Abstract (en)
A screen printing stencil is produced chemically by application of a chemical agent 5 to a screen mesh 3 having a stencil-forming layer. The chemical agent 5 is applied dropwise using computer-controlled apparatus. The chemical agent reacts with the stencil-forming agent to harden the stencil in areas which remain upon subsequent wash-out. The stencil so produced can be used for screen printing in the usual way. The method avoids the use of safe lights and actinic radiation. The apparatus used can be a commercially-available apparatus designed for direct application of liquids dropwise to screens mounted in their frames. The stencil-forming layer can be provided using a commercially-available emulsion-coated film or a commercially-available emulsion applied directly to the screen mesh. <IMAGE>
