(8) After completing the necessary test and corrections, you should
be able to make good contact sheets.
c. The procedure for making contact prints, using a printer such as the
EN22A, is quite different from that described in paragraphs a and b.
(1) Clean the printing area.
(2) Connect the timer to the printer and then to the proper
receptacles. Place all the printing light switches in the ON position.
Check the viewlights and the safelights in the printer for proper operation.
Place the master switch in the OFF position and check the operation of the
platenactuated pushbutton switch.
(3) Clean the negative(s) to be printed.
(4) Place the negative(s) with the emulsion side up on the glass of
(5) Turn off all white room lights.
(6) Judge the contrast of the negative.
(7) Select the proper filter and you will be ready to make a test
d. The procedure for making a test strip is as follows:
(1) If you are making a contact of only one negative such as a 4 x
5inch, then cut a sheet of paper into test strips approximately 2 inches
(2) Choose the area of the negative to be used for exposing the test
strips. The area for the test should contain highlights, middle tones, and
shadows. The same part of the negative should be used to make each test
(3) Make a series of test exposures using a normal contrast filter.
Use a systematic method of exposing. For example, you can start with 2
seconds and double it each time, or another method is to expose each test
with an equal amount of increase. The idea here is to bracket the correct
exposure; that is, to go from underexposure to overexposure.
(4) Inspect the test strips and determine the best exposure.
(5) When the best exposure has been selected, determine if the
correct contrast exists.
