When you have obtained these requisites go to
any hardware store and get a rubber mat about
a quarter to a half inch thick what is called
a 'kneeling mat' will do very well. These are
necessary to make a springy cushion so that the
fine lines come out clearly. Place a sheet of
the coated white paper on the upper surface of
the rubber mat. Smooth out a small portion of
the printers ink by running the gelatine roller
over it on a piece of glass. When all is ready
run the gelatine roller over the subject's left
and right hands press them firmly down on the
sheet of paper, turn the hand over on the back
and with the flat part of the thumb press the
paper lightly into the hollow of the palm and
wrist, peel off the sheet of paper, starting from
the fingers and you will find you have obtained
a clear impression of all the lines of the hand.
You may at first find some difficulty with persons
who have a dry, acid skin, which may make the
imprints in many cases look spotted. This can
be got over by first washing the hands you are
going to treat with warm water, drying them
thoroughly and sprinkling with a light dusting
of some powder like talc. If you have not got
talc a little chalk will do as well. There are
many ways of removing the printer's ink from
the hands.
The
simplest and best is to get a small tin of the
powder sold at all motor supply stores for cleaning
oil and grease off hands, rub this on the hands
in hot water and the ink will come off easily.
