscosity appropriate for the application method.

The cleaner or water are recommended for removing excess ink from the printing equipment. To remove dried ink deposits, a strong alkali such as Tri Sodium Phosphate is suggested, parts must be thoroughly rinsed with water after cleaning.
