Improved Process and Means for Printing Paper-hangings, Fabrics,
Leather, and other goods.
We JOSEPH THOMAS PETITJEAN of 26 Rue Saint Bernard, and CHARLES
FREDERIC MAILLARD of 19 Rue Durantin, both of Paris in the Republic of
France, Manufacturer and Designer respectively 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:-—
Our invention consists essentially of a new process of manufacture allowing
patterns comprising any number of colours to be printed on paper, fabrics, leather
or any other suitable material, and that by a single impression of the plate without
being obliged to renew the colour or the coloured substance after each application
of the plate.
This process thus offers several very important advantages, it avoids several
successive applications of the plate for a single pattern, which in processes at
present employed require as many plates as there are different colours; it does
away with the necessity of multiple registers, and the defects arising from faults
in the fitting, finally, it allows of the most varied designs being executed whatever
may be the number of shades or colours employed, with as much economy as
printing in a single colour.
This improved process will now be described, reference being made to the
accompanying sheet of illustrative drawings which shows a form of apparatus
allowing it to be practically carried out. We employ a plate or engraving block P,
Figure 1, the dimensions of which vary according to requirements (for instance, if
paper-hangings are to be printed it may have the dimensions of an entire piece and
be taken asunder in pieces). This plate no longer presents in relief or in intaglio
the strokes of the drawing as in the processes at present employed for printing but
merely the contour of these strokes formed in metal, wood or any other suitable
material. We give to these partitions sufficient height to form a kind of separate
tubes which contain the colouring or coloured matter which is to be used.
All these partitions are held laterally by frames if necessary and they are fixed on
a bottom plete which itself rests at the bottom of a box D suspended by means of
two trunnions A and B in suitable supports.
It is preferable to interpose between the bottom of the block P and the bottom
of the case D a kind of elastic cushion, formed of india rubber, metallic springs or
the like. The upper edges of the partitions are carefully planed so as to form a
thoroughly level surface, and in order that the openings of the tubes may be
hermetically closed by the sheet of paper or fabric which is to be printed.
The apparatus being in the position shown in Figure 1, each tube or cylinder is
filled with the colour or coloured substance which it is desired to employ.
Supposing, for instance, velvet or flock paper is to be printed, flock or wool powder
of various shades must be inserted in the cylinders, each of them containing a
certain coloured powder absolutely separated from the adjacent powders. When
this has been done, that is to say, when the plate is ready, it is covered with the
paper which is to receive the application of the velvet powder, and on which the
pattern has been imprinted in gum or other mordant by the usual processes.
The lid C which is suspended by chains to pulleys, or rollers, is then lowered,
and is firmly fixed by means of the bolts K after the chains supporting it have
been detached. This lid is preferably coated inside with an elastic covering forming
a cushion.
The matters being thus in place, the box D is reversed by being
trunnions A and B to bring it into the position shown in Figure 2.

The bottom of the box D may be struck with canes in order to shake up the powder
or flock in the tubes or cylinders containing it and cause it thus to be more uniformly
deposited.
When this has been done, the box is returned to the position of Figure 1, the
lid C is lifted off, and the sheet of printed paper is removed and replaced by a fresh
one. The operation is repeated as long as there remaius any colouring matter in
the tubes of the plate.
We obtain, therefore, by this process an improved and very economical manu-
facture of products, since they are the result of a single operation, whatever may be
the number of colours and which are very rich because as many different shades may
be obtained as there are partitions.
It is unnecessary to state that this process may be applied to papers with a white
foundation as well as to those with a coloured, silvered, gilt, bronzed, etcetera, founda-
tion; and that the flock mentioned in the above example may be replaced by
metallic or other powders and even by colours thickened to a suitable extent or
incorporated with inert powders serving to some extent as absorbers.
In the same way this process may be applied to printing in colours on fabrics,
leathers or other foundations.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is
1. An improved process for printing paper hangings, fabrics, leather, and other
goods, consisting in preparing a plate, the engraving on which corresponds to the
contours of the patterns, and is composed of partitions of a certain height forming
separate tubes which are filled with coloured inatter. The plate being then covered
with the sheet which is to be printed, and the whole turned upside down, in such
a way that the different colours, or coloured substances are simultaneously fixed
on the patterns without becoming mixed or encroaching one on the other, sub-
stantially as described.
2. For carrying out the process described in Claim 1, the construction and use
of a box D mounted on two trunnions (A and B) with a detachable lid (C) having
an internal cushion and held firmly by means of bolts (K), in combination with the
plate having partitions (P), lying at the bottom of the box on an elastic cushion,
substantially as described with reference to the Figures 1 and 2 of the accompanying
drawing.
