Measurement

The DT NGT2 is manufactured with extremely tight tolerances. That is, every DT NGT2 has color patches that are almost identical in color to any other DT NGT2 (such nominal values are published here).

However, when creating and validating color profiles in high-end applications (such as compliance with FADGI 4-star Preservation Grade standards) even very slight variations from one target to the next will matter. In such cases, each target should be individually measured. You can do this yourself (provided you have the equipment, expertise, and time) or you can purchase the DT NGT2 target pre-measured.

The measurements will be made by an expert in metrology, using a bidirectional (45:0) spectrophotometer, reporting spectral reflectance (with measurement-confidence interval) and CIELAB calculated using illuminant D50 and the 1931 2° standard observer. The CIELAB data will be formatted as comma-delimited CSV file. For other illuminant/observer or reporting options or more information about the traceable measurement process please contact us.

Measurements are delivered on a USB stick at the time of purchase. These measurements will also be permanently available via theOpenQualia Label Standard – you can print a label for any DT NGT2 which has been measured using any QR code generator.

Here is an example of the measurement (in OQM format a flavor of, and compatible with, CGATS) for the serial number DT-AR-2020013.

All DT NGT2 targets are labeled on their front with an individualized serial number, so that they can be easily identified now and in the future. Replace the serial number in the link above with yours and if your target was individually measured it the measurements will be directly downloaded.
