100 Years Ago: Whitest Printing Plant in the World

May 1908
Magazine for the  Blind - "Undoubtedly the whitest printing plant in the
world is that in which the Ziegler Magazine for the Blind is published. The
reason is obvious. No type is used, and no ink of any description is to be
found except, of course, in the editorial room. The monthly magazine is
circulated without charge to any person in the United States or Canada who
can read the point alphabet. In the composing room of the plant there are two
machines, one of which makes the plates for the New York point edition, while
the other serves for the American Braille edition. Very unfortunately, both
of these point alphabets are in general use in the country."
