Hi List
Apologies for a shameless plug....
I've written an application called viewSIGN which compares the colour
accuracy and gamut of a monitor to a CMYK print space.
It works using any CMYK ICC profile and can generate PDF reports and
digitally sign a PDF file and uses ∆E76, or ∆E2000.
visit www.presssign.com/viewsign.php to download. (only supports the
Eye-One display2, and Eye-One Pro - Mac and Windows)
The tests performed are similar to ISO 12647-7, so theres a Max,
average ∆E, grey balance, paper and primary tests.
It's been very interesting to test various monitors and see actually
how each one compares in colour gamut to a printer. Changing the white
point can have a dramatic affect on the colour gamut, just for the
reason that Lab values are measured relative to an illuminant. So you
biggest colour gamut would be at the native whitepoint of your
monitor. Unfortunately, most monitors seem to have a native whitepoint
of 6000-7000K, so if we calibrate the whitepoint to 5000K, we then
have a problem with displaying the correct yellow. Cyan can be a
problem when calibrating to 6500K.
It's also interesting to see how long these monitors actually last.
I've had reports of monitors loosing about 15% of their gamut after 6
months. Not good for a £1200 (€1400) monitor
