Joe,
Your problem is a common one with 35mm scanners. The relative densities of
the target's shadow patches are being scrambled by by optical flare in the
scanner itself. The problem is even worse in Nikon 4000 and 8000 scanners.
Monaco senses a high initial error between scan densities and reference
CIELab values and rejects the target file. You can expand Monaco's
acceptance window by editing a file in the Application support folder under
OS 9, but it won't solve the original problem.
I am expanding the HCT instructions www.hutchcolor.com/HCT_instructions.htm
to explain how to minimize the effects of flare in 35mm scanners. E-mail me
privately and I'll send you a draft of the anti-flare notes, which are not
yet in the main document.
Regards,
Don
