An acid-resistant compound that is heated to become liquid, applied
to a warm etching plate, and rolled to a thin, even coating. When
the coated plate is cooled, a hardground is formed. Etching needles
or a variety of other metal instruments can be used to cut through
the ground to expose the metal for etching.
Paper that has been formed from pulp using a hand-held mold, matrix,
or other device.
A trade name for polycarbonate sheet.
An etching technique in which it is possible to draw and print
in positive rather than in reverse. The process consists of drawing
with pen or brush either on an aquatint ground or on a clean copper
plate using a solution of sugar and India ink. After the solution
is dry, the plate is thinly coated with an acid resist, dried
and then immersed in a tray of warm water, which dissolves the
sugar-ink mixture, thereby lifting the resist coating off the
plate. The exposed drawing is then placed in an acid-bath and
prepared for printing
