Hi,
Hi to all
Let me explain this a bit. When we moved to PMS+ we changed paper type so
we had to redo the data base. This has nothing to do with X-rite buying
Pantone. At the same time, X-rite was introducing XRGA and that technology
was applied to the new data set. We measured the first printing across many
replicates and built the new data base. PMS+ colors changed for a number of
reasons, but primarily the paper base was different. It was a conscious
decision to use environmentally approved FSC (forest stewardship Council)
paper.
All current X-rite instruments are XRGA standardized and if they contain
PMS+ data it is from exactly the same source that is distributed to Pantone
Licensees. The data that is shared with most licensees is UV cut
(Measurement mode M2). There are many legacy instruments which are not XRGA
upgraded or do not have the upgraded data base in them. I believe that the
instrument has to be returned for upgrade and recalibration.
The current values in Photoshop CS5 are correct.
