Subject: Photocopiers

From a damage perspective, edge copiers are just as risky as center
glass machines. The risks to bindings occur as the book is repeatedly
flipped into a face-down position. The edge copier complicates this
handling further with the dangling portion hanging from the edge. In
comparison with these manipulations the flat opening press-down on a
center glass machine is relatively safe.

At this point there are also some production advantages with a center
glass, including the ability to extend the gutter margin and print in

The fundamental problem, relative to work from bound books, with all
copiers and with scanners to come is their face-down working
configuration. The face-up configuration, as in filming, is better for
bound books.

Best wishes,

Gary Frost
