2. Make several test prints using an image that is typical for your
application, varying Dmax for each print.
When the blackest part of the image is black enough, stop and
go to the next step. Otherwise, adjust Dmax and make another
print.
3. Print the image as a gamma/contrast bracketing sheet job for
gamma and contrast.
It is recommended that you use the factory defaults for gamma
and contrast when making bracketing sheets. However, you can
leave them as is if you have already changed the default settings
to preferred values.
4. Examine the bracketing sheet and select the copy with the best
appearance.
If none of the copies are satisfactory, reprint the bracketing
sheet using the settings of the best copy. Repeat this until one
of the image copies is acceptable.
5. Set gamma and contrast to the settings used to create the
acceptable image.
6. Send a print job that includes various images that are typical for
your application.
Check the appearance of these images and make any necessary
fine adjustments to gamma and contrast until the images are
acceptable.
