Well there may be other variables in my system, but I get fewer
artifacts sharpening the reduced TIFF rather than the JPEG.   I may
need to experiment with lower USM settings on my JPEGs, but given my
scanner's good somewhat limited capabilities (FS2710) , I'm very happy
with the workflow of TIFF>resize/resample >sharpen>compress.
