Measured Paper White Far Off

2009-09-06 by rschoner

Hi,

I was re-doing some profiles using Epson Photo Glossy paper by printing and measuring new targets. Although the profiles seem ok, the paper measures around -100 for the b value. I recalibrated the spectro and then measured the white tile and get 90.6, -0.79, -1.32 which seems ok to me.

Suspecting a driver issue I downloaded your latest software but I get the same results.

I then pulled out a target that I had printed in Sept 08 for the same paper and printer. From the Spyder measurements file  page 3 block H14 had measured 93.9. -2.62, 13.31 and block I14 measured 94.73, 0.93, -5.66.

I remeasured the same target and now get H14 95.84, -2.62, 12.77 and block I14 96.82, 0.85, -105.54.

I really can't figure out what's happening. Any suggestions?

Thanks,
Bob Schoner
