Stencil: All types, but we recommend using a Phthalate free emulsion such as DC-521 by Image Mate.

Reducer: 6501 Curable Reducer or 6502 Viscosity Reducer. 6501 Curable Reducer can be used in virtually any quantity, keep in mind it will effect opacity when added in excessive amounts. 6502 Viscosity Reducer should be used in limited quantities of 2-4% by weight. The addition of excessive amounts of 6502 Viscosity Reducer will increase the curing times. Reducers will increase ink flow and help reduce build up. **Please note that inks should be thoroughly stirred prior to printing, inks are thixotropic and will naturally reduce with stirring.
Curing: 6581 Optical White will cure at a temperatures between 300-350F (150- 160C). Thicker ink deposits will require longer curing times. The entire thickness of ink must reach said temperature to achieve a full cure. Tests for product compatibility should always be conducted prior to production runs.
