Re; 1. ISO-3664:2009 illumination (graxx@videotron.ca) Hello Roger Just to add, if the luminaire uses a glass or plastic cover you have to check if it is effectively UV filtering. Most old and many modern ones are. Below is a GTI reading, no glass which is 3664:2009 compliant. [image: GTI.png] regards Malcolm Mackenzie Colour Engine
Dear Malcolm, A full verification of a light source, as Mr. Claas Bickeböller has said, requires a device like Instrument Systems CAS 140CT-152 (with a range of 200 to 800 nm) which is beyond the reach of the typical printer. The manufacturers have to take care of the ISO 3664:2009 compliancy of the luminaire. Best, Refik -------------------------------------------------------- Refik Telhan, EE B.Sc.

Hello Refik Yes that is true but as with many of the ISO standards I believe we have to make some adjustment for the real world. Roger is using the FD-7, I used a GL SPECTIS 1.0 for the comparison. So good instruments for client side measuring. What is not acceptable and I see it a lot, is the supposed passing of lighting to ISO 3664:2009 using an i1Pro. regards Malcolm On Mon, 17 Jun 2019 at 11:54, Refik Telhan <rtelhan@icloud.com> wrote:

ISO standards reflect a consensus of (mostly) a group of experts (investing time and money) - so there is no need to adapt criteria to the real world (since they struggle hard to find criteria in the given scope) :-) regards Andy Wir stellen den Hintergrund in den Vordergrund.
