Removing grain from handwritten signature

by

I’ve got a scanned signature that I’m trying to clean up. I was able to use levels to remove some of the grain surrounding the handwriting, but I cannot figure out how to remove the grain from the actual signature. I’m just looking to have all the minute speckles to be joined together as one black seamless line. I feel like this would be pretty easy to do: I have the signature in a separate layer, but going through the filters didn’t get me the result I’m going for. Here’s part of the image I’m working with to give you an idea:

Answer

  • Copy layer
  • Set blend mode of copy to Multiply
  • Filter > Blur > Gaussian Blur set this to 1 pixel.
  • Duplicate blur/multiply layer 3 or 4 more times.

  • Choose Merge Visible from the Layer Panels menu
  • Filter > Other > Maximum – set this to 1 pixel.

enter image description here

  • Image > Adjustments > Levels to tweak things a bit more….

You will probably need to go in with a small brush and draw the hole in the “dot” of the lowercase i. (which I did not do)
