Neil:
I agree with you, the profiles built with the internal profiler are darn
good...
but have nothing to do with Monaco or X-Rite. They are done with
technology 100% developed inside HP. Vancouver and Barcelona.
However, who would trust HP's profiling tecnology? Very few. That's
the reason why APS was added, as an accessory, to the Z-series printers.
It was not a technical decision, but a commercial one.
APS is an entry level profiler, with a simplified UI, which implies it is
not using all the potential of the X-Ryte profiling, for the sake of
simplicty.
Actually, the same is true for the HP profiler (that you call Color Center).
And there was a whole SDK developed, to give you access to the profiling
engine inside the printer.
The slight problems you see with those profiles have to do with the fact
that the Z-series printers support several color pipelines, and yet, the
same
profile has to be used from the driver and produce similar color to the
color
printed with the internal LUTs (different tool, different color
separations...).
Whether that has changed in the last year and a half, and in fact what
you say
about Monaco profiles is true, I don't know, and I'll give you the
benefit of
the doubt. But a very small doubt ;-)
Cheers,
Ignacio
