It will not work without a discharge base. We use the Matsui pantone matching system which is about 14 pigments, a clear discharge base, and a discharge agent (powder). If we are printing on lights, we mix the base with pigments without the agent, and if we are printing on darks we mix the agent into the mix. I think that they make an inert base as well, but we just use the discharge base without agent if printing on lights.
