I wonder about the Eclipse since it always gave a lower Dmax but the UC
seems to respond very differently than earlier inks so I guess it is back to
ground zero as far as testing this stuff out. I suspect that if Eclipse does
go away, which looks very likely as they are not shipping any paper at this
time, it will be back at some point.

That is very true and I do tend to forget about the glossy side of inkjet.
Something I would reconsider if they could come up with a paper that did not
have an "RC" look to it.

All the PT wedges I sent were done using a CIS. I don't seem to be having
any problems printing with them but others report they do. As far as the PT
grays go I think it is a cart and software issue but usage is perhaps still
too new to be sure we have seen all the problems.

Sounds good.
