The present invention has for its object a new mode of printing chromo-lithographs
devised to supersede the long and delicate operations heretofore required to impress
the required layers of colour.
Heretofore after the stones, each one of which contains the impression of one of the
colours which is to form part of the chromo-lithograph, have been inked with their
special colour, the sheets of paper to be impressed are applied to the different stones,
one after the other in succession, care being taken to make the sheets correspond
exactly at each impression by means of a mark in the form of a cross. It results from
this, that if one impression is adjusted badly, the different colours will over lap one
another and produce a disagreeable effect in the picture.
My new method of printing has for its principal object the obviation of successive
impressions, and the inconveniences attending them. It is based upon the following
process, which I will describe as applied to the printing of a design in two colours for
the purpose
of clearly setting forth its details.
Upon a metal plate of any kind or on a block, I draw say a monogram or a bouquet
or any other design and afterwards cut out or remove that part of the figure which is
to be of a different colour in the picture from the remaining portion. The portion
removed is fixed in a suitable manner on a second plate of metal or other material.
I therefore have now two blocks each bearing the part of the design which is to
he impressed with a different and special colour, each of these plates is inked separately
with its colour as in existing processes, and 1 then place then one on the other, so
that the cut out part which is presented in relief to the surface of the metal plate on
which it has been fixed enters into the corresponding apertures in the portion left
intact. In consequence of this juxtaposition there is obtained a single block inked
in two colours upon which it is only necessary to press the sheets of paper in order to

device.
This process which I have described as applied to printing with two colours can
be applied to printing with as many colours as required.
I may also employ for the cutting out of the different parts of a design, and for
securing them any suitable process as may be required by the precise nature of the
material employed for forming the various blocks such as copper, zinc, steel
wood &c.
This process will be found very useful for chromolithography on porcelain, under
enamel, it being of course understood that it is applicable for all other kinds of
printing.

page_text: I, ADOLPHE JOSEPH BEJOT of Paris in the Republic of France, Merchant, 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 has for its object a new mode of printing chromo-lithographs
devised to supersede the long and delicate operations heretofore required to impress
the required layers of colour.
Heretofore after the stones, each one of which contains the impression of one of
the colours which is to form part of the chromo-lithograph, have been inked with
their special colour, the sheets of paper to be impressed are applied to the different

spond exactly at each impression by means of a mark in the form of a cross.

following process, which I will describe as applied to the printing of a design in
two colours for the purpose of clearly setting forth its details, reference being
made to the accompanying drawings in which
Figure 1. shows a letter cut out and fixed or placed upon a block on which it is
in relief.
Figure 2. shows the letter placed in the other portion of block in grooves or
apertures.
Figure 3 shows the block finally obtained by the juxtaposition of the two
letters.
Upon a metal plate of any kind or on a block, I draw say, a monogram or a
bouquet or any other design and afterwards cut out or remove that part of the
figure which is to be of a different colour in the picture from the remaining portion.
The portion removed is fixed in a suitable manner on a second plate of metal or
other material.
I therefore have now two blocks each bearing the part of the design which is to
be impressed with a different and special colour, each of these plates is inked sepa-
rately with its colour as in existing processes, and I then place them one on the
other, so that the cut out part which is presented in relief to the surface of the
metal plate on which it has been fixed, enters into the corresponding apertures in
the portion left intact. In consequence of this juxtaposition there is obtained a
single block inked in two colours upon which it is only necessary to press the
sheets of paper in order to obtain the impression in the desired two colours without
any adjustment or registering device.

page_text: This process which I have described as applied to printing with two colours can
be applied to printing with as many colours as required.
I may also employ for the cutting out of the different parts of a design, and for
securing them, any suitable process as may be required by the precise nature of
the material employed for forming the various blocks such as copper, zinc, steel,
wood etcetera.
This process will be found very useful for chromolithography on porcelain, under
enamel, it being, of course understood that it is applicable for all other kinds of
printing.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
The method of printing chromo lithographs in two or more colours without
transfers, which consists in the use of a block cut or carved so as to form any
suitable design, the part or parts of said block which are to be of a different
colour or colours from the remaining portion, being either cut or formed separately,
inked with the desired colour, and then replaced in grooves or apertures made to
receive them in the remaining portion which has been previously inked with its
respective colour, so as to form a single block with a flat surface from which an
impression in the desired colours may be obtained, substantially as described.
