Something very strange is happening to my prints using UT2 on Ilford Heavy Weight SemiMatte paper. The high end densities are just melting away very rapidly. I printed a step wedge this morning about 11 o'clock, I used a hair drier on it for several minutes, and then waited about hour. I measured the exact same wedge five times during the day -- see the times. Also here's a graph of the ink usages -- carbon-only M and LM(m).
