Well, this is the dilemma I'm facing. This paper (P III) was made about 4-5 years ago. It came still sealed, along with Super C, same age. The Super C gives very good results, but the P III is very flat and colors are dull no matter what color balance I change. There is no way I can compare it with the current paper since the new paper (P) was re-designed.
The test prints are all clean with white borders. It does not show that the paper is fogged. But the low contrast and dull color make me think the paper has aged (age-fogged). I just do not know if 4-5 year paper can be aged that bad if stored in normal room condition.
I'll probably put aside the paper I can't get it work and spend more time on the "good" papers.
