ALBERT JULES SCHLUMBERGER, of Paris, Boulevard de Strasbourg, 23, Manufac-
turer. "AN IMPROVED CHROMO-TYPOGRAPHIC PROCESS OF AND APPARATUS FOR
PRINTING ADVERTIZEMENTS ON NEWSPAPERS AND OTHER WORKS."
In the improved system of chromo-typography which I have contrived, and which
forms the object of the present Invention, the object I had in view was principally
to cause certain advertizements and announcements in newspapers, journals, and the
like, to appear more bold and striking to the eye by an impression partly in
colours.
I obtain this result in the printing itself or working off of the newspapers without
going over a second time, by the addition to the usual printing presses of an
arrangement comprising type cylinders and supplementary colored inkers, in a
word, the appropriate apparatus necessary for printing in one or several colors.
The other parts of the press remain the same as for ordinary black ink printing
on the 1st and the 4th, the 2nd and the 3rd page of the paper. The object being
simply to attract attention to certain advertizements without disturbing the general
appearance of the journal or newspaper; the coloured impression is only moderately
used.
During the printing in black I set apart certain titles or headings for printing in
colours, or again leaving the impression in black, as it is usually. I cover the position
of the advertizement with a chequered, dotted, or other ground. I may also sur-
round the advertizement with a coloured border, or apply any ornamentation,
embellishment, trade mark, or design to it calculated to show up the advertizement.
As before stated the coloured impression is made simultaneously with the black
impression, the margin being fixed once only. The marks of junction are made by
the ordinary means, but to facilitate the concordance between the black printing
roller and the coloured printing roller I divide the periphery into several corre-
sponding segments, which I number in the same order. In this manner the por-
tions of the coloured type which are to correspond to the advertizements to be
ornamented may be more easily fixed and renewed.

page_text: The existing presses are admirably adapted to the accomplishment of my system.
It will only be necessary to indicate by way of example two distinct kinds of presses
appropriated to my Invention. In one of these there is but one cylinder press,
around which are grouped the type cylinders with their respective inkers. To the
cylinders which print the 2nd and the 3rd, the 1st and the 4th page in black, two
other cylinders are added, intended to print in red and blue, for example.
Another style of press is derived from the "Derrier" system, which carries two
pairs of type cylinders and of cylinder presses, the first pair printing on the 2nd
and 3rd, and the second pair on the 1st and 4th pages.
I arrange my supplementary apparatus at the front part, composed of a type
cylinder, and of a cylinder press, between the two are the coloured inker and the
distributing rollers.
The other parts of the press need not be described as they present no particular
feature. I will only observe that I may print on endless paper, or on sheets, by
utilizing for that purpose the cutting mechanisms which are employed either in
typography or in chromo-lithography.
I may modify the details of construction of existing presses when appropriated
for the putting of my system into practice.
