be etched by simply pressing the felt on the stencil. Larger areas are best
etched by stroking the tool head several times over the entire surface of the
stencil. This takes between 1.5 and 2 seconds. If the etching appears
rusty, then either do not use the tool quite so long or decrease the voltage.
The tool should be held at right angles to the work piece and the whole
surface used for contact with the stencil.

ture wear and tear. When electrolyte vaporises it leaves residues in the
stencil tissue. In time this reduces the clarity of the etching. Dark, i. e. dirty,
felts must be changed frequently and the larger the stencil, the quicker the
felt needs changing.
The results of lettering depend on various factors. The results can vary
depending on material or within a material batch. Test the lettering for
quality on a piece of waste material before beginning to work. The lettering
can usually be optimised by using various parameters and electrolytes. By
using switch (4) you can set whether the lettering should be dark or light.
The result differs with different materials.
More material is removed with light lettering. The stencil gets dirty very
quickly and must be cleaned more often.
5.3.4 the „etching (marking)“ process
• clean the spot to be etched
• cut off 30 mm etching felt (t = 2 mm) from the 60 x 2 x 1000 strip or from
the sheet
• using the „O“- ring, fix the felt pad to the tool head
• using the selector switch (4) set the unit to the desired setting for light
or dark etching
• add enough electrolyte to the felt on the underside of the tool so that it
is wet
• position the stencil in the desired position on the work piece
• using light pressure and small swivelling movements stroke over the
stencil or, if the stencil is small enough to be covered by the tool head,
then simply press down and move slightly to and fro, holding the tool
at right handles to the work piece
• 1.5 to 2 seconds should be long enough to produce a good etching
although this depends on the material to be etched
• clean the surface and the etching
• neutralize the surface with a cloth soaked in Neutralyt GN 2 several times
• then finally conserve the surface and the etching with Konservat GK 2
There is a special tool head for etchings wider than 30 mm.
