Re: filmscanners: which space?

If I'm not mistaken Bruce Fraser participates in the Epson Inkjets mailing

Inkjet printers of course print in CMYK but they insist on RGB input and
then perform the conversion themselves.  So we correct in RGB or CMYK or
LAB, whatever fits the bill, but then send to the printer in RGB.

| Hi, Paul--
| Although I've read the manual and "Real World Adobe Photoshop," my monitor
| will not/does not adjust to the Adobe color spaces--or else I'm not
| dedicated enough to follow it out the window, as it were. Since I record
| CD and don't do printouts regularly, sRGB works fine--until I *want* a
| printout, of course.

| no CMYK repro interest)
| I might be misinterpreting here, but I think that outputting to inkjets,
| any printing medium, *is* CMYK. RGB and/or the various color spaces are
| translated and then given to the printer according to the ink colors and
| abilities available, in that machine's color space--I think. This is what
| confuses me--CMYK is meant for commercial printing, which is Adobe's
| suit, and the various color spaces are meant for device-coordination as it
| were (at least, as I read it). But the inks available are still Cyan,
| Magenta, Yellow, and Black (K, since some would mistake it for "blue" and
| some 6-color presses, B *is* blue, and V is varnish). A few processes are
| only CMY, assuming that the three colors will make black, which in Real
| Life, they don't--any more than poster-paints can be mixed to produce a
| reliable brown.
| What I'm wondering is "Why isn't CMYK adjustment more usable for prints
| any RGB color-space?" given that it has to be translated by an algorithm
| be applied. The guys at Adobe try to explain, but the guys over at Corel
| make the CMYK stuff look better on the screen. OTOH, making what's on the
| screen look like what's on the *print* (or vice versa) is all that's
| important at the end of the day.
| I wish that Bruce Fraser would come in here and comment, because I think
| knows the answer. Pretty sharp guy, IMO.
| Best regards--LRA
