The Ziegler Magazine's embossing plant was by far the largest
in the world. One estimate indicated that it could turn out in one
day as much work as would require 320 men and 140 machines by the methods then used in England. Indeed, if the
English method had been used to produce the Ziegler, a single
month's edition would have kept two men and one machine busy
for two years. The magazine was revolutionary not only in its
conception, but also in its manufacturing techniques.
At first, raised-dot reading materials could be embossed on only
one side of the page, since there was no way to emboss dots on
the second side without crushing the first set of dots. This remained true in the United States until the 1920's. But as early
as 1914 the Ziegler plant had constructed ingenious machinery
for two-sided (interpoint) printing that halved the bulk of each monthly issue. While the dots produced were not of a
high-enough quality to be used for books, they were perfectly
suited to something as ephemeral as a magazine.
