The problem with quotes is that the context gets lost. The 
questions asked then were related to the PS>Qimage>QTR 
workflow and with the final print sharpening in mind. As 
Qimage only knows RGB it will do a sharpening on color images 
whether you give it greyscale or monochrome RGB. The output is 
always RGB. With the gradual steps in Qimage's print 
sharpening possible I do not find it to blunt but I always use 
low settings as I sharpen the greyscale image in Photoshop to 
the degree I like on screen and only add that last 
extrapolation + print sharpening in Qimage. My concern was 
that that last step could be better with greyscale specific 
extrapolation and sharpening and Mike couldn't see why there 
would be a problem as most of the effect is obtained on the 
luminance.
