How to authenticate a wet signature.
I have 3 `copies` of a document.
1 is original (ball point) and 2 are copies (laser printer) They all look similar, so does anyone know of a way to differentiate the `wet signature` from the copies. I have tried a UV light but doesnt show a difference. Without causing any destruction as they are legal documents. |

An original ink line should be pretty continuous. A printed one made up of dots, etc. Yes, you should be able to see the toner dots. Look on the white paper a short distance from the black lines of the signature and you'll almost certainly see the occasional toner dot on the copy. |

Without causing any destruction as they are legal documents. teh original will be indented +1, If it really was a ball point try taking a 'brass rubbing' Not sure about that. What TNP might mean is to use a soft pencil sharpened to provide a contact on the "cone" rather than the tip, if you see what I mean, and rub this cone *very gently indeed* over the back side of the signature location (in the way that an artist would shade in an area). Personally, I would start by looking at the back side illuminated from a shallow angle. You might also dribble some laser printer toner on the back, well away from the signature, then tilt the page to allow some to flow down across the signature location. I think this is the technique used to reveal writing on a notepad when the top sheet is missing. |

I`ll give that a try weather permitting :-) What happened was the 2 copies and the original were all mistakenly stamped as authenticated copies despite 1 being an original when they should only have stamped the 2 copies. One way that might well work is look at the reverse side of each piece of paper lit from the side at an oblique angle. The one which was physically signed with a biro should have a slight change in paper height where the nib has squashed the paper fibres. Unless like in classic spy movies they used a sheet of glass to lean on. Failing that and only slightly destructive a solvent like meths or white spirit will dissolve biro ink but not affect the laser copies. A sort of variant on the old spirit duplicator printing method. https://en.wikipedia.org/wiki/Spirit_duplicator My suggestion for a way to find the original is therefore wet a small area of blank white paper with meths - let it soak in until there is no surface wetness. Then press the solvent infused paper against each signature. When you get the real one it will pick up some ink. Try not to smudge it you need to put the paper down and lift it up again without dragging sideways. You may want to practice carefully on a sacrificial test piece first. If you can guess correctly which are the copies by other means you can confirm it by using this solvent test. Laser toner is thermoplastic. Do not under any circumstances apply solvent directly to the biro signature or it may be seriously degraded. -- Regards, Martin Brown |

Once you take a digital photo of all items the differences may be less obvious. A straight scanned copy is not likely to have JPEG compression artifacts. I would look at the documents under a magnifying glass at places where two lines cross such as in the "e".

Update: They finally accepted the `original` despite the fact it was mistakenly stamped as a `copy` What had apparently happened was when first submitted and explanation given it went to their `back office` and a second person read `copy` and rejected it. When submitted for a second time we gave a letter of explanation attached and they were quite happy with that and passed the documents. Thanks all for your input as it did help to reinforce what I thought was the original document. |

But the original will show one set of dots, and the two copies will show original + copying dots, assuming the original dots copied. Even if the original dots didn't get copied, you will have a pair with matching dots and a different document, which is the original. Owain |

Many official documents in the UK insist on black ink and if you go over the line of the signature box it is invalid, eg Passport form Last national survey. I always thought that was because early copiers and scanners couldn't see blue ink. Now that all such scanners have been superseded, it would make sense to allow blue. I have to sign off other people's drawings and documents at work and the standard is that the signature must be in black, but I have worked in other places where the standard is blue - specifically so that the original can be identified amongst black and white copies, pdfs, etc. SteveW |

That is by far the easiest non-destructive test. A 10x loupe easily sees the printer forensic yellow dots in good light. They are all but invisible under a 3x loupe without using blue light. I have had the documents passed now, however, regarding the yellow dots I tested this with blue light and a 10x loupe and none had them. This printed documents from 3 seperate sources. Having said that my copies are on an old laser B&W only Other copy done at PO and most likely B&W only printer And the other was from the sheriffs office possibly just B&W printer also. I suspect the yellow dots only applies to colour laser printers. |
