Yay for more traditional comic creators!
My comic is drawn on smooth bristol paper and is colored with color pencil, although I do also blend it in with copic markers for larger spaces, and I use white Dr. Ph. Martin's ink for outlines and shines. The process is sketching, inking in panels and bubbles with black 05 ink, then inking the panel contents with 005 blue ink. Coloring, which is the longest process since it involves a lot of layering. Then I reink in black, brown and sometimes green, purple and orange ink.
I usually scan at 600 dpi so I can just size down the pages, and the high dpi scan keeps the images at a pretty good quality.
(Just to warn you if you actually read the comic, the story contains upsetting topics revolving around trauma and mental health. It also is rated R/17+ for nudity and substance abuse, so read at your own discretion.)
