(2) develop continuous-tone copy to slightly less than normal contrast.
b. If light areas of line copy show fog, they may be treated with R-4a, Farmer's Reducer.
Learning Event 4:
MAKING THE PRINT
1.
Making the prints.
a. The principal difference in types of copy prints is that line copy has very high contrast and
continuous-tone copy has a normal range of contrast.
b. As we mentioned before, some originals may contain both areas of line copy and areas of
continuous-tone copy, such as a picture alongside printed text. These are best copied by making two
exposures, one on line copy film, and the other on continuous-tone copy film. Then the two negatives
are used to make one print by one of the following methods.
(1) Method one as shown in Figure 3-11. Mask the portion of each negative that will not be
used, then expose the print twice, once with each negative. This is not a double exposure because the
masked areas of the negatives keep light from striking the print. Carefully align the print paper and each
negative in order to get the line copy and the continuous-tone copy into the proper position with respect
to each other on the print. You can do this by hinging or taping the negative edges together.

(2) Method two as shown in Figure 3-12. Cut away the unwanted parts of both negatives so
the two negatives can be taped together to form one. This is called splicing or stripping. You may use
red cellophane tape for opaque areas but you must use clear tape for transparent areas.
