Typewriter Ribbon Inks
1. Take Vaseline
(petrolatum) of high boiling point, melt it on a water bath or slow fire,
and incorporate by
constant stirring as much lamp or powdered drop black as
it will take up without becoming granular. If the Vaseline
remains in
excess, the print is liable to have a greasy outline; if the color is in
excess, the print will not be clear.
Remove the mixture from the fire, and
while it is cooling mix equal parts of petroleum, benzene, and rectified
oil
of turpentine, in which dissolve the fatty ink, introduced in small
portions, by constant agitation. The volatile
solvents should be in such
quantity that the fluid ink is of the consistence of fresh oil paint. One
secret of
success lies in the proper application of the ink to the ribbon.
Wind the ribbon on a piece of cardboard,
spread on a table several layers of
newspaper, then unwind the ribbon in such lengths as may be most
convenient,
and lay it flat on the paper. Apply the ink, after agitation, by means of a
soft brush, and rub it
well into the interstices of the ribbon with a
toothbrush. Hardly any ink should remain visible on the surface.
For colored
inks use Prussian blue, red lead. Etc., and especially the aniline colors.
