In a talk last year Les explained that most commercial printer profiles are pretty useless, because modern USB spectrometers don't have enough power to use polarizing filters and thus read through the glare on darker color values.
Color calibration of screens and printers is tricky and you need a professional screen like an EIZO to see 99% of Adobe RGB color space. No screen can see more than Adobe RGB but if the image is in ProPhoto or another large color space, good printers can print colors you can't see on a screen. Most screens only see sRGB which is the color space of the cheapest possible CRT monitor from the 1980s. It also happens to be the default color space for Adobe Creative Suite, Photoshop etc.! Most scanners seem to only scan in sRGB too.Les's notes on his web page are useful for all this sort of stuff.

I may eventually try a professional printer to make a series of limited edition signed prints but for now home printing on art papers produces a nice enough job. I don't have large prints and this way I don't need to keep inventory. Someone wants a print, I print it. And I charge what I think is a reasonable amount, well more than $10 for an 8x10!Thanks, Lore
