Photogravure is a process for reproducing a photograph in large editions. It uses gelatin to transfer the image from a black and white negative to a copper plate. The gelatin carries the image because it hardens in proportion to its exposure to light. Areas of the gelatin not exposed stay soft and can be dissolved away in water.

The plating process uses a chemical to fuse all of the different layers of the PCB together. After being cleaned thoroughly, the PCB is bathed in a series of chemicals. Part of this bathing process coats the panel in a micronthick layer of copper, which is deposited over the topmost layer and into the holes that have just been drilled.
