ABSTRACT:
A large sized screen plate of a metal mask type for use in printing a conductor on a thick-film-circuit substrate and the like. This metal screen comprises a metal pattern layer with pattern openings corresponding to patterns to be printed and a mesh layer made with fine metal mesh members or wires which are integrally formed on one surface of the metal pattern layer. A pattern opening corresponding to wide pattern lines to be printed is provided with the mesh layer thereover and another pattern opening corresponding to narrow pattern lines to be printed is free of the mesh layer. The metal screen thus formed enables printing of fine lines having a minimum width of 40 microns.
