CA is common on the Shadow unit, misregistered printing as part of the technicolor process usually presents quite differently, and the one-light transfer is responsible for the crush.

Do you still have the print BTW? i.e. could it be scanned again?

I have never heard that and don't understand how that could be. The Shadow is a line array scanner, like the Spirit- so there would be no ability for misaligned or color creep of any kind really. I would be interested in seeing how CA is common on the shadow, as I can't find anything to suggest that. What is clear is that particular shots vary in alignment on the 1971 print. :)
