1. A direct to mesh screen printer for creating a screen stencil, including:
a frame that holds a pre-stretched mesh in place during application of a jettable emulsion;
a fixture that holds the frame;
a release fluid;
a platen that holds the release fluid against one side of the pre-stretched mesh;
a fluid dispenser that dispenses the release fluid onto the platen or mesh; and
a printer carriage that supports a print head for printing the jettable emulsion on a side of the pre-stretched mesh opposite the platen, wherein the release fluid comprises water and at least one emulsifier that prevents evaporation of the release fluid.
