Each print is first drawn by hand and edited afterwards in Photoshop to make small adjustments getting all of the details to my liking and adding color.
I mostly use brush pens for the
lettering. I prefer Kuretake's "Fudebiyori" brushes in most situations. They're cheap and
small but the ink lasts a good amount of time, the brush tip doesn't fray
very easily and is nice and firm. Though, depending on the design, I may
use other tools like a regular pencil or Tombow's Dual Brush Pen. You can buy
most popular pens from Jet Pens
After sketching for a basic feel of how I want the composition/stroke
quality etc., I take a shot at drawing the "final" piece which usually
ends up taking anywhere from 10 to 30+ sheets of paper, trying to get
the composition and each of the letters just right.
Once I come up with one that I'm satisfied with, I scan it and bring it into photoshop where I separate the text from the background, bring out the texture in the ink, make adjustments to letters or composition and then work on coloring.
Then I prep the files to be printed, send them to my large-format printer and cut them out very carefully with an X-Acto knife.
