Improved Processes for Contact Printing and Obtaining Reliefs in
Photography, and Means or Apparatus to be Employed in such
Processes.
I, ALFRED HART, of 16 Upper Bedford Street, Brighton, in the County of Sussex,
Photographer, do hereby declare the nature of this invention to be as follows:-
In carrying out this said invention I proceed as follows-I make a Dry plate for
Contact-printing with a Bromide, or other suitable Emulsion, which I coat in the
ordinary manner, the mediums I employ in the place of Glass or Paper, are-
Celluloid, Vulcanite, India Rubber, and a material manufactured under the name of
"Everclean," and the like.
The advantages of these compositions and materials are, their durability and non-
liability to breakage, and the control I hold over them in giving them any desired
tint, which I can do in any shade or colour, and by giving them a finishing coat of
the same materials in a liquid and transparent state, render them thoroughly
impervious to air and water.
This forms part of my invention, or I can by the aid of the above mentioned
compositions and materials produce a photograph in relief in the following
manner;-
I make a series of perforated plates each perforation representing different different
parts of the picture where relief is desired. In doing this I employ an Iron Box
one inch in height, more or less as required, on the inside bottom of which is an
India rubber cushion half an inch in thickness and the exact size of the picture to
be embossed, the print being laid face uppermost on the India rubber cushion, the
plates being laid over it alternately an Iron plate one inch in thickness is placed over
the perforated plate, a part of which protrudes from the top of the Iron box, this
being placed in an Hydraulic or other press the India Rubber is forced into the per-
forated parts of the plate, thus giving the desired relief. I continue to change the
plates untill all the parts requiring relief are obtained. To enable me to carry out
this part of the process I use Celluloid, Vulcanite, India rubber, and a material
manufactured under the name of "Everclean," and the like, as the means of with-
standing the pressure necessary to produce such relief.

page_text: The indent at the back of the picture produced by the pressure is filled with a
suitable cement, which protects them from all injury that might be caused by undue
pressure.
Having now described the nature of my said invention and in what manner
the same is to be performed I declare that what I claim is :-
The process of producing an Embossed photograph by the aid of perforated plates
and the use of the aforesaid flexible compositions for the production of the same and
furthermore for making Dry plates for Contact printing from the same.
In witness whereof, I the said Alfred Hart have hereunto set my hand and seal
this Fourth day of April, in the year Eighteen hundred and eighty-eight.
