The viscosity of the Ferric Chloride controls the speed with which the solution penetrates the gelatin. Methods. One method of photoengraving produces a shallow depression in the is used for intaglio printing plates or for decorative purposes.
It is also the same method used for printed circuit engraving is usually made in copper or process can be done in open trays but is much more effective if the etchant (often ferric chloride) is sprayed onto the metal.

Each period has its own view of the human figure. The viscosity of the Ferric Chloride controls the speed with which the solution penetrates the gelatin. The result is a plate with many minute reservoirs or cells of varying depths.
During printing, the deeper cells hold more ink and thus transfer more ink to the paper, creating the darker areas of the Rating: % positive.

Copper is more readily attacked by ferric chloride (iron chloride), which is commonly used in concentrations of 28–45 percent. The etching may be done in an open tub or tray, though this method does not give the control needed for economical operation and is employed only where control is not critical.
A typical aqueous etching solution for magnesium and zinc contains between 10 and 20 percent nitric acid, percent urea derivatives, and 1 percent surfactant which is composed of sulfates and alkyl benzenes.
Aqueous solutions of ferric chloride and hydrochloric acid are typically used for copper etching. Taken from the book 'Achievement in [photo-engraving and] letter press printing.

Author Schaffert, R. The etching of the copper is begun by sprinkling it with a solution of ferric chloride, which attacks the metal in the areas where the gelatin is totally dissolved and bites into it more or less deeply depending on the thickness of the surviving gelatin that it must penetrate.

The etching solution (ferric chloride solution) can be either poured onto the rotating copper cylinder or placed in an etching machine that allows the cylinder to rotate constantly in a bath of acid.
