Hi Thomas,
first, i would congrats to your FD-9, i had the privilege to test this
exceptional device, and both speed and accuracy of the measurement are
really great.
Regarding targets - as friends wrote in recent emails, it depends how
you will print on the printer. If print through OS drivers, typically
from the Photoshop, then the printer is behaving like RGB device and
you have to use RGB target and RGB profiling. These 11 inks will be
"mixed" by the driver itself.
If print through RIP, it depends on the RIP itself. Per example, EFI
will allow you to decide, whether you want profile printer as CMYK or
RGB (for many printers, include yours).
In my experience, you can start with RGB targets, with P7000 and
decent paper you will get very good results. CMYK profiling can bring
somewhat better results but is much less straightforward. I do not
recommend any attempt to 11 inks linearizing/profiling, as this can
introduce solid pain.
Best,
Kamil

Hi,
first a quick intro: Name is Thomas, i work with Stuttgart Media University
and my job there is to wath ink dry. I specialise on gravure
printing, amongst other stuff that includes advanced tinkering with al kinds
of electronic devices to better understand waht happens when
ink hits substrate.
Recently, we have acquired some new tools for our labs, namely the P7000 with
ultrachrome inks and a Minolta FD9 scanning spctrometer. While
we're at it, i figured i might try to better understand what's happening
within icc color mgmt, and to better know argyll by trying to
profile the P7000.
Has anyone tried to do this before?
I crashed on the first wall generating a target, since argyll seems to have
an eight colour limit, but the P7000 uses 11.
The colour palette we use (and the designations) are:
C Cyan
Y Yellow
PK Photo Black
LK Light Black
MK Matte Black
OR Orange
GR Green
V Violet
LC Light Cyan
VM Vivid Magenta
VLM Vivid Light Magenta
There's another Palette, where V is replaced by LLK Light Light Black
Is there any chance on getting argyll to work with this?
best regards
Thomas
