I receieved a sample of Photo Rag Pearl printed on the Z3100 (and with custom profile) from a subscriber to my digital imaging research program. It was one of several papers that were submitted to me, printed with my standard test target on a Z3100. All prints save the photo rag pearl were excellent. The Gloss enhancer on the Photo rag pearl seemed almost totally incompatible, leaving a mottled appearance in the deep shadows and the Lmin value was about 16, astonishingly high for a PK paper. Again, all other submitted samples were excellent, so I"m just wondering. Could it have been a bad paper batch, or have any others experienced this issue?
