Converting Pencil Artwork to Non-Repro Blue in Adobe Photoshop

1. Use a Levels adjustment layer to improve the line quality and whites of your scanned pencil artwork.
2. Clean up the artwork with white on a separate layer, if necessary.
3. Convert the image to grayscale (using the Mode menu found in the Image menu) and then to monotone using 20% cyan as the primary ink. The shade of cyan used might depend on personal preference and printer output.
