: How to correct scanned colors in Photoshop? I have scanned a pen and ink drawing and I'm trying get rid of the variations in ink color. The black ink appears as black and different shades

@Angie364

The easiest way, I think, is to fiddle with the contrast and/or levels a bit (both under the Image menu item). If that doesn't get you the desired result, using the bucket tool might also help to get solid colors.

In this particular case, it is fairly easy to make things better. Since the colors are fairly far apart from each other it is easy to isolate them and make changes to even them out. If this were a photo (for example) this method would not work.


apply a "smart blur" to the image to smooth out the color fields
choose "selective color" (under image > adjust) and then add yellow to "yellows (drop down item", blue and yellow to "greens (drop down item)", and magenta to "magenta drop down item"
adjust the saturation by lower saturation slightly and raising lightness slightly to bring the colors back in line with the original scan.
make a new blank layer on top
use "select > color range", pick the black, slide the "fuzziness" to max
with the selection enabled, flood fill on the new layer with black, deselect
make new "select > color range" selection using black and about 60 or so fuzziness
with selection enabled, apply a layer mask to the top layer (this knocks out some of the greys)


This takes longer to type than to do.



(NOTE: In the future, you might look into a photo stand and use a digital camera, photo lights, and a polarizing filter to cut glare.)
