Please excuse me if some of my questions have been asked before. I just
scanned <G> through the more than 1500 messages I've "been meaning
to read" and I haven't found the answers I've been looking for.
My adventure with profiling to date has been less than successful, though
I do see some light at the end of the tunnel which is what keeps me
crawling on. I've invested in a Mc7 monitor calibrator and WiziWYG. The
printers I'm trying to calibrate are all photographic (Pictrography, Fuji
Frontier, KodakLED) and all RGB. My monitor is a Mitsu-1010e
1) What kind of RGB working space is recommended when outputting to
this kind of RGB printer which offers a larger color gamut than CMYK
(which I view using BruceRGB)?
2) Will soft-proofing such a profiled RBG image in Photoshop6 be
affected by the choice of this RGB colorspace and can this be a source
of off colour prints?
3) I've discovered an interesting "profile editing kludge" with WiziWYG. I
can use Photoshop to select and alter the sample color swatches which
were scanned together with the IT8 target print and then run this
"doctored" version through the profiling software. This appears to be a
cheap way to "edit" the profile. If a print comes out too yellow in the
midtones then I just select the color swatches in the scan and add a
similar amount of yellow to the midtones. When passed through the
WiziWYG profiling software the result is a profile with less yellow in the
midtones. Anyone else having any success with this kind of cheap editing?
4) If I want to profile a postscript printer (such as a Xerox color copier),
should Postscript Color Management be turned on or off when printing the
color swatch target?
I've had a busy year of work and teaching (both photography) and now
have some free time to attack the beast anew. Any help with the battle will
be appreciated.
