By the time I do my pencils, I’ve already figured out most of the drawing; a combination of an initial pencil thumbnail and digital color sketch which I’ll also use as a guide when I paint. I take that final digital comp and print it out lightly in pink on toothy paper, then use red pencil as a first pass and then a 2B lead for the final drawing. Later, when I scan, I can remove the pink lines. I print the digitally colorized pencils on arches hot press 300 lb watercolor paper on my Epson P800, the inks of which won’t bleed when I apply the paint. A long process, but it works for me!
