Test for Density Variation.

Density/DOT variation with time.

TEST:

• Expose a test to cassette.
• When you are in the dark room cut the film into 2 pieces.
• Keep one piece in a closed box.
• Develop the second piece immediatealy in the developing machine and write the value that you get - THIS IS YOUR REFERENCE.
• Wait until customer complains about the problem.
• Ask customer to develop the film that was left in the closed box.

If you get a bad result it means that the problem is with the Developing machine.

If you get a good result it means that this is a Dolev problem.

One limitation - If the film has been stored for a long time the results might change.
