| Hi.
|
| Your C.M. settings seem Ok. Have you ticked use Black Point, and set for
| Relative Colourimetric.
|
| But there can be differences between what you can see on screen, and what
| prints. Have you set up View > Proof for the 1290 / Premium Glossy
Profile.
|
| There can be quite a difference, especially in density of blacks, between
| what you see on screen normally, and what shows when viewing the Soft
Proof
| using the Printer Profile.
|
| This sort of error can also sometimes be due to being Out of Gamut. What
| looks black on screen may actually be, or have bits, which are a very dark
| colour. That Out of Gamut colour can be changed by PS to a colour which
| although In Gamut, is different from what you expect.
|
| Again your "Proof" view should help to show this up.
|
| With my system I tended to get Greens in shadow areas of "Black" hair,
but
| practice with Curves, and getting the histogram End Points correct, seems
to
| have solved the problem.
|
| It was much more of a problem with scans from 35mm negs, than it has been
| with Digital Camera Files. (Perhaps iffy processing or bleach fixing).
|
| I assume, of course, that your Monitor is accurate.
|
| I have no idea about the "banding", unless it might be some sort of
| reflection within the camera or lens.

Yes black point ticked, tried proof settings for range of output e.g. RGB,
windows monitor all looks normal. When I use Epson Glossy the proof is
predominently green but I have read that the proof facility is not intended
for emulating rgb inkjet output.

I think you are on the right track when you mentioned the levels and
droppers. I have located my original jpg and printed it without any level
changes or other adjustments and it printed fine.

I'm thinking that I need to read the manual more to learn about using level
adjustments.
