No. Metamerism is caused by the mix of inks that the Epson drivers use to print grays. They use as much colored ink as black and light black. All the colored ink causes metamerism.

Not if you're using the Epson drivers. You need a program that gives you full control over the cyan, magenta, yellow, and black channels. Then you need the 3rd party profile to reduce the CMY used in the grays, and try to make them mostly from black and light black.

Short answer, printing with PhotoShop is like shooting with a point and shoot camera. Auto everything, and little control. (It's no coincidence that PhotoShop and "point and shoot" are both initialed "PS"). QTR, ICM/OCP, ImagePrint, etc. are like using the camera on manual, exposing via the zone system, and paying attention to your darkroom procedures. You don't get a "master print" from the drug store.

But most folks don't seem to see QTR as being quite as difficult as you seem to be finding it. I'm having trouble "debugging" you on the forum. If you want to mail me a print, I might have more insights...

Ciao!
