Paul,

It’s a bit strange that you don’t get much different reads on M1 than on M0 (M2 I don’t think apply here). There seems to be quite considerable amount of OBA in the paper.

Have you had the chance to personally use or work with this Epson Proofing Standard 240 paper? It is anything but fluorescent. In fact, in my experience, according to shining a 360nm UV lamp at it directly and comparing with other so-called "high-end" OBA-free substrates, side by side, like GMG and ORIS, it does not glow much, if at all. CIE b* < -2.00 are considered "pretty neutral" if you ask me. I don't work for Epson and they're not giving me any paper free, btw. I'm super critical when the time comes to choosing a proofing paper. I know, from experience, how the presence of OB in the paper will haunt me thereafter. / Roger
