That's exactly right. My first several production items were done that way. All were digital communications/control equipment. The tape used wasn't just for convenience though, it was actually photographed to make the positive film sent to the board house to make the printed circuit boards. There is one color per layer, and also one for the silkscreens and solder masks. I still have the artwork for those old boards, both the positive films and the originals with strips of tape.
