A New Kind of Artistic Decoration for Walls and other Surfaces.
I, EMILE VICTOR CAMIS, of 172, Quai Jemappes, Paris, France, 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 has for its object a novel kind of artistic decoration in imitation
of oil painting on canvas, water colours or pastel drawing &c.
My invention consists essentially in the application of photography, typography,
and all kinds of colour printing upon paper or prints from stone, or plates of any
dimensions, for the decoration of walls, ceilings, panels, screens &c., and the inven-
tion is characterized by the application of an entirely novel process having for
object to incorporate all kinds of paper, tissues, powders &c., in the meshes of
canvas in such manner that the canvas will be reinforced, and the paper, tissue
or powder &c., and canvas form one and the same structure.
By means of my process I am enabled to render possible the reproduction of
any picture and to produce real masterpieces of decoration in imitation of pastel
or water-colour drawings or oil paintings. This novel process differs entirely
from those in which imitations of coarse grained or other fabrics are produced
by milling or pressing.
In carrying out my process in practice, I employ pure rag paper slightly sized
but sufficient to prevent spreading under impression and preserve its spongy
qualities so that when once it has been impregnated with the adhesive product,
it may under the pressure of the machine cylinder become incorporated with the
canvas and form a single body presenting the exact appearance of a real oil paint-
ing. The paper here forms a substitute for the first ground coat, which painters
always apply to their canvas. The canvas employed may be of any kind provided
it be of good quality, but especially one having a prominent structure to facilitate
under pressure a special very light coating with paste. The adhesive product is
comprised of rye flour mixed with dextrine to which is added a small proportion
of cold glue and gum-arabic.
My process consists essentially in coating the canvas with an even layer of the
above product and then impregnating the paper with the same product, care being

page_text: taken to apply another coat of a stronger paste around the borders. The paper is
then applied upon the canvas and passed between pressing rollers, the pressure
being so regulated as to cause the paper, while in a pasty condition to become
incorporated with the canvas and form a single body therewith, the colour being
at same time absorbed by the fabric of the canvas.

operation terminated at a certain degree of dryness, I now mount each print upon
a separate panel and fix by nails placed at about every two inches apart in order
that they may be perfectly strained under the best possible conditions. When the
painting is thoroughly dry it should be covered with say two coats of permanent
varnish.
Hitherto lithographic prints on paper have never been applied to wall decora-
tion as it always resembled a coloured print, whereas by my process, owing to the
paper being incorporated with the canvas, the aspect of the lithograph becomes
entirely altered and there is nothing to show either to the sight or touch that the
picture has been pasted on. Moreover all attempts hitherto made of utilizing litho-
graphy for decorative purposes have failed owing either to the difficulty of
printing on large sheets of paper, canvas or canvas paper and also to the difficulties
of matching. These difficulties I have sought to overcome in order to obtain a
perfect imitation of paintings and pastel work by specializing the reproductions,
compositions, matchings inalterability and consequently the strength. My process
thus permits of producing artistic decorative effects, by the perfect imitation of
paintings and pastels of all dimensions and especially of large sizes hitherto
unknown in lithography.
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:
1. The new product obtained by the incorporation in the fabric of a canvas of
reproductions obtained by photographic or typographic printing in colour on
paper, tissues, powders &c., this new product imitating painting, pastel work, water
colour etc., and enabling the production in all sizes of artistic decoration on walls,
panels, screens &c.
2. A special process of mounting or lining whereby to obtain the new kind of
artistic decoration above claimed, as herein described and for the purpose specified.
