copper original should be a mirror

Absolutely true! So you have - not the original plate.

Read about the technology of obtaining copies of images on metal. Metal plate coated with a gelatin emulsion, potassium dichromate , and dried in the dark. Then projected onto it using overhead projector image. There, when the light came , gelatin zadublivaetsya . In dark places, it also retains the ability to dissolve in water , and after exposure wash it out , exposing the metal surface. Then poison and if it is copper , the solution of ferric chloride. Etched only where there are dark places. Then removed and zadublennuyu gelatin , and formed after etching deeper rubbing paint - as in etching. Obtained a photocopy (only ...) on the metal.
