Mac 101: Capture your signature using OS X Lion's Preview app

OS X Lion has made signing PDFs easier than ever before. It's been possible to scan in your handwritten signature and sign documents in earlier versions of Mac OS X, but it was a complex process and one most people probably never trifled with. More often than not, I found it easier to simply print out the document, sign it the normal way, and scan the whole document back into Preview using my flatbed scanner.

Lion's version of Preview comes with a built-in signature scanner that makes signing documents far simpler. In the Annotations toolbar you now have an option to create a signature from your Mac's built-in iSight camera. All you need to do is use black ink to sign a piece of white paper, align your signature toward the camera using the onscreen guides, and take a snapshot of the signature. (I haven't used my real signature here, obviously.)

Preview can store multiple signatures, so if you need to both sign and initial documents, you're able to do so easily using Preview's annotation functions. It's a great feature, and one that ensures my printer will be gathering even more dust than it already has.

[Just to be clear, this process only applies a graphical representation of your signature; it does not cryptographically 'sign' the PDF document to ensure that it has remained unmodified. Adobe's Acrobat application can sign PDFs with both a graphic and a digital signature; NitroPDF also has this feature, as does the DocQ web service. The DocuSign web service provides 'electronic signatures,' which are not exactly the same thing either. –Ed.]

One step closer to a truly paperless office

if you get autograph (free: http://www.macupdate.com/app/mac/32996/autograph) you can write your signature on a multitouch trackpad with your finger, which imo is easier

I just paid $22.87 for an iPad2-64GB and my girlfriend loves her Panasonic Lumix GF 1 Camera that we got for $38.76 there arriving tomorrow by UPS. I will never pay such expensive retail prices in stores again. Especially when I also sold a 40 inch LED TV to my boss for $675 which only cost me $62.81 to buy. Here is the website we use to get it all from, BidsGet.com

Now that we've captured it in Preview, is there a way to insert it into Pages documents or import it into other programs?

Yes -- save it as a PDF or PNG, and you can insert it as a graphic.

Great addition to Preview, love it!

Just for fun, line your face up to the blue line…. creates a remarkable BW sketch of your dear mug. =)

Truly a paperless office! Now excuse me whilst I write my signature onto a piece of paper so I can scan it in.

I've been doing this for years using a program called PDFpen, which also lets you add text to documents. For example, you can use it to fill out scanned PDF forms. With PDFpen, you can even modify text that's already there (but not scanned text).

But this looks pretty quick and easy for adding signatures. Combined with Preview's annotation features, I might not need PDFpen very often any more. Nice Job(s), Apple.

I'm surprised how paperless I've become in my work and home life. My ink jet printer at home complains that the ink cartridges are past their expiration date long before it complains of low ink. I have a laser printer, and I'm dreading the day when I have to replace the expensive toner cartridges, but who knows when that will be. It's been years, and still I'm using the anemic starter cartridges that came with it.

Interesting that Lion would say "iSight" and not "Facetime".

Actually, not in the Annotations toolbar: not sure what version you're using, but I found it (eventually) in the Preferences. Then I have to hit Accept for the camera to actually turn on. Finally, it works.

Deleted that one, repeated the same process, and then I see the note "To add a Signature to a PDF, use the Signature pop-up menu in the Annotations toolbar."

No one else had this same sequence of events?

The best way to do this is Preview->Preferences->Signatures which works with most compatible webcams. As a Mac Pro user, I don't have an iSight which I think will work with the Annotations option.

I don't think you'll see the annotations toolbar unless you actually have a document open
