Colours or Tones by One Impression.
We, FRANCIS CORNWALL TAYLOR of 2095 Mexican Avenue New York, in the
County and State of New York, United States of America, Printer, and JOSEPH
COOKE of Fargate, Sheffield, in the County of York, Newspaper Proprietor, do
hereby declare the nature of this invention to be as follows:-
Hitherto when a sheet of letterpress has been required to be printed in different
colours it has had to pass through several pressing operations varying according to
the number of colours to be printed. It has been attempted, though it has never
been carried into practical effect, to distribute various coloured inks in lines or
rows over the inking plate and thus allow the type iuking rollers to take up tho
ink in circular bands and to distribute it on the various lines of type. The attempt
however, has not proved successful, owing to the tendency of the colours to run
into each other, thus effectually preventing olean or accurate printing in various
colours.
The object of our invention is to treat the ordinary inks of commerce used in
printing in such a manner that the inks applied to the inking plate are confined to
the positions in which they are applied, thus enabling us to employ different and
various inks for the purpose of printing in various colours from one form of type ;
all at one operation.
According to our invention, we take an ink of the desired colour and add to it
a portion of the following compound oz. balsam of copaiba, oz. glycerine,
dram to 2 drams sandle-wood oil, dram petroleum, dram balsam fir, dram
turpentine, and dram tincture of myrrh. On the above compound being added
to the ink, add a mixture of oz. ether and oz. chloroform. When the above
have been mixed add 1 oz. of pure ammonia, otherwise known as 880 ammonia.
The above mixtures may either be made up by the printer or made in larger
quantities previous to use, and the ink when treated as above described becomes of
such a strong character that it is not liable to open or spread sideways from the
position in which it is first placed on the ink table. This property of the inks
enables various colours to be placed in close proximity to each other in bands
round the ink roller, from which they are transferred to the ink table, and the
pressure of the type inking roller, although it equalises the inks on their various
fines, does not blend or mix them to any extent.

Colours or Tones by One Impression.
We, FRANCIS CORNWALL TAYLOR, of 2095 Mexican Avenue, New York, in
the County and State of New York, United States of America, Printer, and
JOSEPH COOKE, of Fargate, Sheffield, in the County of York, Newspaper
Proprietor, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement :-
Hitherto, when a sheet of letterpress has been required to be printed in different
colours, it has been passed through the press several times, varying according to
the number of colours to be printed. Attempts have been made to distribute
various coloured inks in lines or rows over the inking plate, and thus allow the
type inking rollers to take up the ink in circular bands and to distribute it on the
various lines of type. These attempts however have not proved successful, owing
to the tendency of the colours to run into each other, thus effectually preventing
clean or accurate printing in various colours.
The object of our invention, is to treat the ordinary inks of commerce used in
printing, in such a manner that inks applied to the inking plate are confined to the
positions in which they are applied, thus enabling us to employ different and various
inks for the purpose of printing in various colours from one form of type; all at
one operation.
According to our invention, we take the various coloured inks which are to be
used in the printing process and treat each in the manner hereafter described.
First add to the ink a suitable portion of a compound composed of the following
ingredients:oz. balsam of copaiba, oz. glycerine, dram to 2 drams sandle-
wood oil, dram petroleum, dram balsam fir, dram turpentine, and dram
tincture of myrrh. On the above compound being added to the ink, add a mixture
composed oz. ether and oz. chloroform. When the above have been mixed,
add 1 oz. of pure ammonia, otherwise known as 880 ammonia.
The ink treated as above described, becomes of such a strong character that it
is not liable to open or spread sideways from the position in which it is first placed
on the ink table, and owing to the bubbles which are formed in the ink on the
addition of the compounds above described, the said ink easily distributes itself.
The compounds for mixing with the ink may be either made up by the printer or
they may be made up in larger quantities previous to use, and when the inks are
prepared printing in various colours at one impression may be carried into effect in
the following manner :-The various coloured inks are fed to an inking roller in
such a manner that the ink is taken up on the roller in a series of bands or rings.
These bands or rings may be in close proximity to each other, and as the table
reciprocates the colours are transferred to the said table from the roller in the
form of parallel lines. The positions of the lines of colour correspond to the lines
of type which are required to be inked, and the type iuking roll or rollers take up
the ink from the table and transfer the various colours to the various rows of type.
The strong character of the inks enable them to be worked in close proximity to
each other without allowing them to mix or blend at their edges to any extent, and
the working of the rollers on the iuk table spread the inks equally in a longitudinal
direction by reason of the breaking of the bubbles.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. The employment of the ingredients hereinbefore described, whereby the

page_text: ordinary inks of commerce used in printing may be treated so as to confine them
on the inking table and rollers to the positions in which they are applied, substan-
tially as and for the purposes set forth.
2. The employment of the compounds, composed of balsam of copaiba, glycerine,
sandle-wood oil, petroleum, balsam fir, turpentine, tincture of myrrb, ether, chloro-
form, and ammonia, substantially as and for the purposes set forth.
3. The employment of balsam fir and tincture of myrrh in the preparation of
printers inks for printing in various colours, substantially as set forth.
