Important Notes on Whiteness Measurements

We calculate CIE whiteness and tint as described in “Whiteness Assessment: A Primer Concepts, Determination and Control of Perceived Whiteness.” This document, which also serves as a comprehensive primer on whiteness, was provided by Dr. Claudio Puebla of Axiphos GmbH, and is available for download from the Axiphos GmbH site.

As of May 2014, we aligned our GretagMacbeth Coloreye 7000A to a traceable whiteness standard measured at NRC Canada. The UV content of out instrument was slightly low, and was increased to match the traceable standard. Therefore as a result of this recalibration our measured whiteness values are higher than previously reported. Our FTS formulations have not changed; if you want to purchase new standards that match your existing FTS standards, use the same part numbers.
