I should just be finishing this, but I guess experimenting with comic inking isn’t the worst form of procrastination. A lot of comic book artists who still work with ink do their pages on 11"x17" paper. Among the advantages: little imperfections disappear when shrunk down to print size, and the larger the scale, the easier it is to manipulate a brush or brush pen.
So anyway, working on a sheet of 8.5"x11" paper made for a panel around 3" wide, and even my tiniest brush pen seemed too thick unless I gave it a featherlight (and shaky) touch. So to see what it would be like to ink in the larger format, I printed this panel at about 5" wide. Turns out that’s a great size for rendering lines similar to the digital ones I’d settled on, using my Zebra fine pen.
