You heard it here first. They are wonderful. In the past, they never
used to be. There are no noticeable color crossovers either. Just
reporting what I'm experiencing.  I'm not having that good luck in
getting great color prints from this very same inkset. Too flat, and
reddish, without large tweaks in photoshop.  Maybe this is a new and
different ink, or maybe it is in some way faulty, but it is my
experience with this set of inks, anyhoo.

It is accurate for this set of inks, anyhow.

Oh no, the ink cost savings make the CIS well worthwhile.

Like I say, this has never happened to me before either. I've always had
green/magenta metamerism with epson inks. But not with THIS inkset.
Epson makes it's inks in many places. Maybe one of them finally got it right.

Yes, no profiling, no curves.

This is on Legion Photo matte paper. Other papers are much warmer and
some have the dreaded crossovers. And the setting is simply on
automatic, 1440 DPI, and generic RGB setting in the final print dialogue
box. Paper matters!	On EAM paper, the prints are definitely brownish. On
eclipse papers, they are green/magenta/light/no good blacks, etc.
Definitely NOT the paper to use with epson dye inks! I now have to
replace the cartridges, and the ink that I will be now using came from
Atlex. We'll see if everything holds up, and I'll report any differences.

Before I actually get another CIS inks system, I want to see the neutral
piezo inks that Jon Cone is releasing soon. I understand MIS is
releasing yet another inkset. This is getting out of hand. Who has time
to test everything that's out there anymore? One thing sure, I won't get
another CIS unless the inks can deliver a very neutral tone, with a
D-max of 185 or better.

I've seen them. They are totally unacceptable to me. Horrid!

I wouldn't.  As I say, this has not happened to me before, and I have
never seen the great black and white tones I'm now getting with the new
1280 and the inkset that came with it.

The small gamuts produced magnificent daylight tones with about 40 blue
and 10 cyan for me. But the metamerism under tungsten lighting was very
magenta. Not acceptable.

I will tolerate brown tones under tungsten light, but not
magenta/green/blue/yellow/red/ etc.
