Sometimes it is necessary to wipe out a design from a background. In
this case the following suggestions are recommended:
The design to the “cut out” must be seen from underneath the tint. A
design to be wiped out of a tinted background must necessarily be drawn
in with India ink. For dusted grounds the oil should be wiped off the
ink lines with a pointed stick so that the tint will not adhere to the
line.
Dusted backgrounds require about twenty-four hours to dry, but by
artificial heat the time is considerably shortened. To remove the tint
covering the design, make a mixture of oil of cloves and a few chips of
soap. Apply a light coat and be careful that it does not spread beyond
the lines. The color requires about five minutes to soften and may then
be removed with a piece of cloth over the finger tip. Do not try to
remove the tint until the design is perfectly dry. Use care in removing
the color so as not to drag it over onto the background, change cloth
frequently so that you are constantly working with cloth free from oil
and color.
Designs may be “cut out” from powdered background by using a stick and
scraping off the tint. It should be done while the tint is still fresh.
The former method, however, is more satisfactory, tar oil may be used
instead of oil of cloves if preferred.
