As I'm sure most of you know, there is a (relatively) new specification for D50 viewing conditions: ISO 3664:2009 read more at http://www.idealliance.org/specifications/swop/
I was wondering if anyone has actually made the full switch to new lamps and what (if any) issues have arisen?
We have GTI booths & lights and the upshot for us has been that there is significantly more UV content in the light than in the older lamps. Because most of our proofs are on inkjet proofing stocks that have no OBAs, those proofs have an almost identical appearance as the do under the older lamps. However, since most press stocks have a significant amount of OBAs, the difference between proof and press is now more pronounced. I realize that this may be a more "accurate" representation of the difference between proofs and press, but as far as clients are concerned, our proofs are now *less* accurate.
It seems that the de facto standard for high-end inkjet proofing stocks is that they have no OBAs, which makes proof to proof matching easier (my certified GRACoL proof matches your certified GRACoL proof), but makes proof to press matching harder. The new lighting standard just makes this situation more obvious. I was wondering if anyone uses proofing stocks with OBAs specifically to try to match closer press stocks, and if so, how's that working out for ya?
Any advice, stories or comments surrounding these issues would be greatly appreciated!
