Creating brushes in the newly released Autodesk Sketchbook Pro 6 ($30 at the Mac App Store) is pretty easy, but getting the right brush to use for inking has always been somewhat tricky. In this blog post, I’ll show you how to create a custom brush in Sketchbook Pro 6, and provide you with the brush settings I use for my own inking workflow. As with any customization, your mileage may vary…

Here are the steps to create a new brush in Sketchbook Pro 6. First click on the expanded brush palette (see 1 in the figure below). Next, select the Pencil tool. Finally, click the radial menu on the right (see 2 in the figure below) and choose New Brush. You’ll be prompted to create a new brush based on the brush you currently have selected.

Here are the two inking brushes I use within Sketchbook Pro. Both are based off of the Pencil tool.
The first brush yields a clean line with no randomization settings applied.

The second brush that I use has both Opacity and Space randomizations applied.

If you’re struggling to find a good brush to ink with using Sketchbook Pro, give these settings a try.
