I think you're absolutely right!

During the 10 minute transfer, all I could think about was how terrible the "rolling" of the mat was. Fingers were crossed...

By the way, looking back at my first transfer with the kodak magenta, one which I did not post and with which there was no rinse at all after the dying, the dmax is very strong. So!, it seems that the less acid present in the rinse (or none at all) the greater the density. I guess this makes sense if you consider that the acid might heighten the matrices affinity for the dye..??
