Abstract
A stencil plate is made by an electroplating process rather than a steel fabricating process. A resist material and a film were placed upon a matrix and by using conventional photoresist operations, a resist coating is formed on the matrix in the shape of the apertures to be formed in the stencil plate. Metal is electroplated on the upper surface of the matrix and around the shaped resist material forming a stencil plate. Subsequently, another resist coating may be placed over the first plated material and openings are formed in the second resist material. Upon a subsequent plating operation, these openings are filled with a plating material and this provides a color dams structure around the openings in the originally formed stencil plate.
