The question is, with Under Color Removal, has the driver applied an 
internal ICC file first, or does it assume a specific profile has 
already been applied..?  In either event, is that the same profile as 
used for Full Color prints given the same paper settings...?

Here's why it matters...

If the driver is simply desaturating and then printing to a specific 
profile, altering/controlling where hues map along the grey ramp will 
only be possible if one converts to greyscale first.. However, if the 
profile the driver uses is actually mapping to the greyspace, then, one 
could conceivably use different profiles to simulate converting to 
greyscale from different channels...

Hope this digression doesn't make anyone too crazy..
