Dear Yves, I think I mentioned this in the QTR forum as well . . . I suggest
using QuadtoneRIP as this gives you full control of the colorant amount and
placement. Richard’s neutralizing curve creator will work with those inks.
That’s going to get you the closest with a standard color ink set on an epson
printer. The key here though is that there is no real perceptually agreed upon
neutral. Everyone has a different cultural and internal neutral point.
D50-AB-at-0 neutral actually looks pretty green to most people. So you will
want to really tweak and tune it based on your paper and printing preferences
to make a more culturally acceptable “photo” neutral most likely. When I
formulated the Piezography Pro inks I went through 120 iterations of neutral
selecting a ton of silver prints for visual comparison as well as research in
what USA neutral was kinda like vs Europe vs South East Asia vs hue split
between OBA papers and non. I did not want to just choose some scientific lab
standard and stick to that because those generally don’t actually look that
good.
Regards,
Walker

Hi,
I'm curious to know if someone would have some suggestion(s) to create an ICC
profile of whatever type (device link, abstract, normal) for a RGB Printer
that would produce the best possible B&W print in terms of neutrality. I
suppose that neutrality must be defined in some way as well and suggestion on
how to verify that the print is matching the criteria we set as neutrality.
Thanks,
Yves
