Topaz solution is a solvent based primer designed to be applied via screen printing on plastic sheets to make them print compatible with Indigo technology.
Topaz is applied via silk-screen printing technology on untreated plastic film and sheets. The recommended dry coat weight is approximately 1.9 g/m2. Make sure all equipment is adequately cleaned and that no residue from other materials is present. Use our Topaz Indicator solution to check quality of the coating. Cleaning only with iso or n-propanol is recommended.
