I WILLIAM GEORGE WHITE of The Polychromatic Simultaneous Printing
Company Limited 153 Queen Victoria Street in the City of London Engineer
do hereby declare the nature of my invention for " IMPROVEMENTS IN COLOR
PRINTING AND IN THE PREPARATION OF COLORS TO BE EMPLOYED THEREIN to
be as follows :-
"
This Invention relates to that system of color printing known as the Poly-
chromatic simultaneous system in which the printing block is built up of suitably
prepared materials containing the various colors which the design requires and in
which the printing block so built up of coloring materials imparts a portion of its
own substance to the fabric or surface to which it is applied. A former Patent
granted to me No 3047 in the year 1879 applies to this method of printing. I
dispense with the fatty compound as described in the previous Patent and in
lieu thereof I employ the paraffin or wax extracted from petroleum or other
minerals.
I reduce this substance to the consistency required with vegetable oils preferably
boiled linseed, poppy or maw oil.
Instead of using the ordinary pigment color I use colors made as follows:-
Blue,
60 parts water; sal ammoniac 12 parts; prussiate of tin pulp (cyanide of
tin) 60 parts; yellow prussiate of potash (ferrocyanide of potassium) 12 parts;
red prussiate of potash (ferrideyanide of potassium) 6 parts; tartaric acid
18 parts oxalic acid 1 parts; the mixture thus made I mix with alumina
say, one lb of alumina and one half pint of above mixture, the whole being
thoroughly incorporated laid on suitable vessels and dried-After drying they
are finally ground and mixed with the compound above described in the
following proportions say 1 lb of color to 1½ lbs of compound as above and

page_text: I cllow,
Persian berry liquor 36 parts; alum 2 parts protoxide of tin 4 parts;
these are then mixed with one pint of liquor to one pound of pipe clay, dried
and finally ground-one lb of color to 11 lbs of composition.
Red,
Japan wood liquor 18 parts; bark liquor 4 parts; nitrate of alumina
4 parts; water 9 parts, oxalic acid one part; alum of a part; chlorate
of potash part; this is then mixed with one pint of above color to one
pound of pipeclay dried ground and mixed with compound say one lb of color
to 2 lbs of mass.
Black,
Logwood liquor 58 parts; bark liquor 13 parts; acetic acid 11 parts,
water 4 parts; chlorate of potash 1 part-nitro acetate of chrome 9 parts;
one lb of pipeclay is thoroughly dissolved in pyrolignite of iron added to this
is one pint of the above black liquor.
The cloths to be printed after being properly mordanted are slightly damped
with turps before printing. After printing the goods are passed through a weak
benzine bath to extract fatty matter the goods are then aged and steamed in the
ordinary way washed and soaped to remove the pipe clay or earthy matter thus
eaving only the dye on the cloth.

I WILLIAM GEORGE WHITE of The Polychromatic Simultaneous Printing
Company Limited 153 Queen Victoria Street in the City of London Engineer
do hereby declare the nature of my invention for "IMPROVEMENTS IN COLOR
PRINTING AND IN THE PREPARATION OF COLORS TO BE EMPLOYED THEREIN
and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
"
This invention relates to that system of color printing known as the Poly-
chromatic simultaneous system in which the printing block is built up of suitably
prepared materials containing the various colors which the design requires and in
which the printing block so built up of coloring materials imparts a portion of its
own substance to the fabric or surface to which it is applied. A former Patent
granted to me No 3047 in the year 1879 applies to this method of printing.
I dispense with the fatty compound as described in the previous Patent and in

page_text: Acetic acid
Acetate of alumina
Nitrate of alumina
Sulphocyanide of alumina
Acetate of lime
11 parts
3 parts
2 parts
21 parts
5 parts
One gallon of the above compound is well mixed with six pounds of China clay
and the mixture is placed in a tin tray and stoved. After being well dried one
and a half parts of it is ground with one part of paraffin compound.
The block is prepared from the variously colored paraffin compounds by suitably
shaping the pieces and fitting them together according to the design.
This design appears on the surface of the block and each time the block is
applied to a fabric a portion of the color is transferred from the block to the fabric
until at last little or nothing remains of the block.
The cloths to be printed after being properly mordanted are slightly damped
with turps before printing. After printing the goods are passed through a weak
benzine bath to extract fatty matter the goods are then aged and steamed in the
ordinary way washed and soaped to remove the pipeclay or earthy matter thus
leaving only the dye on the cloth.
What I claim is
3 (1.) The use in color printing substantially as described of printing blocks built
up in various colors from compositions in which the coloring matters or pigments
are combined with paraffin or wax extracted from petroleum or other mineral.
(2.) The combination substantially as described of coloring matters or pigments
with paraffin or wax extracted from petroleum or other mineral.
(3.) A polychromatic printing block built up in various colors from compositions
consisting of coloring matters. or pigments combined with paraffin or with wax
extracted from petroleum or other mineral.
