I tried your suggestion of drying the coated paper thoroughly before printing. I think it helped a little, but the reference palladium prints are still sharper. It has to be the paper. The palladium print I am using as a reference is only 2 1/4 by 2 1/4 inches, so it is not poor contact in the print frame. I have ordered some COT 320 and will see if that solves the problem.
