Greetings,
Thank you Mr. Myers for your interesting and thorough explanation (which I have not included in this post because of its
length). It lead me to do some more research after which we changed our Data Color to D50 2 degrees and set it to
specular excluded.
I then measured PMS 186 in our 2006 Pantone formula guide in 5 different places using both the i1 and the Data Color. I
averaged the 5 readings for each and then compared them. Their difference is 2.8 dE.
I was hoping to see them closer as I am sure none of our customers have a Data Color spectro and we already have
customers that claim our color is not correct because our numbers do not match theirs.
Is the fact that the Data Color uses an integrated sphere and the i1 uses a "something else" for measuring geometry mean
that the numbers will never be close?
