First announcement OF the new

Arthur Hamerschlag, president Of
the Research Corporation, an or

sonian Institution at Washington,
D. c..
This printing machine operates
with great simplicity, Jehangir
Maneckji Cooper, publisher and in.
ventor Of the machine, explained
| in an exclusive interview with the
Cosmopolitan News Service the
principle Of his invention and how
placing it on the market would
effect the printing Of fabrics, wall
paper, fancy paper, posters and Oil
cloth.
! Method Very Simple.
my process is 30 very simple
chat several experts who have seen
! It, wondered why it hadn't been
thought of before" Mr.. Cooper
said. Present printing processes
are complicated. Printing as l do
it is simplicity itself.
There are several important as.
poets that make the machine en-
tirely different from any other now
/ In use. Most important perhaps Ia
the elimination of engraved metal
| cylinders. In my process any piece
OF lace, any piece of toweling or a
stencil-anything with a design in
slight relief, can be used as a
pattern.
1.-THE machine prints from any
thing pasted on the pattern-cylin'
der. To print blotch for instance,
it is only necessary to cut the pat
tern out Of paper or any similar
substance, paste 1t on the pattern.
cylinder and start printing at once.
Or a piece Of lace may be used
as the printing surface, producing
thousands Of yards with a delicate
webby design of real lace. A piece
Of lady's yelling dyes the ground
and prints the pattern in one sin
gle process. Or again, the artist
or designer can create his sketch
right on the pattern cylinder with
some paint. When 1t Ii dry the
print can be made from the orig.
lnal sketch itself. In fact, the de-
signer is his own engraver.
by my process the printing
surface is not at all colored or
linked. My color bex is arranged so
that 1t is a question Of scraping
rather than rolling the color onto
the color cylinder.
Gets Graduated Tones.
I'm the ordinary printing process
the engraved cylinder is covered
with dye and then scraped off, leav.
ing the color only in the engraved
sections. In my method the pattern
Is placed in back Of the textile to
be printed, and the color cylinder
uniformly linked meets the textile.
The slight pressure exerted causes
the fabric to pick up the ink wher-
ever the design pressing from in
back is in relief. BY this method
it is easy to get a graduation Of
tone from a perfect white to an alb
solute dark, on the principle that
the higher the relief, the darker
the tone, and the lower the relief,
the lighter the tone.
| Another feature Of this new ma.
chine, Is its ability to print a de-
sign Of any length, without the use
OF costly intermittent machine. Sup
posing the circumference Of the
pattern cylinder is only fifteen
inches-this does not prevent the
| printing Of an Indian Sarong, which
Is eight yards long. In all the eight
yards there is no repetition Of the
design. The whole can be run
through like an endless belt.
Whereas the intermittent machine
prints usually in multiples Of nine
inches, the endless belt prints any
length.
"The possibilities Of this machine
| to my mind are numberless. When
1t is thoroughly understood that the
| pattern may be made from any sub.
stance, however soft or smooth or
| rugged 1t may be, one can perhaps
| understand that an almost infinite
number Of designs may be put upon
the market at a trifling cost.
Then, too, the fact very little
pressure is necessary by my process
makes It possible to print upon the
l
| without Furnishing the material.
Such printing If done at present
must be done by the hand blocked
method, a very expensive process
with limitations. It cannot, for in
stance, print a lace pattern.
Prints ON Rubber.
"In addition to printing on fabrics,
oil cloth, paper, ETC., it can also
print on rubber with rubber solu.
ton. That is something no other
machine has been able to do. In
the same way / have used pyroxotin
as a medium for printing on leather
! cloth. Pyroxotin is celluloid
product which has not been prac-
tically used in printing.
Altogether, / believe that my
method will revolutionize textile
printing. Some. time, moreover, I
may be able TOT adapt 1t to letter
printing as well. Even now it can
reproduce typewriting that has been
done on blotting paper"
Cooper hit upon the invention by
accident. He was trying to make
his own bookbinding cloth, when
In the process of making half
| tone print, one of his printers turned
the engraved block one way and the
overlap the other. The result was
two Impressions. Mr.. Cooper then
wondered whether the engraved
block could not be completely clint
mated. Ten minutes later he took
an ordinary piece of gunny sack
and usisg 1t as a pattern obtained
an interesting design. Since that
day, In 1918, Mr.. Cooper has been
