If this problem is caused by having set the D-Max targets too high in the Balance
program, then the solution is to find the best D-Max targets that will work with your
material.
To find the proper D-Max targets for your material, do the following:
1. In the Chromira Printer program, go into the Emulsion dialog box. At the
bottom of this window, locate the color balance settings for the Emulsion.
These are the Cyan, Magenta, Yellow, and Density values.
2. Add 200 to the Density value, and enter this new number here. This will
drive the printed image into the D-Max failure zone, which is what we are
looking to do for this test.
3. Close the Emulsion dialog box, and run a Test Print in the normal manner.
Process the print when the Chromira finishes it.
4. Looking at the resulting Print, you should see that at least the top few
patches look like they are all black. If they do not, then increase the
Density setting in the Emulsion dialog box even more, and try another
print.
5. On this D-Max Failed Test Print, take a densitometer reading of the
darkest black, which should be at Patch Zero (0). Write down the
reading’s three values (R, G, B).
6. Subtract 7 to 10 points from each of the values that were read in the
previous step. Write down these values. These will be the D-Max Targets
to be used in the Chromira Balance Program’s Densitometer window.
7. Important: Go back into the Emulsion dialog box in Chromira Printer, and
set the Density setting back to it’s original value, after you get a
well-blown print.
8. Run a couple of Balance cycles, where you only do the Densitometer
analysis. Do not scan the image during these cycles.
9. After two or three more prints, the Test Print’s grey scale should have all its
patches at nicely spaced density intervals. Once this is achieved, you
