Carbon tissues are mixed with the light-sensitive DAS (diazostilbene) chemical, poured onto a synthetic paper substrate and left to dry in the dark.
The copper plate is covered with a layor of aquatint resin dust inside an aquatint box.
The aquatint is melted onto the surface of the copper plate using an alcohol burner or by heating the plate in an oven.
A photographic positive is prepared from a negative.
The photographic positive is placed onto the prepared carbon tissue.
The carbon tissue is exposed to ultraviolet light.
The carbon tissue is coupled to the copper plate in a bath of cold water and left to sit under weights for 30 minutes. It is then developed in a bath of hot water to melt away any unexposed gelatin in the carbon tissue. After development, the plate is left to dry over night.
The copper plate with the carbon tissue layer is etched in a baths of various dilutions of ferric chloride.
The plate is then washed and the carbon tissue layer is washed away. The plate is dried with a fan.
The dry copper plate is covered with etching ink.
The ink is then wiped from the copper plate with tarlatan cloth.
A piece of printing paper is moistened in a bath of water. The paper is then blotted dry and placed in the printing press with the inked copper plate.
The paper and plate are run through the printing press under high press and the paper is removed from the press to reveal the printed image.
