HENRY BOCK BINKO, of the Firm of Binko & Co., 12, Coleman Street, Bunhill
Row, Loudon, E.C. "AN IMPROVED PROCESS TO PRODUCE AN UNLIMITED
NUMBER OF COPIES ON ANY MATERIAL IN BLACK OR ANY OTHER COLOR WITHOUT
MECHANICAL PRESSURE."
Until now only two kinds of multiplying apparatuses without press have been
successfully used, one of which by means of stencil paper, which has, however, the
difficulty of producing the stencil properly, and the other, like my well known
printograph and other similar apparatuses, where the reproduction is principally
done by means of soluble or aniline inks. In this latter caso only from 50 to 100
copies can be obtained, and only in fancy colors and not in black on account of
their being no black soluble color of sufficient intensity in existence, and as the
demand for commercial, official, and general use is specially for black ink, an
improvement was necessary combining the simplicity of the printograph kind with
the possibility of getting copies in black as well as in other colors, and in any
number required. My Invention has the property of doing this effectually and
simply, and consists of a pad, or of the composition of the pad, fixed to any kind
of material or receptacle, and a special copying ink, which with other necessary
articles like printing inks, sponge, and rollers, etc., etc., altogether put up in a
box forms the complete apparatus. The formula giving the chemical proportions
of the composition of the pad and ink will be fully detailed in the final
Specification, the first consisting principally of printers' roller composition, and
the second of an aluminous solution.
I will now describe the process showing the novelty of application.
The writing or drawing is done with the special prepared copying ink of an
aluminous solution on paper, and left to dry without blotting. In the meantimo
wash the pad with a sponge and cold water several times, a few drops of glycerine
added to this water is advisable, but not necessary.
The original when dry is placed face downwards on the pad, and rubbed down
evenly for about three minutes, then tako the original off, and you will find a
perfect negative on the pad. Now take some printing ink, black or any other
color, put same for convenience sake inside the box lid, and by rolling a printer's
roller over it like printers do, you will get the ink evenly all over the roller.

page_text: After which take the roller and roll the same over the pad till every part of the
negative is well inked, never mind if the other parts of the pad get likewise some
ink. It is necessary to get off the superfluous ink; to do so first place a sheet of
paper on the pad, rub it gently and take off; the rest of the superfluous ink must
be washed off carefully with sponge and water, of course taking care to leave the
negative like litho printers do to keep the stone clean. Now use again the printer's
roller as before, and if the pad has already sufficient dampness, the negative only
will take the ink, if not wash off again the superfluous ink till you get a clear
inked negative.
To get the required number of copies simply place the paper on the negative,
-rub.it over slightly and take off, and you will have a copy in every way similar as
done by lithographic process. Any number-of-copies_can_bo_taken by repeating
the last, and simply inking the negative with the roller whenever the "copics
appear pale. To remove the negative wash off with sponge and hot water.
My Invention, as described here, gives all the advantage of a lithographic print,
but dispenses with any kind of mechanical pressure; it works quickly, and in fact
makes every body independent of a printer.
