(1) Diazo paper. Standard weight diazo paper produces a black or
blue image on a white background. Manufacturers produce diazo paper in
a wide variety, ranging in sheet size from 8 by 10 to 34 by 44 inches
and in rolls that range in width from 11 to 42 inches with lengths of 50
to 100 yards. Additionally, manufacturers also make diazo paper using a
colored stock, which provides a blue or black image on the colored
stock, and plasticcoated paper that produces a slightly glossy print
with better density than standard paper.
When you must produce many copies, the original you prepare tends to
fade and wear out after repeated exposure to the ultraviolet light. To
overcome this problem, produce a sepia line intermediate that serves as
a duplicate original. A sepia intermediate has greater density than an
original; therefore, it produces a darker image than the original and
withstands repeated exposure to ultraviolet light. You also can make
corrections to a sepia intermediate.
(2) Diazo foils. Diazochrome foils have a transparentcolored dye
image on a clear celluloseacetate film. Manufacturers make diazo foil
in a standard weight (.004 in. thickness) and two densities: (1) K
series, maximum density foils, and (2) Pseries, pastel densities.
