Terry,
Are you finding any visual differences between the recent Epson's and the
HP's, say, both calibrated with GMG on the same substrate to the same
specifications/standard?
Sorry to put you on the spot.
Best / Roger

Yes, sort of. I would call it an "add-on" whereas the HP "Z" series printers
truly have an internal spectro.

I don't know about *ONLY* with RIPs....but it works very well with RIPs that
support this feature.

AFAIK, no, there's no way to store an internal calibration. The HP "Z"
series can store an internal calibration but it's more of a linearization
than it is a colorimetric calibration (only "calibrates" the pure ink
channels but does not do any sort of hue correction that I know of).

GMG Colorproof....it will start with a master calibration target and then
create printer-specific calibration files. You specify the dE tolerance you
would like to hold for all the printers and, optionally, set them up on an
automatic calibration schedule. There's an upper limit as to how many
printers you can manage from a single box (generally 4's the limit) but you
can certainly install the master calibration file on to multiple GMG RIPs if
necessary.
I've done many GMG+HP z2100/6100 installs and just did my first GMG + 2 x
Epson 9890+Spectroproofer install a few weeks ago and it just works.

Terry Wyse
