Traditional methods of producing printed circuit prototypes require many steps which include photomask generation, application of resist, exposing the resist, developing the resist, etching the copper and stripping the resist. The technique described herein can eliminate the first four steps. There are presently several printed circuit design aid programs specifically intended for personal computers, and these programs allow one to input the actual physical design of the printed circuit board and receive the output from either a dot matrix printer or a plotter. The output to the plotter is intended to be used as the master to produce a photomask, and the printer output is a quick check of the design.
