Comparison with the ECI-RGB 2.0 working colour space with regard to the monitor profile

Parameter	Goal	Measured
White point / CCT Kelvin	D50 (5002)	5049
White point XYZ (normalised)	96.42 100.00 82.51	96.29 100.00 83.36
DeltaE from target white point	-	0,73
DeltaE from black body curve*	- (0,07)	0,04
Luminance / cd/m²	140	138,6
Black point / cd/m²	Native	0,21
Contrast / x:1	Native	660
Gradation / average	L*	L*

* CCT context

Apart from the hue losses through calibration, the results are convincing. The grey axis is also very neutral and the respective required gradation is achieved. Because of the high level of coverage for sRGB and AdobeRGB and the linear behaviour of the model, deviations in the colour values are at a low level. The CMM naturally considers the monitor profile created during profiling.

The higher deviations in primary and secondary colours in ECI-RGB are due to the lower colour space coverage. Here, the advantages of the colour management are especially clear here: the undercoverages do not make themselves noticeable on the tertiary colours measured because they lie within the monitor colour space.

UGRA test (UDACT)

Finally, we calibrated the DELL U2410 to the UGRA recommendations (5800K, gamma 1,8 and luminance 140 cd/m² where possible with on-board means) in order to determine its suitability for digital pre-printing processes / soft proofing. However, the certification can of course be achieved with other parameters. If the monitor has no gamma regulator, the range of hues is generally reduced too much through the calibration to pass the test with the parameters indicated. For hardware calibrated screens, we must unfortunately also carry our a software calibration at the moment, since we do not yet have a standalone version available. We limit the black value manually to 0,3 cd/m² in order to minimise weaknesses of the EyeOne Pro.

The detailed UGRA UDACT report for the software calibration can be downloaded as a PDF file.
