✨ How to Mix Metallic & Pearlescent Colors:
When printing gold, silver, or pearl effects, use 901 Gold Varnish. Mix with approx. 10% Metallic/Pearl Powder (must be ≥1200 mesh) and add 2% SD-Dot Paste to prevent pigment settling and separation. Note: Mixed metallic ink should be consumed within one week.
Usage & Curing Instructions
Thinning & Preparation
Stir well before use. If viscosity is too high, add 5-8% UV-SL Thinner. Do not over-thin, as it may reduce curing speed and compromise hardness.
Mesh & Squeegee
Crucial: Use a high-density screen of ≥420 mesh/inch and a ≥75° squeegee. Thick ink layers will fail to cure completely, destroying adhesion and wear resistance.
Hardener for Max Water Resistance
To achieve absolute maximum water and chemical resistance, add 5-8% of B-11 Hardener. Peak resistance is reached 1 week after printing. (Use mixed ink within 8 hours).
Multi-Layer Overprinting
When printing multiple layers, reduce the UV intensity for the base color. Over-curing the bottom layer will reject the adhesion of the top layer.
