COMPLETE SPECIFICATION.
A New Method of Treating Metallic Foil in Order to Prepare it for
Printing Purposes.
I, ERNEST HOSKING, of No. 489 Flinders Lane, in the City of Melbourne, in
the Colony of Victoria, Printer, 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 of a new method of treating metallic foil in order to prepare it
for printing purposes, consists in mounting metallic foil on any suitable backing
so as to prepare it for printing upon. This backing may consist of any pliable
material which is thin enough for the purpose but I prefer to use paper, card-
board or any other material partaking of the character of paper, although thin
textile materials, such as fine cloth, silk or linen may be used to produce certain
effects, as hereinafter described.
The metallic foil is made to adhere to its backing by interposing some adhesive
material, such as paste, between them, and afterwards subjecting the foil and its
backing to a heavy pressure in a screw or other press for a period of from
twelve to twenty four hours, after which it must be allowed to dry before it is
printed upon.
The preparation of this material in this way constitutes my present invention.
Its principal uses are to enable permanent impressions to be printed thereon by
an ordinary printing machine, so as to produce elegant effects on a durable material
at a comparatively low cost, thus the letters or designs may be so printed as to
present a flat surface, or they may be raised or embossed.
It is of course well known that metallic foil is now made in a variety of patterns,
which can be so selected as to assist in producing the desired effect, and inks, paints
or lacquers of any tinge or colour can be used for the purpose of heightening such
effect, and in addition to this, the effect may be varied by the use of textile
material such as the backing. This will give the appearance of printing on the
material thus used.
In actual practice I first make a male and female die which I then fit into an
ordinary printing press and place the prepared material on the male die, and then
set the machine in operation, with the result that a beautiful embossed design is
produced, which is both elegant and durable.
In some cases, bronze and other powders may be used for producing other effects,
and if so preferred, the male die may be dispensed with and the female die alone
used, in which case the letters or design will appear on a plain surface and not
raised.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
My new method of treating metallic foil in order to prepare it for printing
purposes, which method consists essentially in mounting metallic foil on any pliable
material which is thin enough for the purpose, such as paper, card-board or textile
material, then pressing the two layers of material together, and finally drying it,
substantially as herein described and explained.
Dated this First day of May. One thousand eight hundred and ninety-three.
