Change in ISO 3664 suggests no UV cut measurements
Change in ISO 3664 suggests no UV cut measurements
Based on the recent change to the ISO 3664 standard for color viewing (2000 --> 2009) I believe that you will want to include UV in your measurements.
The new ISO standard (3664:2009) carries forward all of the primary targets and tolerances for specifications of the lighting environment used for critical color comparisons with one big exception. The new standard calls for a much closer match to the UV portion of the CIE D50 spectrum. Prior to this standard, no viewing systems in general use had enough UV energy to meet this new requirement (MIuv <1.5).
GTI has reformulated our lamp phosphors in order to meet this new specification and the result is more UV energy falling on the image than before. Other manufacturers (Waldmann, Sylvania, etc.) have developed new lamps to meet this spec.
What this means is that you will be seeing more of the effect of OBA's and other UV reactive elements in your viewing booth as the new standard proliferates.
As Gordan says, if its is in the image (eg OBA's), you are better of being able to see it than not. The overall goal is to improve the correlation between the visual appearance of an image and the predicted appearance based on measurements.
