摘要：
The novel method comprises (1) producing in one major surface of a metal masking plate an array of substantially-parallel ridges separated by valleys or grooves, (2) removing metal from the other of said major surfaces in generally rectangular-shaped areas opposite the valleys and extending through the plate, (3) covering the tops of the ridges with an electrically-insulating first coating and (4) covering the first coating with an electrically-conducting second coating.
