ny suggestions on the best way to prepare a PS Tiff grayscale file

GRACoL2006_Coated1v2.icc and then print to our Kodak Approval (which
converts using a device link). With some vendors the final is fine,
with some there's a slight cast we'd like to avoid. Since the press
varies depending on the client, I'm looking for a "universal" way.
Advice would be greatly appreciated.
They'll always look OK when you proof them because the proofer because
it's showing perfect printing conditions.
But using a standard profile will mean that you images get hosed every
time the printer loses control of gray balance - which is most of the
time :-)
You'll find quite a few double page spreads in glossy magazines that
have one page sepia and the other looking like a cyan/black duotone.
They indicate the clients who think that having a profile and a copy
of Acrobat replaces the repro guy in the production chain...
You need to create (or find) a profile specifically for 4 colour black
and white images which is based on the same characterisation data but
produces a nice long and wide K and very little CMY - making it much
harder for the printers to hose.
