Hi Axel, Robert, ISO 12646 is for display manufacturer to check if their display meets the graphic arts requirements. Here you need to measure uniformity, viewing angle dependency and other things. It is currently out for DIS ballot (hence anyone can access/buy it -> report/comment). ISO 14861 defines the criteria for driving (characterizing) the display and most importantly for simulating a reference printing condition. This is also out for DIS ballot. Since there are limitations in the plausibility of measuring peaky (metameric) stimuli an evaluation based on those readings leaves some room for variation. Hence a visual finetuning is allowed in ISO 14861 to overcome this challenge. ISO 14861 makes no provisions for "stand alone softproofing systems" since there is no agreed upon way to do it (as far as ISOTC130 WG3 [and the experts involved] is concerned). Our certifications (FograCert monitor and Softproofing System) fully reflect this documents, hence you can find more details on our website if you wish. sincerely Andy Kraushaar On Dec 3, 2013, at 9:06 AM, Axel Robert wrote:
Dear all,
I would like to know if I am the only one or not but I have some problems to "certify" my several EIZO CG275W LCD.
As you certainly already know, this display is configured with a built-in calibration sensor which is able to correlate an external sensor, in my case it's a basICColor DISCUS.
All seems to be good in terms of parameters and profile quality (with the Eizo's internal software called ColorNavigator), despite the fact it doesn't pass the Ugra Display Analysis Certification Tool for the white point while it is good in the final internal Eizo's test (a script made in Photoshop).
I tried several settings with different values in term of brightness, luminance and gamma to ensure the display functions properly, even I almost always used the same prefs, that is: Brightness 110 cd/m2 - whitepoint 5800 K - Minimum black point targeted as follow: 110cd/m2 / 288 = 0,38 cd/m2 - Gamma L* according to the ECI RGB V2.
But unfortunately, I always obtain the same extremely bad and very weird result in term of DeltaE whitepoint: 12.1 dE00 or 12.3 dE76… I am totally confused about this results, any suggestions?
Many thanks beforehand!
Axel
