This plugin produces good results quickly provided that the document is homogenously lighted and the paper itself is also of homogenous quality. You'll have to experiment with your documents to find the right settings.įrom this point, you can duplicate the image, flatten the duplicate, and use your regular Photoshop retouching tools to clean up the remainder. A scanned document typically has a histogram with a large lump toward the right (the paper) and a smaller lump toward the left (text). Use a Levels adjustment layer to increase the contrast. I was able to darken the text only a little. Notice that the yellows slider is far to the right, lightening the yellowish background. Use the Targeted Adjustment Tool ("Scrubby") in the adjustment layer panel to lighten the background (scrub to the right) and darken the text (scrub to the left) as much as you can. Convert to grayscale using a Black and White adjustment layer.The details will be different depending on the document (this has somewhat higher contrast than your sample, for example) but the broad outline will be the same. Here's part of a fairly typical old document scan: If you have control over the scanning, or can get them rescanned, increase the contrast setting in the scan and set the black point at the darkest bit of text you can find.
