*Correct. By "Epson glossy paper selected as the media" I mean the printer
was told it was loaded with Epson glossy paper while it actually was printing
to Pictorico OHP.

Use the info window. As each pixel is pointed to, the %K and RGB values
are displayed. (snip)<
*Like duhhh. I've been staring at the info window for days...right in front
of me...thanks for opening my eyes.

would print in Pt/Pd. Would you send me two identical small step
gradients with several steps of known printed tone including 100% and
0%? (snip)<
*Will do...may take a few days to get to.
But, check out the big jump in density between 95-100% compared to the rest
of the scale. I was surprised by it.
