Assumptions:
You are going to use the scan as a ‘signature’ on computer documents. All the documents have a white background.
Your signature is between one and two inches long, half inch tall.
Your best bet is to rescan at a higher DPI.
Depending on your scanner/software, make two scans; Grayscale, Color. This gives you some options for the next steps.
Image/Adjust/Brightness-contrast
Use sliders to make the scan background as white as possible.
Crop the resulting scan as close to the image as possible. This reduces the file size and limits problems with text/graphic overlap.
File Save As: signature.BMP AND signature.JPG
Some applications are picky about graphic file types.
‘Sign’ and print a test document to verify.
Repeat as necessary.

Hello everyone, I have scanned my signature but it is not smooth. Is there any way I can retouch it using either photoshop or illustrator. Thanks for any feedback.
