I need some help with Imageprint Lite. I am printing with an Epson 2400, from a Macintosh, OS 10.5.7. The images are 16 bit TIFFs, 360 ppi, resized and converted from raw to aRGB in Lightroom.
Printing on Epson Premium Glossy paper, or luster-type paper (e.g. Epson Premium Luster, Museo Silver Rag), using photo black ink, the darkest blue shadows show extreme posterization, transitioning from a strange electric blue abruptly to black. Using relative instead of perceptual intent almost cures the problem using glossy paper, but has only a slight effect on luster paper.
ColorByte suggested converting to sRGB, but this has no effect.
Printing directly from Lightroom shows no problem at all, except that I much prefer the IP profiles for the non-Epson papers.
Has anyone else run into this? Can anyone suggest a solution?
Thanks
