Aquatint is an etching technique that results in a watercolour effect.
Resin particles are either dusted or applied directly onto a metal plate. The metal plate is then heated to allow for the resin to melt and fuse onto the plate. The solidified resin forms a porous protective ground that, upon contact with an acid, results in tiny grooves around the melted resin particles capable of holding low viscosity ink. The resin can be dusted either by hand or by using a dust-box for a more even effect.
A la poupée
The Drypoint technique is a variant of engraving where a line is traced on the matrix using a sharp tool such as those mentioned in the “engraving” term.
The tool is held like a pencil, which displaces a “burr” on the sides of the line. The burr can hold ink and produces a rich “feathered” effect when printed. The burr is a very thin sliver of the matrix material and naturally it cannot withstand the repeated passes through a printing press, resulting in very few prints that feature the distinctive rich drypoint line.
The total number of final prints, usually numbered 1,2,3… followed by a “/” slash and then the total number of prints in the edition.
Stages or States
Parts of the shape can be protected at various stages during the etching process using a ground before submerging into an acid bath. The intent is to create different tones or highlights.
