the like.
We CHARLES EBENEZER CHALLIS of No. 30 Navarino Road, Hackney
London N.E. Machinist, and JAMES CHALLIS of No. 22 Cricketfield Road
Hackney Downs, London N.E. Commercial Traveller do hereby declare the
nature of this invention to be as follows :-
By our invention it is intended to produce show bills posters &c. for advertising
and other purposes by printing direct from the stone or blocks upon a prepared
surface on textile or other materials; thus avoiding the objectionable method of
printing on paper and afterwards mounting upon linen; or the expensive and
troublesome method of printing upon paper and then transferring on to suitably
coated metal, canvas or other material by means of transfer varnish, pressing to
secure the adhesion of the design and then soaking off the paper.
Our process consists in coating textile fabrics, wire gauze or other suitable
material (either waterproof or otherwise) with a compound such as a mixture of a
drying oil with white lead; or gelatine with metallic oxide or other pigment; or
starch, gum or mucilage with chalk or china clay, these being treated or combined
with other materials when desired in order to render the compound tough, elastic
or waterproof; or we may partly dissolve the substance of the material and
subsequently neutralize the solvent. The surface is smoothed and prepared for
printing by flatting and rolling.
The material is laid in the press backed with a sheet of rubber or blanket in
order to allow for the hardness of the web (when necessary) and the impression is
printed by a similar method to that employed in printing upon paper; after
drying the bills &c. are varnished and mounted or framed as required.

COMPLETE SPECIFICATION.
Improved Process for Producing Show Bills, Posters, Pictures, and
the like.
We, CHARLES EBENEZER CHALLIS of No. 30 Navarino Road, Hackney
London N.E. Machinist, and JAMES CHALLIS of No. 22 Cricketfield Road,
Hackney Downs, London N.E. Commercial Traveller, 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 :-
By our invention we produce show bills, posters, etc. for advertising and other
purposes by printing direct from the stone or blocks upon a surface prepared on
textile materials.
Our process consists in "filling" a textile fabric with a waterproofing compound,
such as a drying oil mixed with white and red lead and vegetable or lamp black or
other pigment, and drying, flatting or rolling; then surfacing with a somewhat
absorbent compound that will take up the printed colour, such as boiled oil,
turpentine, white lead or zinc white and any pigment for producing a desired tint,
and again drying and flatting or rolling, after which the sheet is ready for printing.
Or the fabric is coated with a waterproofing compound as described above and
then surfaced for printing with a mixture of size, gelatine, starch or gum with a
LD
ונג

page_text: mineral white such as china clay or metallic oxide and finished by drying, rolling
and polishing with french chalk.
Or the fabric (indurated or otherwise) is "filled" with a mixture of gelatine and
metallic oxide and (or) other pigments-rolled and then surfaced for printing as
last described. In this case we rely for waterproofing upon painting the back and
varnishing the face of poster after printing.
The prepared material is laid in the printing machine backed (when necessitated
by the hardness of the web) with a sheet of rubber or other "blanket" and the
impression is printed in the same manner as upon paper-except that it is sometimes
advisable to use more dryers in the ink, and the sheets when taken off the machine
require interleaving with a coarse porous paper, or racking to allow for drying.
The printed sheet is varnished and mounted or framed in any desired manner.
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 preparation of material for printing upon substantially as herein
described and set forth.
2. Show bills, posters, pictures and the like, produced by printing direct upon
suitably prepared textile material, substantially as described and set forth.
