PROVISIONAL SPECIFICATION.
Improvements in Printing Designs upon Calico, Paper, and other
Materials.
I. ISIDOR FRANKENBURG, of Greengate Rubber and Leather Works, Salford in the
County of Lancaster, India-rubber Manufacturer, do hereby declare the nature of
the said invention to be as follows:-
This invention relates to the ornamenting of the surfaces of fabrics paper leather or
other materials.
I find that an unproofed or raw surface of the material may be printed upon with
colours prepared with a rubber thickening which produce effects differing from and.
for many purposes superior to those produced by dyes in ordinary calico or paper
printing.
The invention therefore consists in ornamenting an unproofed or unprepared
surface of grey calico or other fabric paper leather or other material with pigments
aluminium or other bronzes prepared with a rubber thickening.
In carrying out the invention I take a suitable pigment or metallic bronze,
preferably aluminium bronze and prepare therefrom a composition mixed with or
suspended in rubber solution or other mixture of rubber to give the thickness or
consistency.
With this mixture or composition I print upon an unproofed surface of the material
any desired pattern or design.
When so printed if desired the surface may be covered with a coating of rubber
proofing, shellac lacquer or other varnish.
After printing the rubber may be vulcanised or finished in any suitable way.
Dated this 11th day of April 1896.

COMPLETE SPECIFICATION.
Improvements in Printing Designs upon Calico, Paper, and other
Materials.
I, ISIDOR FRANKENBURG, of Greengate Rubber and Leather Works, Salford, in the
County of Lancaster, India-rubber Manufacturer, 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 :-
This invention relates to the ornamentation of textile fabrics, paper, leather, and
other materials possessing surfaces suitable for printing on.
I find that an unproofed surface of any material may be printed upon with colours
prepared with an indiarubber thickening, and the effects so produced are different from
and in many respects superior to those produced by printing upon these surfaces with

page_text: aniline dyes, pigments, or lake pigments prepared with the ordinary thickenings, or
thickening, or fixing agents commonly employed in printing.
This invention therefore consists in printing upon an unproofed, or otherwise
prepared, surface of grey, or dyed, or ordinarily printed, calico or other fabric, paper,
leather, or other material, with pigments, lake pigments, aluminium powder, or
metallic bronzes, or powders capable of coloristic effects prepared with a thickening
of indiarubber.
In carrying out this invention I take a suitable pigment, lake pigment, metallic
powder or bronze, and mix it in variable proportions, depending upon the desired
intensity of the printing effect, with indiarubber solution. This mixture is then
rendered perfectly homogeneous by passing it as often as may be required through
conoidal or roller mills.
With the mixture prepared as above described any desired design may now be
printed upon the surface of any of the above named materials, either with the
ordinary printing machine, or with blocks or stencils. The materials thus printed
upon require no further treatment beyond a passage over hot drying cliests or
drums. But if the colours printed in this manner consist of metallic powder dust
or bronze a passage of the materials printed therewith through a polishing machine or
calendar greatly enhances the beauty of the printed effects.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The printing on either the grey, or natural, dyed, or printed surfaces of textile
fabrics, paper, leather, and other materials with pigments, lake pigments, aluminium
powder or other metallic powders or bronzes prepared with an indiarubber thickening
substantially as described.
