I’m looking for the cause and solution for a system that was all set up and nicely linear, with new problems. Visual symptoms were dumping of values resulting in loss of shadow detail. A chart print out reveals the curve shown in the attachment. My suspicion based on that is that the medium Gray might have been refilled with dark gray ink.
Any thoughts on what you see here would be helpful. This is the cold side of a Pro setup, the warm side seems good to me, as well as it’s measurements.[attachment file=28648]
Thanks for any input,
