Jim is correct that the rev. D is also using the new LED
illumination too.
I don't believe this is correct.
Just to makes things more interesting the HP z-series printers measure at
20nm increments while the rev A-C (not sure about rev D) measure in 10nm
increments.
Rev D is exactly the same. The main change is the faster sampling rate.
Also interesting to note GretagMacbeth devices always measured
in 10nm increments while X-Rite choose 20nm increments for their legacy
devices.
Not correct. Most X-Rite devices (ie. DTP41 etc.) return measurements
at 10nm spacing.
And if you are following all of this then you might be interested
to know the sampling of HP z-series is 400-700nm unlike the i1 which is
380-730nm.
X-Rite's instruments traditionally returned 400-700 in 10nm increments,
while the Spectrolino and Eye-One Pro do 380-730 in 10nm increments.
The underlying resolution of the Eye-One Pro is about 3.3nm spacing.
