Read Judy's "Annals of Gum Control: Part 1" in Post-Factory Photography,
Issue #1, and it's apparent that Judy was so hung up on the limitations of
the "gum-pigment-ratio test" that she just gave up on the test. It's
regrettable that she so harshly criticizes something that she does not fully
understand nor have experience doing.
IMO, the test is not based on a false premise. The test is very helpful
*for those who understand and accept its limitations*. I have used the
"gum-pigment-ratio test" extensively. The test data will point the gum
printer to a good 'starting point', where further testing can be done, using
sensitizer, step wedges, test negatives, and actual exposure. It is a
definite time saver when using new pigments.
