Andrew,
You say:
The printer and display "APS's" are two separate products for now. Yes it
would be nice if one worked with the other, and yes we are aware of
that....
I did not think you were not aware of it ;-)
but now it is also very clear to me. Ah, product engineering is full of
challenges!
Thanks for the very complete answer.

The APS for the Display is the:
HP DreamColor Advanced Profiling Solution KZ300AA
Price: ~$350
Quick Summary: Primarily provides the ability to profile and calibrate the
lp2480zx display, update calibration in formation in the display and
create users specific color modes (white point, luminance, etc.)
The APS for the Z series printers is the:
HP Advanced Profiling Solution Q6695A
Price: ~$799 (comes included with Z3200ps printers)
Quick Summary: Primarily the APS enables you to make better ICC printer
profiles with the spectrophotometer built into the Designjet Z series of
printers. The APS provides a choice of targets, gray generation, etc. You
can also, with a little work, create ICC profiles for other printers with
the APS. The kit does include a "standard" Eye-One Display 2 which along
with being a display calibration tool also acts as the software activation
dongle.
Hope this helps.

Hello Andrew and Rick,
Concerning the
KZ300AA Advanced Profiling Solution (Calibration Kit)
Is it the same as the APS Kit available for the ZX100 printer series!
(Product number Q6695A-Intl or Q6701A-Asia)
I know the part number is not the same, and I know the price is not the
same
(!), but these two kits have:
- the same name
- are both based on the i1-Display 2
- are both made for products sold under the "Dreamcolor" branding (which
emphasizes color gamut among other things)
If these kits are not the same, is the ZX100 kit compatible with the
Dreamcolor display?
Thank-you,
Danny Pascale

I'm one of the architects of DreamColor here at HP so let me provide a
bit
more information on the display. Since I work mainly in the print side of
the business please take these as my observations and not the official HP
stance.
Calibration & Profiling
- The recommended way to calibrate and profile the display is with the HP
Advanced Profiling Solution (APS) which has an Eye-One Display2 with
filters and software tuned for the display (the SW works on Mac and
Windows). As I mentioned to Bob this software will update the LUTs that
are in the display. You can also create custom "color modes" that you see
in the on-screen display with the APS. More on that later
- A spectral device will create high quality display profiles as well,
but
none of the tools currently talk with the display to update the LUTs so
the calibration will need to be applied somewhere else
- Existing colorimeters, like the Eye-One Display2, may not work as well
as expected given the difference in the colors of the filters when
compared to the display -- Please feel free to provide me your
observations on this point
- Time between calibration is looking to be in the multi-hundreds of
hours
based on the feedback from a few color critical customers; I'd certainly
be interested to hear what you learn
Color Modes
- You can select multiple color modes in the display: Full, Adobe RGB
1998, sRGB, Rec. 709 (HDTV), and a D-Cinema simulation. Selecting one of
these will adjust the white point, color primary intensity, and luminance
to simulate the setting. When you change color modes the operating system
may or may not catch the change and reassign the ICC profiles to tools
like Photoshop correctly so...
- My recommendation on this, unless you are working with tools that are
not ICC managed (video tools mainly) leave the display in its native/full
mode and let the applications manage the colors.
General use
As someone noted the display makes the desktop look rather vivid. Vista
and the Mac OS do not appear to color manage the desktop by default so
the
colors get displayed incorrectly, just the same as viewing sRGB image
mis-tagged as Adobe RGB. If someone here knows how to enable color
management for the desktop, please let me know.
You can enable color management in Firefox by enabling the
gfx.color_management.enabled flag in about:config to at least make it
look
a bit nicer. I'm not sure about Safari, IE or Opera.
