<p>A screen printing assembly attached to a silk screen frame (14) including a support frame (12) positionable adjacent and attachable to the screen frame (14). A squeegee (22) and flood bar (24) assembly deposits and forces ink on and through the screen (27) and onto a substrate disposed adjacent the screen (27). The assembly includes a mechanism (20) movable along the support frame (12) and the screen frame (14) and a flexible sheet (28) is attached to and move with the mechanism (20). The flexible sheet (28) is sealed to the support frame (12), and forms in part a sealed chamber (26) in which the squeegee (22) and flood bar (24) assembly deposits the ink on the screen (27). Solvents can be sprayed into the sealed chamber (26), which then safely contains the solvents so that they do not escape into the atmosphere. An inert gas is injected into the chamber (26) displacing the oxygen in it so that the ink does not dry out as rapidly, and safely maintaining the contained solvent. The squeegee is movable by manual or mechanized means mechanism (20) positioned conveniently outside of the sealed chamber. A method for screen printing using the sealed chamber, and the screen printing produced thereby.</p> |
