Mix 1 part of binder thoroughly with 2
parts of ink on a glass plate.
Roll the etching ground evenly onto the
glass plate; fist as a relatively thick layer,
which is used as a reservoir, then as a
thin dry layer. From the glass plate roll
the etching ground onto the copper plate
from all sides and in thin coats.
A glimpse of copper must be visible
through the translucent ground.
The etching ground can now be
hardened 20 minutes in the drying
cabinet and used as a hard ground.
Roll-On Soft Ground
Mix 2 parts of ink with 1 part of binder
thoroughly on a glass plate.
Roll the etching ground evenly onto the
glass plate; first as a relatively thick
layer, which is used as a reservoir, then
as a thin dry layer. From this dry layer
roll the etching ground onto the copper
plate from all sides and in thin coats.
A glimpse of copper must be visible
through the translucent ground.
Leave the plate with the wet ground in
room temperature for 5-10 minutes -
just enough to dry its surface a little. It
will then be suitable for soft ground
etchings.
