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!
