Strasbourg, 53. "AN IMPROVED MODE OF AND APPARATUS FOR PRINTING SIMUL-
TANEOUSLY IN SEVERAL VARIED COLORS NEWSPAPERS, MAGAZINES, AND OTHER
PUBLICATIONS OR WORKS."
This Invention has reference to a mode of and apparatus for printing simul-
taneously or at one and the same operation in two or more different colours on ono
or both sides of sheets of paper. For this purpose I provide in the printing
machine as many printing cylinders with duplicates or clichés of the type as there
are differently coloured impressions to be produced, each such type or cliché having
only that part in relief upon it or otherwise in condition for receiving the ink that is
required to be printed of its particular colour, so that the combined impressions of
the several cylinders will represent the complete page or sheet of printed matter.
Each such printing cylinder is provided in the usual manner with a pressing
cylinder and with an ink reservoir from which the ink is supplied by means of
delivery and spreading rollers.
The several pairs of printing and pressing cylinders are by preference_ranged
in line so that the paper will pass in a straight line through them, and they are
arranged with accuracy in position relative to each other so that the paper, after
receiving its impression from one printing cylinder will, in passing through the next
cylinder, be printed upon thereby at the exact points where the particular colour
may be required, whether this be, for example, a line intermediate between two
lines of type printed by the preceding cylinder, or one or more words or letters
intermediate between two words or letters printed by the preceding cylinder, or a
13

page_text: part of a letter or design, the other part or parts of which is or are printed in
different colour or colours by the other cylinder or cylinders.
It will be evident that this Invention is readily applicable to various con-
structions of printing machines at prosent in use, it being only necessary to
provide the same with as many duplicate sets of type and ink reservoirs as there
are different colours required for either one side only or for both sides of the
paper.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Emile Vauthier in the Great Scal Patent Office on the 2nd October
1876.
EMILE VAUTHIER, of the Firm Emile Vauthier et Co., of Paris, Boulevard de
Strasbourg, 53. "AN IMPROVED MODE OF AND APPARATUS FOR PRINTING SIMUL-
TANEOUSLY IN SEVERAL VARIED COLOURS NEWSPAPERS, MAGAZINES, AND OTHER
PUBLICATIONS OR WORKS. A communication from Jacob Worms, residing at Paris,
Rue Sto Anne, 42.
This Invention has reference to a mode of and apparatus for printing simul-
taneously at one and the same operation in two or inore different colours on one
or both sides of sheets of paper. For this purpose I provide in the printing machine
as many printing cylinders with duplicates or clichés of the type as there are
differently coloured impressions to be produced, each such type or cliché having only
that part in relief upon it, or otherwise in condition for receiving the ink, that is
required to be printed of its particular colour, so that the combined impressions of
the several cylinders will represent the complete page or sheet of printed matter.
Each such printing cylinder is provided in the usual manner with a pressing cylinder
and with an ink reservoir, from which the ink is supplied by means of delivery and
spreading rollers.
The several pairs of printing and pressing cylinders are by preference ranged in
line, so that the paper will pass in a straight line through them, and they are
arranged with accuracy in position relative to each other, so that the paper after
receiving its impression from one printing cylinder will in passing through the next
cylinder be printed upon thereby at the exact points where the particular colour
may be required, whether this be, for example, a line intermediate between two
lines of type printed by the preceding cylinder, or one or more words or letters
intermediate between two words or letters printed by the preceding cylinder, or a
part of a letter or design, the other part or parts of which is or are printed in
different colour or colours by the other cylinder or cylinders.
It will be evident that this Invention is readily applicable to various constructions
of printing machines at present in use, it being only necessary to provide the same
with as many duplicate sets of type and ink reservoirs as there are different colours
required for either one side only or for both sides of the paper.
The principle of this Invention is the application to colour printing of the system
of printing machines known as perfecting machines, which print both sides of the
paper in one colour, and which for the purpose of this Invention is modified so As
to print upon one side of the paper in different colours. For this purpose there is
no change of importance to make. It is sufficient that each ink reservoir should
contain ink of a different instead of the same colour, that the forms should be divided
in such manner that the parts when put together constitute one complete impression,
and that the rollers should ink only that portion of the form which is to be printed
with a particular colour.
The travel of the paper in the press has to be so modified that it receives two
impressions upon the same place; the modification is however not necessary if
it is desired to print with a single colour on each side.
My system of printing rapidly and simultaneously in two or more colours may be

page_text: applied to known kinds of printing machines, such as those with pressing cylinders
or plattens, the machines with large type cylinders, and roller machines with cylin-
drical forms. I employ by preference machines of the kind last mentioned, which
are generally used for journals of large circulation. These are best adapted for the
manifold combinations for printing in several colours, whether at one side only or
on both sides of the paper. This machine effects the printing by means of a cylinder
carrying a form or cast of the type revolving in contact with a pressing cylinder,
and supplied with ink from a reservoir.
For printing in several colours the machine has as many ink reservoirs and pairs
of type and pressing cylinders as there are different colours, but the printing may
nevertheless be effected with a less number of colours than that for which the
machine is adapted. Thus, for example, if a machine has eight pairs of cylinders
and eight ink reservoirs for printing in four colours on each side of the paper, then
the printing could be effected in two colours only on each side by putting only four
of the cylinders and ink holders into operation; or one side might be printed in
two colours and the other in one by using only three pairs of cylinders and their ink
holders; or cach side might be printed in one colour by using only two pairs of
cylinders with their ink holders. In all cases the forms or casts are divided, so that
the several parts when put together shew the entire polychromic impression. Among
the various colours may be included gilt or silver lettering, or bronzing with
powders; thus for gilt illustrations the last impression can be made with a mor-
dant, the metal powder being applied to the paper as it issues from the press.
In the accompanying Drawing Figs. 1 and 2 shew two arrangements, one
horizontal and the other vertical, of a roller press, arranged for the application of
my process of simultaneously printing in several colours. The horizontal arrange-
ment, Fig. 1, has altogether six pairs of cylinders A, B1, A2, B, &c., of which the
touching points all lie in one and the same horizontal plane, which represents the
path of the sheet of paper. The outer pairs A, B, A, B, print on the back of
the sheet, and those A, B, A³, B³, A, B, A, B, on the face. The two cylinders
of each pair consists of a pressing cylinder A' clothed as usual with a blanket, and
a form cylinder B¹. The forms are held on the cylinders by means of fixed or
moveable grippers, in order not to damage the impression. The cylinders B have
in relief only the part or parts of the forin which they have to print. At the side
of each form cylinder is the inkholder C, with its supplying roller c, distributing
rollers f, f, and applying rollers g', g'. The press shewn in Fig. 1 is arranged to
print continuous paper, which is unrolled from a roller H, and is directed by incans
of guide rollers between the two cylinders of the left-hand pair, where it receives its
first impression. The paper then passes successively between the second pair, and
then to the third pair, and so on, each impression being in a different colour as
indicated by the hatching of the inkholders.
On issuing from the last pair of rollers, the paper is cut into lengths in the usual
way. The machine shewn at Fig. 2 differs from the preceding one, mainly in the
position of its cylinders, which are arranged vertically instead of horizontally;
There are four pairs of cylinders, the form and pressing cylinders being arranged
alternately on opposite sides, so as to print in two colours on each side of the paper,
which is supplied in separate sheets, which are seized in the ordinary manner by
grippers not shown in the Drawing, and introduced between the first pair of rollers
whence they pass to the second pair, and so on. The number of pairs of cylinders
may be varied according to the number of colours which the machine is intended to
print. Also the form cylinders may be arranged on one side, if the paper is to
be printed on one side only with various colours.
In all cases the spaces between the cylinders must be determined with precision,
in order to give a perfectly exact register.
The vertical arrangement shewn in Fig. 2 is convenient for printing journals on
both sides in different colours, but for wall papers, stuffs, geographical maps, and all
objects printed on one side only, it is preferable to arrange the machine horizontally
as in Fig. 1. For printing a journal in six colours, six completo forms may be used,

page_text: each having in relief only the parts which are to receive the particular colour, tho
other parts being sunk or covered in. For printing a book (such as a dictionary)
in several languages and several colours, a single cast or form may be made and
the columns being separated after casting a single column can be fixed on each
cylinder.
Having thus described the nature of the said Invention and in what manner the
same is to be performed, I claim,——
First. The mode substantially as herein described of printing on either one or both
sides in colours, by passing the sheet continuously between successive pairs of
form and pressing cylinders, each form cylinder having in relief only such part of
the form as is to be printed, with the particular colour supplied to the said
cylinder.
Second. Arranging the successive pairs of cylinders with their respective inking
gear, so that a continuous sheet travels through between them horizontially, sub-
stantially as described in reference to Fig. 1. of the accompanying Drawings.
.
Third. Arranging the successive pairs of cylinders with their respective inking
gear, so that successive sheets travel through between them vertically, substantially
as described with reference to Fig. 2 of the accompanying Drawings.
In witness whereof, I, the said Emile Vauthier, have hereunto set my hand
and seal, this Eighteenth day of September, in the year of our Lord One
thousand eight hundred and seventy-six.
