ImageMagick is my favorite "go to" for image manipulation and I would start with this example script, if I wanted to add grain: http://www.fmwconcepts.com/imagemagick/filmgrain/index.php http://www.fmwconcepts.com/imagemagick/filmgrain/index.php And yes, ImageMagick can be a rabbit hole of possibilities too. But now I'm tempted to try it … tomorrow.

Occasionally I have to physically sign, scan and email a form. However, I don't have a printer or scanner. I just paste my signature into the PDF then use ImageMagick to add grain and slightly rotate the pages so that it looks printed and scanned. Works every time.

  I just paste my signature into the PDF and send it like that. Occasionally I'll get someone complaining about some vague thing they can't quite articulate (something about it not being a "real signature" or not having been "really filled out"), but when I just insist that "yes that's my real signature" and "what I sent you is the filled form" they always end up accepting it. Usually it's just some clerk or administrator and they have no basis for refusing the document. I just tell them to pass it along and process it, they always end up doing so, and I never have any issues.

    In the US, fax signatures are legally valid and scanned imagery is considered equivalent. A modified PDF is not sufficient.

      Eventually, someone in the US will make bank selling "signature laundering machines" - basically the ImageMagick script on a microcontroller in a tamper-proof enclosure that's plugged as peripheral, with paper trail certifying that the output it produces is equivalent to printing a document and scanning it again, or faxing it, and therefore should be legally considered as equivalent to fax.

      Have there been any court cases where a contract was considered void because the signature was digital? I’m really not sure under what basis one would make that determination. Signatures are mainly symbolic and provide nearly zero guarantees. Sure there’s some extra security you can build around signatures (eg.: docusign), but paper doesn’t really have all of that extra stuff.
