REVIEW: Eizo Foris FS2332-BK Part 7

Profile accuracy

In calibrated state, we first check profile accuracy. Doing so, we stay within the limits of the monitor profile created as part of the calibration to sRGB recommendation regarding white point and gradation. After calibrating and profiling, a profile test is performed using the same software to compare the actual status of the monitor with the transformations that result from the monitor profile. The reference values are derived accordingly from the monitor profile.

The profile validation proves that the Eizo FS2332 is able to keep the values that are set in the course of the calibration and profiling constant. As the graphs show, the deviations are very low.

The software calibration and subsequent profiling is based on the parameters listed below (brightness: if available with standard tools). The quotation marks are to make clear that a targeted colour space emulation under no circumstances is intended in the course of the calibration, but simply ensure the specifications listed in parentheses and the highest possible linearity and neutrality. The "colour fastness" is only achieved in combination with colour management software and the monitor characteristics captured in the profile.

In particular, the white point is not a fixed size here, but ideally is dependent on constant ambient or matching conditions. Though the gradation is linked fix to the respective working space, correct reproduction according to the source colour space and its parameters is guaranteed by transformations of the colour management, even if the gradation (if stated correctly in the monitor profile) of the monitor is different.

Provided the screen has a powerful electronic (LUT > 8 bits), it is purposeful to choose the gradation that is designated for its preferred working space, if this is possible with available tools.

"sRGB" (Brightness: 140 cd/m², Gamma: sRGB, White point: D65):
Brightness 49%, contrast 50%, gamma 2.2, Black 50, Red 97, Green 100, Blue 96.

Reproduction of the RGB correction curve of the graphics card after "sRGB" software calibration with iColor. The closer the three coloured lines lie to the 45 ° axis, the fewer colours must be discarded for correct calibration by the graphics card and the more intact colour gradients remain.

To give a first impression of the actual deviations in colour management software, we create suitable test patterns in Adobe Photoshop, which are measured with the respective profile of the working colour space (sRGB, AdobeRGB, ECI-RGB 2.0). Adobe (ACE) is used as CMM. Because of the relatively colorimetric rendering intent, colour compressions caused by the CMM fail to appear.

The very good result after profiling according to sRGB requirement shows the potential the Eizo FS2332 has. The DeltaE deviations of colour values are at a minimum now, even the grey axis is improving a little. White point and gamma correspond almost exactly to the specifications. Due to the low black point of 0.15 cd/m², the contrast increases to 933:1.

UGRA test

Finally, we calibrate the Eizo FS2332 to the recommendations of the UGRA (5800K, gamma 1.8, brightness, if attainable with available tools: 140 cd/m²) in order to determine its suitability for digital printing processes / soft proofing. Of course, the certification can be achieved with other parameters, too. If the monitor does not provide gamma control, output levels generally are limited too much due to the calibration to pass the test with the parameters given. Manually, we limit the black level to 0.3 cd/m² in order to minimize the weaknesses of the EyeOne Pro.

As we have already noticed, a 10-bit LUT does not guarantee for the passing of the UGRA test. But since the Eizo FS2332 provides a viable gamma adjustment and premium electronics, the monitor obtains the certification without problems. While at least 95 per cent must be achieved to pass the UGRA test, most monitors fail due to a too low output levels. The Eizo FS2332 obtains 96.6 per cent.

With these settings, we calibrate to the recommendations of the UGRA: Brightness 49%, contrast 50%, gamma 1.8, Black 50, Red 100, Green 100, Blue 90.
