Digital BW, The Print

The good thing about Roy Harrington's QTR/UC approach is that it shuts
off the yellow channel completely and you can do that with Studo Print
and Bauhaus. At that point with Ultrachrome the worry is the Magenta,
and especially the light Magenta. Those ARE going to change
eventually. Apparently the cyan channel is very durable.
