SCREEN PRINTING STENCIL PRODUCTION

摘要

A screen printing stencil is produced chemically by application of a chemical agent (4) to a carrier (2) having an image-receiving layer (1). The chemical agent (4) is applied dropwise using a computer-controlled ink-jet printer. The carrier is then brought into contact with a stencil-forming agent (6) on a screen printing mesh (5), whereby the chemical agent reacts with the stencilforming agent to harden the stencil in areas which remain upon subsequent washout. The stencil so produced can be used for screen printing in the usual way. In a variant, the chemical agent reacts with the carrier and excess chemical agent remains to react with the stencil-forming agent. A part of the carrier is thereby incorporated into the stencil improving its profile. The method avoids the use of safe light and actinic radiation.
