Do I have this right? Thanks.
All i1Display PRO's (OEM / Retail / or Branded OEM like C6's) are calibrated from X-Rite (no other company can change the default factory calibration, so any NIST certification is just confirming that the meter is fine from the factory only, nothing more than a pass/fail test, since the meters are low cost and X-Rite is not providing any proof that they are certified, just the unit to unit variations performance is controlled, its not so large deviations like Spyder's).

X-Rite provide the EDR to software developers. When you select EDR file of a display tech, its combined with the factory calibration of the meter data and then its calculated the correction.

EDR files are X-Rite meters feature (ColorMunki Display/i1Display PRO), can't be used from for other brands of meters.

When you are using EDR, you expect that the meter is accurate, and because such colorimeters are low cost devices, there unit-per-unit variations (unit per unit variations are ignored, not counted when you are using EDR corrections.)

Because Tom have seen (and all of us also) that the results are better when you are using meter four color matrix correction tables using a reference spectro (so you correct the readings totally for a specific display type) he is equipping the i1Display III (called) with software offsets for many display types.

Much appreciated Ted; I'm starting to get the feeling my next investment should be a reference spectro before a TPG!

ChromaPure 3.1.18 Released

ChromaPure 3.1.18 is now available for download from the ChromaPure News site. This release is free for all ChromaPure v3.x users.


This release includes support for a custom white point. NOTE: changing the white point will affect the Reference Color Gamut. In the vast majority of cases this option should be left alone. The application always returns to the default white point with each new calibration session. This release also adds support for the Adobe RGB gamut and a number of other enhancements and bug fixes. See the Release Notes on our News page for details.
