A lot has been written about the supposed superiority of the K3 ultrachrome printers (4800/9800/7800) as opposed to the previous generation (4000/7600/9600). There seems to be general agreement that there is no significant difference when printing onto matte media. This makes sense as the matte black ink is the same between the two generations of printers and none of the other supposed advantages are likely to impact here.

For economy reasons -- and the fact I don't (or didn't) print on art papers nearly as often as coated -- I went with a (relatively cheap) 7600 for my Mk output when I got the 7800 for Pk. To be sure, the Pk output difference between the two printers is significant. However in Mk output the real difference I see in the two machines is shadow detail. Not surprisingly, the new machines are better. But IMO you need to compare the prints side-by-side to see it and it is pretty subtle -- present, but subtle. I'd call it smoother shadow transitions.
Re print speed, I have a different take than above: With Mk, I print primarily on the thicker 308 gm Hanemuhle Photo Rag and 300 gm Epson Ultra Smooth Fine Art. For both of these papers I found it beneficial to add in a 1/2 second dry time delay to avoid some very slight roller marks in the deepest blacks, along with a wider platen gap. This added dry-down time in turn slows down total print speed. My unproven assumption is that I'd need the same thing on my 7800-Mk which would in turn slow down print times to a comparable level on it.
Regardless, if money was not a concern I think the best solution would be two of the new printers -- and if/when I start printing more Mk I will probably bite the bullet and move that direction.
Anyone upgrading to the new Canon and have a used 78/9800 they want to sell me?
