It's the color curves in the text layer to reduce the contrast. The signature got all errors automatically because it was shot in right conditions with as poor equipment as the paper. It cannot be sharper than the paper photo. Everything would be much easier if there was no need to distort the text. The barrel distortion caused by the lens of the phone camera is also tried to be inserted the text in the same warp session. It got also another warp to even a little follow the bends of the paper. The text layer got perspective warp for that reason. Being above the paper generated an ugly shadow. I couldn't shoot perpendicularly, because I do not have proper tilted lights. The paper on the table is as my phone took it. I tried to compensate by inserting a grey copy which was shifted a little to make an illusion of the debossing shadow. It unfortunately faded from the paper the slight debossing caused by my quite heavy hand an the ballpoint pen.

The separate signature layer needed contrast boost so that the paper became full white to make multiply to work. I shot the signature separately only to see what it causes. The signature layers are, of course, cropped to as small as possible and their edges are faded smoothly to avoid potential difficulties caused by not so exactly white backgrounds.Īs said, ideally only one photo should be shot. I photographed at first the plain paper, wrote the "signature" to an approximately right place and shot a new photo. A little amount of dirt is not fatal, but it's difficult to warp the text layer to follow bends. My paper had some dirt and numerous slight bends. It's ideal if you have the signature already written on it to the right place and the paper is a brand new sheet.
the white background of the signature if you have adjusted it's background to white and let the signature layer have blending mode multiply.Ī piece of white paper was photographed on a table with my phone. They make much easier to match items in different layers.Īs already shown by others, layer blending mode "multiply" can fade full white. Many adjustments such as blur and color curves can be non-destructive "masks".

It's free and it has one substantial advantage over GIMP. This is not much more than you have already got from others, but I suggest you to use Krita.

How can I "write" my signature on a PDF document using GIMP to make it look like I printed, signed with blue ink, and scanned the document - without actually having to print it?
What filter(s) can I use that make this pristine PDF look like it was actually printed, signed, and then scanned? The document itself doesn't look printed and scanned.How do I make the color look more authentic? The color is monochrome, but an actual signature with a blue-ink ballpoint pen should vary in shades as the ink is dragged across the paper.The thickness of the line should probably vary) How can I adjust it to look like it was made by a human hand using a ball-point pen? (eg jitter, smooth stroke, etc. The pen stroke looks like it was made on a computer.But, unfortunately, the country where I live doesn't utilize asymmetric cryptography for signing of documents, so if I want to get anything done I have to actually sign things they give me by hand.Īnyway, using the pen tool in GIMP, I've created a signature on a transparent background. Of course, I'm very aware that non-cryptographic signatures don't provide a trustworthy means of authentication. However, I think it's a grey area for a lot of businesses and governments recently, so I want the signature to look as authentic as possible. Since the COVID-19 pandemic, I've found that many organizations are more accepting of documents "signed" only using picture editing software. For privacy/security reasons, I don't want to take it to a print shop. I don't own a printer, and this document has sensitive data on it that could be used for identity theft. I was sent an important document and, for legal reasons, I was asked to sign it. How can I sign a document only using GIMP such that it looks like it was printed to actual paper, signed with a blue ballpoint pen, and then scanned again.
