Capter 5. Line Art Scanning > Converting to Line Art

Converting to Line Art

When you print an image that contains shades of gray, your printer uses a halftone screen, which prevents your grayscale image from having crisp edges. In order for you to get nice, crisp edges, the image must contain only pure black and pure white—that's true line art. So, how do you get there?

There is no need to apply a Threshold layer if your end result will be used onscreen for the Internet or multimedia, but you might need to enhance the contrast of the image by choosing Image > Adjustments > Levels. Move the upper-left slider until the lines in your image become completely black, and then move the upper-left slider until the background is completely white. If you've done that, then you can stop right here and save your image in the GIF file format.
