CHAPTER XXI.
A FEW PRINTING PROCESSES.

After you have prepared your dummy and have de-
mned the kind of type and style OF stock to be used
decide what kind Of printing you DESIRE The usual
cess of pressing the metal type and plates against the
paper this FORM comprising the composition in combna
ton with the plates is left fiat and pressed against the stock
in that then the is known the or letter
press method
OF you have nothing to say the style of print
ing which will be given your layout of advertisement for
inclusion publication You must be content with the
they and with the colors they employ the making
of their printed product With the big newspapers this pro-
will be nodernized form of the etterpres method In
other words the metal form from which the impression to
be made will be transferred to cylindrical metal mold
Therefore, the printing will be done from cnder instead OF
from fiat form.
Usually the ordinary letter press style of printing is the
kind you want but when to duplicating piece OF adj
versng by the hundreds of thousands photography be
the most economical method to AS the term tho I'M
plies the main feature Of this science is stone which
the picture and type matter transferred This stone then
becomes the printing plate against which the paper pressed
Lithographic stones of peculiar composition. Most
these are imported Bavaria By keeping the stone wet
during the printing process all of its surface except that
which has etched by the transfer of picture and type
keeps damp and thereby repes the oily ink Consequently
when the passes against the ink roller only the surface
which make impression the paper takes of the
ink for the unetched part of the stone stays wetnd refuses to
take the ink.
Lithography is cheapest on labels and such small multi
coored pieces printed matter which must be duplicated by
the million In these cases. the big contain dozens
of reproductions of the design for the label whatever the
subject may be- Therefore great big sheet be printed
in one impression This when cut up will furnish hundreds
labels
you will look at piece of printed matter that has been
done by TYPOGRAPHY you will notice little This what
is called the register mark 1t is simply there to make sure
that the colors which put different Impressions
put accurately. For instance you have noticed how
poor photography human face will bear flesh color which
does not quite reach the edge side and which laps
beyond the outline of the face the other SIDE This is what
comes from inaccurate registering of the plates,
method, which is apparently gaining popularity
with those who want distinctive printing called the "ose
This accomplished either through photography regular
printing The idea that the stone the printing form makes
impression sort of rubber blanket which In turn makes
its impression the paper The result very soft effect
which resembles watered silk
The offset process also makes possible the of rough
to take the finest The for this
that the rubber blanket in making its impression the
paper will infinitely conform to all the microscopic crevices
the paper matter how rough whereas the plate
itsebeing pabewoud only impress Its likeness on the
high spots outstanding parts of the rough surface.
