An Invention More Wonder ful Than
Wireless Telegrauhy.
More wonderful than wireless teleg-
rsphy is the discovery of a mode Of
printing without the employment OF ink
orany Iifment whstever. The process
was accidentally discovered by Mr..
Friese. Greene, who was working in his
laboratory e2dea7oring to perfect a
PROCESS for the reproduction Of photo
graphs in natural colcrs. The process
as described in the last number Of the
American Press is Interesting.
1T would seem thst in the last dis
covery had baen found that long sought
desiderstum Of the ancient alchemists,
the great srcsnun>" or art Of trans.
mutirg metals, for the different coloEs
in this inkIess printing process are pro-
duced b. using different metals for
types. Thus the action Of electricity
upon types OF blocks Of copper produces
q green Impression; brass, brown; z!nc,
yellow; geld, orange; aud by tresting
the paper With potash the inventor IS
able to print in red from types faced
7ith silver. All these oolors can be
produced at The sams tina and with
rspidity exceeding even the rate at
which newspapers are turned of the
prsss by present processes. Photographs
may be Reproduced without interVen-
ton Of 8 screen" and with all the eX
ouisite detail to be seen in the original.
Il will rot be long before our msga'
ziues and newspapers will ba brought
out beautifully illustrated in colors and
at cost much. less than st present, oW-
ing not only to the saying il inks aud
in attendance, but to the rspidity with
which the inkless machines may be op.
Grated. Electrical printing machines
c.n be run, the inventor claims. at a
much greater speed than the present
dsy perfecsing presses, for the 40 ion is
so quick that strong, clear impression
is produced by the contact OF type with
paper during even a thoussndth part Of
sseocud.
The only radical departure is in the
presses, the ink rolls being done away
with entirely. SO thst the necessary
amount of time and labor involved in
their preparation snd cara may be av-
avoided. The invention.nay be adopted,
it is said, to any machine ct present
used, which may be converted into one
for electrical printing without any great
change OF expense, it being necessary
only to remove the ink rolls and make
the electrical connections and, Of
course, 10 use the newly invented types.
The neR printing machine is simple.
compact and inexpensive as compared
with the intricate presses nov in use
and can be set up and operate d Where7.
er sufficient electrical power is avail
able.
The discovery that electricity might
prove directly applicable to printing
wss made accidentally, in the came
manner as many other great inventions
have come about. Mr.. Friese Greene
the inventor, was working one night in
his laboratory-for he has been long
time experimenting on process for
color photography and has become
known through his scientific research
es-ald accidentally placed a silver
coin ca s piece of white pspsr which
was resting on a sheet OF tin. The tin
plate hsppened to be connected with
the positive pole Of an electric battery,
and the coin Glanced to be touched By
the negative wire. Upon removing the
coin a perfect impression was found
printed on the paper.
The experiment was repested again
and again, always with the same result,
an exact reproduction in every detail Of
the original printed in black. Per
ceiving the great possibilities in this
accidental discovery, the ezperimenter
abandoned all other work and devoted
himself uuremistiDgIy to solution OF
the problem 50 unexpectedly presented.
Asssr many weeks Of experimentation.
t. sting different papers imDregnsted
with various chemicals and usisg sew
ersl metals, hs at last perfected his dis
co7ery snd not only obtained perfect
Impressions in black equal TO these Ero-
duced with tie best inkB, but, by using
different blocks os metals, actually
printed any color desired. By Coating
the portion Of the blocks where red is
required With silver the REQUESTS effect
is obiained, with copper for green,
brass for yellow. gold for crarge, etc.
