Digital BW, The Print

Hi Carolyn,

Your points are well taken. I went ahead and made a new version of the 
profile using No Color Adjustment (NCA) and it worked fine. If you'd 
like a copy let me know. The new version of the profile suppresses 
dots as well. I'll see if I can get the new version posted. 

Again, if anyone else would like a copy of the profile I'm happy to 
distribute it (for the Epson 1160, Full Spectrum Quad Tone, Epson 
Enhanced Matte). The greyscale tones are still not correct because I 
don't have a Q60 target, but it's relatively close.

[ As an aside, scanner-based profiling (which I use) can't profile 
bronzing (excessive ink deposition) because bronzed colors just look 
like black (or something close to it). Unfortunately, choosing "No 
Color Adjustment" can put too much ink on glossy paper, causing 
bronzing. Fortunately, B&W printing uses matte paper so bronzing isn't 
an issue. I'll stick with "No Color Adjustment" until I have a reason 
to change to another setting. ]
