Copying transparencies. There are two methods of copying transparencies, the indirect method
and the direct method.
a. In the indirect method you use the transparency as you would use a negative to make a
contact or an enlargement print. The print may be made on either film or print paper. In either case the
result will be a negative of the transparency. If you use film, you need to repeat the process to get a
negative of the negative or a copy of the transparency. Use a commercial or commercial matte film. If
you use print paper, then you must photograph the print to get a negative that will be a copy of the
transparency. The indirect method of copying transparencies uses a film with a solarized emulsion. A
solarized emulsion produces the opposite result of a normal emulsion. That is, a solarized emulsion
produces a clear or light area where the light strikes the emulsion. Thus, a positive or direct copy can be
made with a normal printing process, using the transparency as you would use a negative and the
solarized film as print paper.
b. Direct reflex copying.
(1) There are many ways you can make direct (scale 1:1) copies. A photographic method of
direct copying is called reflex copying. The main advantages of reflex copying over other forms of
direct copying are durability and sharpness of the image. Direct copy film, however, can produce as
sharp or sharper results than reflex paper film. The scale in reflex copying is 1:1.
(2) When the original is translucent and printed on only one side, copy prints are made
directly on flex copy paper by a contact printing process (fig 3-13). The original is placed face up on top
of the reflex copy paper and exposure is made by shining light through the original.
