It's again about "prints are dark" issue :-)
What we have - different Windows opration system (XP, Vista, Vista 64), Lightroom 2.5, Photoshop CS4, Epson 3800. For Epson last drivers and last firmware installed.
ColorBase used for every PC.
Profiles - from Epson and custom made.
Monitors are calibrated at 100cd/m.
Color management by application at any case.
Problem - if I print from Lightroom with relative colorimetric intent, prints looks darker than displayed at monitors.
If I print with perceptual intent, print are very close to monitor.
If I print from Photoshop with relative colorimetric intent and Black Point Compensation ON, prints are close to monitor.
If Black Point Compensation OFF, prints are dark, very close to Lightroom printout.
Lightroom has no Black Point Compensation at Windows OS?
