Russian Inventors Device That Prints
Six COIOrs Mt One Time.
From the London News.
The competition between authority and
roguery-the one striving to produce
bank note which cannot be initiated, ana
the other always seeking to initiate what
is produced. has led to a very remarkable
invention which is now being shown IN
London and which seems likely to revolu-
tionize the whole system of color printing.
For the origin of the invention one must
go to Russia. There it was desired to Is
sue bank notes and bonds by some means
that no forger could copy Accordingly
weaver's engineer was called in with the
idea that he should suggest sort Oh
thread that should be an absolute mark
upon paper. He brought an original nina
to bear upon the subject and innocently
asked why they could not find a printing
machine that would do what was wanted.
Why not? the skeptic was disposed 10
ask The weaver thought ii possible ana
finally designed a machine by which the
thing could actually be done. The RUSSIAN
notes and bonds are now printed by 1t,
with a success that the Russian govern
ment seems only too ready to acknowledge.
But Their a machine that will print an I'M
limited number of cOlorS at once cannot.
in these days of illustrated papers. be hid.
Hence it has been brought to London and
set up at 119 Shaftesbury avenue. where a
critical company had an opportunity OF
inspecting it in full operation.
1t is not a very large machine and, like
many other things of great utility, its prn-
ciple is simple. large color block, after
being rolled by it's own color comes IN con-
tact with a composition roller, where 1t
deposits its colors Each color block, in
short comes in contact with a transfer
roller on the whole of the picture, no mat
ter how many coiors is on the transfer
rotra of he n C.
ture is made to the printing plate. the
printing plate goes to the paper and the
picture is printed. But in another way 1t
may be said one roller. one color. Each
roller takes its special color to a transfer
roller. the transfer roller when 1t has re-
Ceived the whole of the picture transfers 1t
to plate, and the plate gives the impress
sion to the paper. A figure and floral IL,
lustration in six colors was being printed
the other day. The rollers having been
duly adjusted. the layer-on went to work,
feeding in at the rate of about 1000 per
hour, and the copies came out simply per-
feet.
Every printer knows that with six colors
there should. under the old system, be six
'machinings." ALL six coors were done
in one machining. The labor-saving was
there was no waste. Six machinings may
lead to a bad register which, to the
nontechnical means that in one or more
of the machinngs the colors may not meet
may overlap and the printing be thus
spoiled. The new machine will print at
one time in any number Of colors and with
out the possibility of work being thus
spoiled. Beautiful specimens of work
done is Russia for bank note and
bank purposes shown. Geo
metrical designs and work in tracery
We're especially good. . For bank
notes, checks maps and Illustrations the
process seems peculiarly adapted Rotary

that the system may be available in news
paper offices, with their great requirements
as to speed. 1t may be added that the new
method is the invention of Ivan Orloff, now
chief engineer and manager of the bank
note printing establishment of the Russian
government at ST. Petersburg.
