Chapter 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 only contain pure black and pure white—that's true line art. So, how do you get there?

Adding a Threshold Adjustment Layer

You can use the Threshold command to rid the image of all shades of gray, leaving only pure black and pure white. By doing this on an adjustment layer instead of applying Threshold directly to the image, you'll be able to easily make changes after the image is black and white. To achieve an accurate preview when using Threshold, you must view the image at 100% magnification. Double-click the Zoom tool in the Tools palette to quickly zoom to 100%. Create a new Threshold adjustment layer by choosing Layer > New Adjustment Layer > Threshold. Adjust the slider until the lines in the image have the proper thickness and detail appears where it's most important in the image. You can compare the adjustment to the grayscale version of the image by turning the Preview option off and on (to toggle between the grayscale and black-and-white versions of the image).
