Abstract
A direct to mesh (DtM) screen printer for creating a screen stencil is provided. The DtM screen printer includes a fixture to hold a frame, which holds a pre-stretched mesh in place during application of a jettable emulsion, a platen having a cavity and an array of holes in a top surface of the platen and is located against one side of the pre-stretched mesh, and a printer carriage supporting a print head for printing the jettable emulsion on a side of the pre-stretched mesh opposite the platen.

A direct to mesh screen printer for creating a screen stencil, including:
- a frame to hold a pre-stretched mesh in place during application of a jettable emulsion;
- a fixture to hold the frame;
- a platen having a cavity and perforated top surface, the cavity holds a release fluid dispensed through holes in the top surface and form a release fluid layer against one side of the pre-stretched mesh;
- a release fluid control system for dispensing the release fluid into the cavity of the platen and form the release fluid layer;
- and
- a printer carriage supporting a print head for printing the jettable emulsion on a side of the pre-stretched mesh opposite the platen.

- placing the frame in the fixture;
- dispensing release fluid into the cavity of the platen such that the release fluid passes through the holes to form a release fluid layer on a top surface of the platen;
- bringing the platen and the mesh together such that the release fluid in the release fluid layer wets an underside of the mesh;
- printing the jettable emulsion on the mesh;
- and
- curing the jettable emulsion using UV radiation.
