For
more than 400 years after the invention
of printing, all type was set by hand.
By the 19th century, man began to con
sider the possibility of creating typesetting
machines. Numerous machines intended
to replace hand composition were invented.
Of all the various types of type setting
machines invented only two remained.
Machines such as the Linotype, Intertype
and Ludlow which cast metal slugs (one-piece
fully spaced lines); and the Monotype
which casts individual pieces of type
in justifi ed lines. The invention of
these machines took place in the early
1900". As late as the early 1960", these
machines were still considered "state
of the art" The machines used hot lead
to forge and mold type in slug or individual
form. After usage, the lead type could
be re-molten to be used again. During
the late 1960", com puter technology
began to take form with the development
of the com puter/fi lm system. Using
an electric typewriter with a special
punch tape unit, the punched tape could
be taken to a computer controlled processor.
Once the tape was fed to the pro cessor,
the punched tape would drive individual
photo one by one to produce a page of
text in another negative form.
It
was only a few short years ago, twenty-fi
ve to be exact, that the hot metal type
sys tems were "state of the art". Today,
these large hot complex machines have
been re placed by chips, computer monitors
and software leaving them for museums.
Then Today!
