PRINTING SCREEN SEALING SYSTEM

摘要

A system providing a seal between an inner rim of a support frame (202, 302) and a screen (204, 304) supported by the support frame (202, 302). A bead of flow dam material (216, 218, 316, 318) is applied at the juncture of the inner rim of the support frame and the screen. The flow dam material seals to the inner rim and to the printing screen. The flow dam material comprises a material which is semiliquid upon application and cures to form a bead of resilient material that does not dissolve in the presence of inks and solvents used in printing and reclamation.
