COMPLETE SPECIFICATION.
Process of Producing Intensely Brilliant Pictures, Ornamentations,
Inscriptions, or Drawings by Color-printing on Glass, and with a
Backing Stamped in Relief.
I, ADOLF GORLITZ, of 4. Muhlensteg, Zurich, Switzerland, 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 :-
The present invention relates to a process having for its object the production (in
a simple manner) on glass of intensely brilliant pictures, ornamentations, inscriptions
or drawings.
In order to carry out this process it is necessary to have a printing plate of
approximately the same size as the glass plate. The said printing plate is composed
of a material of suitable hardness and resiliency; rubber being very suitable for the
purpose.
The pictures, inscriptions, ornamentations or drawings are then engraved or
impressed in the rubber plate in a positive manner that is to say right way round
just as they are to be seen afterwards on the glass plate.
This printing plate is then coated with varnish-color which is then printed or
impressed by means of a press on to the glass plate.
When this has been done the glass plate is strewn according to the ornamentation
desired with bronze powder sheet metal or sheet aluminium or equivalent suitable
material. The places forming the drawings or inscriptions will theu remain empty
and will appear transparent whilst the remaining space is covered with the printing
color and is opaque.
A glass plate of this new kind-as compared with the plates heretofore produced
for the same purpose, usually by etching has the advantage of being able to be
produced with less labor and at less cost than the latter.
In the accompanying drawing:
Fig. 1 is an elevation, and
:-
Fig. 2 is a section on the line xx¹ through the glass plate.
A glass plate a treated in the manner herein before described is shown surrounded
with a frame g closed in at the back by a backing of strong paper board c.
On this paper board c there is fixed another but thinner paper-board mount or
backing upon which intensely bright or brilliant sheets of tin foil, tin-plate, or
patent foil b' bare pasted. The last mentioned paper-board backing is furnished
with prominent squares k which are stamped in at a suitable distance apart to suit
the inscription or drawing, &c.
When the backing is fixed to the glass plate at a suitable distance therefrom the
desired strong reflection of light is then thrown by the said squares through the
transparent portions of the glass plate.
It is obvious that the most varied effects can be produced by suitably selecting
the color and nature of the sheets of metal foil or backing.
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The process of producing intensely brilliant pictures, ornamentations, inscriptions
or drawings by color-printing and a packing stamped in relief, by first engraving
or impressing the desired picture drawings ornamentation or inscription in a positive
manner (right way round) in a plate or surface of suitable hardness, this printing
surface or plate being then employed to impress color upon a glass plate in such a
D

transparent so that with the help of a backing stamped in relief and coated with
metal foil or the like intensely brilliant reflected light effects are produced sub-
stantially as described and illustrated in the drawing.
