Can anyone give some advice as to which brush size is most suitable for line art-ing comic books? I'll be using Painter for this, and I've chosen a customized pencil variant for this. But I guess the tool doesn't matter, I just need to know the size.
I ask this because having switched to digital media (and with all privileges of zooming in and out) I find it hard to see what size is suitable for line art and keep things consistent. My line art looks too thick, even when drawing with a brush at 0.1px. Is there a way to view the brush size adjuster in mm? Atleast that way I can keep track as to how it might look when printed.
Back in the day when I was a more traditional pen-on-paper guy, I remember how choosing the right pen size (0.01, 0.1, 0.5, 0.7, 0.9 and so on...) was all it took to get the right line widths on an A4 paper.
