I usually use the 140 lb/300 gsm full sheets. Using Eboni MK and QTR, the highest dmax I've seen is 1.63 with an Epson 1400. However, each batch is different, and that dmax is not the norm. Usually I see about 1.56.

Wow, 640gms? How does that compare to 1/4" plywood?
What weight Arches do you normally use? I have been using 300gsm with the R3000 & 3800 as it compares to the PA325 but the dmax has been poor - fighting to reach 1.4. This evening I remixed the inks in hopes of getting it right..
