the brochure contains page after page of gamut info for the new inkset - for the 'clueless' (i.e. me) - in plain english - how does that compare with the K3 Vivid Magenta inkset?

Ultrachrome HDR is bigger than the 78/9880 Ultrachrome K3.

was hoping for something a little more enlightening re: comment

example - Comparison on Epson Premium Glossy Photo Paper 250  on page 29 of the brochure shows only a minimal extension of the gamut vs. the K3VM of the 4880 et.al.
other papers show more.

looking for some 'real world' interpretation of the gamut charts re: what the new inkset might mean re: images. (for example - one comment suggested the new inkset might only be of use in 'non-realistic' color situations).

That's at L* 50...you gotta look at all 4 of those comparisons to see the scope of the larger gamut. These pages are merely "slices" and they didn't go further then 50...but if one looks at a 3D projection of the gamut differences, I suspect you'll see a substantial increase in the total volume of color (as hinted by the L* 80, 70 & 60 plots).

Canon & HP should take note. This white paper, with its gamut comparisons, is what photographers and fine print producers want to see.

wow - quite a gamut boost, plus many other developments, all of which begs the questions: who in their right mind is going to buy a 7880/9880?
and why would anyone spend $12,000 on an 11880, when they're going to get small, medium and large prints (like 60x44") with better color from a 9900?

Epson need to upgrade the 11880 to a 11900, and drop the other two altogether, then have a nice simple 3 machine 7900, 9900, 11900 lineup (not counting the solvent printers)

Thanks for the link, very interesting indeed.

Substantial increase with the Orange on the LM+Yellow mixes and with the Green on the LC+Yellow mixes. The lighter slices of the gamut shape. On the dark side Epson probably didn't find it necessary to show the little increase there. At least the diminishing returns going from the 80 to 50 plots suggest that.

Let's not forget that gamut plots are only an indication of the boundaries , not of the appearance of that colour.

I think you'll find the colours of the pure ink tanks far superior in the colour builds on the x900 models over the existing in gamut colour when you are in zones that use the new primaries with more build than the composites in the VM, or K3 inks.
How good are the colour maps, has to be seen on specific prints. It's not like the 7880 cannot print well, but you will have improvements in unexpected areas that you will find in certain images, or artwork, even being inside the gamut of the VM inks.
