Hello Roger!
Actually XF has two kind of ink limiting tools - total ink limit and ink
limit per channel. And you can lay as much ink as you want.
First of all, find a suitable TIC on "Step1" by yourself, don't rely on XF
enginge, it's play safe. When you aim a mouse on a patch, you will see
correspondent Lab values.
Go from top to bottom from left to right and find a sutable value for you.
Usually it'll be 50-100% greater than XF offers.
The second thing - don't try to increase Light inks in Solids because you
are decreasing color saturation of 100% patch! I'm using usually 1% Light in
Solids.
On step 2 go into Advanced settings. XF also play very safe here. Adjust
Black channel to decrease L in shadows. Also you can adjust CMY to increase
gammut.
I'm getting L aroun 8 on proofing gloss and semigloss papers with XF on
Epson 4000.
But it's almost impossible to get such L values with Ultrachrome Photo inks
on some semimatt proofing papers (like Best 9150, it looks like matt coated
paper, maybe your Fuji paper is a kind of such papers). In my opinon it's
not a problem of the RIP, it's a paper-ink interaction problem. In such
cases you can try Ultrachrom Matt black ink. It's possible to decrease Lmin
up to 9-10 and to improve shadows.
