I'm still making progress in formulating a generic base for carbon printing that will print smoothly on Arches -- as well as other papers. Arches uncoated watercolor paper is the tough one, however. So, it's been my focus. See http://www.paulroark.com/BW-Info/Carbon-7.pdf at 2 for 1600 dpi scans of the 45% test patches of the latest C7 mix compared to Epson K3 LLK and Eboni-6 LM. The smoothness differences are now quite obvious. Paul www.PaulRoark.com
