Current brushes of choice
From Kyle T Webster’s Megapack:
- For line art, Kyle’s Inkbox - Badass Brush at 35 pixels.
- For colouring, Kyle’s Inkbox - Roughest Ink No Alias at 40 pixels.
The brush sizes assume a document with a resolution of 300 DPI.
Converting pencil artwork to non-repro blue
- Open up the scanned pencil artwork in Photoshop and use a Levels adjustment layer to improve the line quality and whites.
- Clean up the artwork with white on a separate layer, if necessary.
- 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.
Cleaning up line art
- Clean up the scanned line art in Photoshop with adjustment layers:
- Remove any non-repro blue underdrawings with a Hue/Saturation adjustment layer. After choosing the Cyans colour range in the Properties panel, set the saturation to minimimum and lightness to maximum.
- Use Curves and/or Levels adjustment layers to improve the line quality and whites, and remove any remaining underdrawings.
- For inked line art, use a Threshold adjustment layer to convert the line art to black-and-white bitmap.
- At the bottom of the Channels palette, click on Load channel as selection to create a selection of the white areas of the image.
- Invert the selection.
- Create a fill layer; the selection will be applied to the fill layer’s mask. Alternatively, use the Paint Bucket tool to fill the selection on a new layer.
- Deselect the selection.
- Delete or hide the scanned artwork and adjustment layers.
Image filesize reduction techniques
- Use ExifTool and jpegtran to reduce JPEG image filesizes:
jpegtran -optimize -progressive [IMAGE] > [OUTPUT] && exiftool -all= --icc_profile:all [OUTPUT].
