<However with IP it seem in some cases we almost always get snagged with
images and pages that have content that is made up of grayscale and
color images.>
Not sure I understand. If you layout 2 images on the same page, one is
greyscale gamma 2.2 and the other is say AdobeRGB, and you choose a
color profile lets say Epson Enhanced Matte 1440, you are printing both
images through the color output profile. Obviously the grey balance of
the greyscale image is at the mercy of the color profile quality. This
isn't the best B+W that ImagePrint can do if you are using the
2200/7600/9600UC printers. I don't know what printer you are using but
if you can separate the greyscale from RGB files in the workflow, using
the grey profiles will give you the quality far better than any other
RIP that is simply using a standard ICC color profile to print B+W.
<The neutral shadows turn some weird color such as green or magenta,
even after hours of fiddling with profile editing or the IP color
tools.>
If I print gradients I can't find anything other than smooth transitions
with no crossover. Sounds like the profile isn't working well for you.
Do you have a custom one or are you trying to tweak a Colorbyte profile.
<What is interesting about this method is that grayscale prints stay
neutral gray under different lighting conditions. You cant do that with
an RGB workflow.>
Nobody prints better B+W than ImagePrint using their grey workflow, and
the metamerism is very low. I can't even find another RIP that does B+W
close to IP. There is no reason to print greyscale images through a
color profile, that's what everyone else does and it stinks in
comparison.
<Also, when you have the right rip with linearization options you can
re-linearize so there is a potential for less re-profiling if something
in the process changes. That not an option with IP.>
This to me has always been a bit of a stretch with the inkjets and has
very limited usefulness in reality. The Fuji Pictro the calibration
works great and makes sense. If something in the inkjet "process"
changes (ink color or density, or changes to paper coatings) than you
might as well create a new profile anyway because re-linearizing won't
correct any of that properly.
