Martin,
Terry's point is valid, and by not responding directly to his point you are
just dragging the issue further. Terry and myself and I'm sure a host of
others on this list all well understand Fogra. We're not debating Fogra's
tolerances but we think you are citing their numbers in the wrong context.
All we're saying is that, Fogra or not, the proof has to be within a close
range of the Fogra or SWOP or whathever reference dataset. How well the
press is able match that is another issue.

Depends what Lee is being held accountable to. Separations made for the
Fogra dataset and separations made for SWOP TR-001 do not match each other,
to my knowledge, even if, at the root, both are based on a common inkset,
defined in ISO-2846.

You seem to be having the right approach, for your clientele.
