ABSTRACT:
According to this invention, a broad stock sheet is prepared and subjected preparatorily to degreasing and cleaning treatments. Then, a series of desired patterns are provided on the stock sheet by the transfer printing or screen printing technique with a color ink paste containing dyestuff or pigment color and resin binder and then the printed patterns are heat set. The stock is chemically or electro-chemically plated with a metal layer, with exception of the printed and baked patterns. Punching is made for separating final products from the stock sheet, either before execution of the said printing step or after the said final plating step.
