PROVISIONAL SPECIFICATION.
An Improved Process for Imitating Damask and the like Fabrics,
principally intended for Wall Coverings.
I, KARL GEBHARDT, of 32, Gabelsbergerstrasse, Munich, in the Empire of
Germany, Professor, do hereby declare the nature of this invention to be as
follows: :-
This invention relates to imitation-damask and similar fabrics, which on
account of their cheapness are especially suitable for wall-coverings for replacing
for instance silk-damask or the like.
For which purpose jute or any other suitable cheap fabric or cloth may be
taken. The same is then dyed or coloured a bright ground-shade over the whole,
or the ground-color is produced by means of a superficial painting with any colour
(for instance wall paper colour). Then the design is made on it by means of a pattern
in a strong bright colour. After being dried, this same pattern is again used and
laid over the pattern previously produced, and is displaced as much upwards and
sidewards, where light-edges are necessary, as one wants to obtain more or less
strong light-edges. When the pattern is laid on in such a manner, the design is
made with dark colour and shaded in a picturesque manner, so that the first
(bright) colour remains as lustrous colour and the second (dark) colour gives the
shadowing in different shades. By the displacement of the pattern the parts
necessary as light-edges cannot be met by the dark colour and in the simplest
manner an imitation of fabric is obtained which resembles silk-damask.

An Improved Process for Imitating Damask and the like Fabrics,
principally intended for Wall Coverings.
I, KARL GEBHARDT, Professor, of 32, Gabelsbergerstrasse, Munich, in the Empire
of Germany, 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 relates to imitation damask, and similar fabrics, which on account
of their cheapness are especially suitable for wall coverings for replacing for
instance silk damask or the like.
For this purpose jute, linen, cotton, or any other suitable cheap fabric or

page_text: cloth may be taken. Also paper, coloured fabric with brilliant surface (satin,
sateen, or the like).
When one uses jute or the like undyed fabric, it is dyed in a bright ground shade
over the whole, or the ground colour is produced by means of a superficial painting
with any colour (for instance wall paper colour). Then the design is made on it
by means of a pattern in a strong bright colour. After being dried, the same
pattern is again used and laid over the pattern previously produced, and is dis-
placed somewhat upwards or sidewards, where light edges are necessary more or
less, as one wants to obtain more or less strong light edges. When the pattern is
laid on in such a manner, the design is made with dark colour and shaded in a
picturesque manner, so that the first (bright) colour remains as a lustrous colour
and the second (dark) colour gives the shadowing in different shades.
In the annexed drawing:
Fig. 1 shows the first part of the process, where the design in made with the
pattern in bright colour."
In Fig. 2 the pattern is displaced for the distance a and it can be seen there-
from, how the light edges are formed.
When the before described process is to be carried out by machinery (hand
printing presses, or wall paper printing machines) the printing forms or printing
rollers are arranged in a displaceable manner, so that they can be displaced after
the first printing for the width of the light edge to be obtained (like the pattern).
When one uses paper or coloured fabric with brilliant surface for producing
imitation silk, or damask, one proceeds in the following manner:-
66
the
When using paper the ground colour is first put on where required, thus
'shadowing down the ground work of the design. Then the design is printed
on with bright colour and then after having displaced the pattern, the printing
forms or printing rollers the design is printed again with a dark shade, whereby
the places forming the light edges are not covered by the dark colour. The pro-
cess is the same when using fabric with brilliant surface. In the same the brilliancy,
forms the lustre, which is obtained in the usual fabric by "shadowing down
ground, a further “shadowing down" of the body of the design can then be made.
The characteristic feature of this new process is the displacement of the pattern
or the printing form or roller. By displacing the patterns or the printing rollers
or printing forms, the places required as light edges cannot be covered by the
dark colour and one obtains in the most simple manner an imitation fabric, which
has completely the appearance of silk damask.
The cost of the manufacture is so small, that the product can be used in various
ways as replacement for silk fabrics for wall coverings, or any other decorative
purposes.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
An improved process for imitating damask and similar fabrics for wall cover-
ings, whereby the design is printed with a bright colour on any fabric or cloth
(jute, satin, sateen, or the like) or also on paper on which a suitable "ground"
has been printed, and then after a suitable small displacement of the pattern or
of the printing form or printing roller the same design is printed again with a
darker colour whereby the light edges necessary for a good effect remain free.
