This is the last step of the drawing process - ink over blue. Some people asked how I make these, and the answer is: in Photoshop on a 12" Wacom Cintiq.
I used to work at 72dpi (intentionally) to keep file sizes small and to prevent me from trying to make the comics look too ... professional. Ha! But eventually I caved in and now work at 300dpi on a 2400x3600px image.
For inking, I just use a plain round 30 brush at 100% hardness. I switch to a 19 for finer lines. Other than that, the only tools I use are the eraser (a lot), blue guidelines, and the lasso (to move things around).
Unfortunately, working in a high resolution Photoshop document while running screen capture software gobbles up nearly all 768Mb of RAM on the old ass PC I use for drawing. It ruins the pressure-sensitive line quality, and makes drawing curves or circles pretty much impossible. So if you notice me drawing a shape like 30 times, that's why.
Anyhow, this is about an hour and a half compressed to 6 minutes for easy digestion. Hope it's interesting to watch, and if you have any questions: echols@oneredtwo.com
