Aside from that, the inkset, being different, I think, is the culprit.
Even for profiling. I was under the impression I could profile a
stick of gum/printer/inkset combination if it was wide enough (just joking).
The K2 inkset has been widely used on the previous generation large
format (10500 etc.), so apart from the introduction of Red and Blue,
it's difficult to see why anything should be much different. It's
possible it is the Red and Blue, depending on how sophisticated
Epsons separation tables are.
Help me here, Graeme, and anyone else. The poor image shows up, on
screen, when the custom profile is used. And, the image prints the way
it looks on the monitor. (Diamond Pro 2060u) So, the profile is
screwy. I just remembered this. It has been a while since I have
worked with this client's original art.
Depends what you mean by "on screen". I've only tried two custom
profiles, one for Epson Gloss stock, and the other for some
Matt color copier paper I happen to have (for cheap and quick prints).
In both cases I was after "pretty pictures", so I'm
using perceptual intent - indeed, using "relative colorimetric" on
the matt stock gives terrible results, since it's black
level is very poor.
The gloss stock result turned out as you'd expect - photographic.
The Matt result looks pretty good for what it is - a low dynamic range
media. The preview the epson drivers present are the RGB printer
colorspace interpreted as display RGB, so for the Matt stock, the
previews look terrible, but the print is as good as can be expected.
I haven't seen anything strange (bar the mystery of how Photoshop
5.5 chooses an intent when it is managing printer color conversion.)
I haven't noticed any strange color shifts.
The version of Photoshop I have access to, doesn't seem to
have the ability to preview the actual printer output on the
screen. If I generate previews manually, they look like what
you'd expect, ie. for the Matt, very washed out (because the black
is very light), just like the actual prints, with the hues etc. looking
right.
