How to Capture a Digital Signature

by Martin Cole

It may be that you want to make your emails feel more personal to the recipients. Or perhaps you would like to add authenticity to important documents that you send over the Internet. There are many reasons why you may wish to create your own digital signature, and doing so is not as difficult as it sounds. Simply write down your signature on a piece of paper, scan it in and edit it with Adobe Photoshop. It then will be ready to add to any document.

Sign your name on a piece of paper a few times so that you have a selection of choices for your digital signature. Use a pen that will leave a thick line and write in larger letters than you normally would. This will make the writing clearer when scanned.

Place the paper into a scanner. For a clear signature use a scanner with at least 600 dots per inch (DPI) resolution.

Scan the paper.

Open the scanned document in Adobe Photoshop.

Choose the signature you would like to be your permanent digital signature.

Shrink the image down to the size you would like for your signature.

Straighten the angle of the signature so that it will line up with other writing on a document.

Click on the magic wand in the top corner.

Click "Select," then "Inverse."

Copy the image.

Click on "File," then "New" to open a new document.

Click on the "Transparent" radio button in the options window that appears. Click the "OK" button.

Paste the signature into the new document.

Take out any white inside the letters with the magic wand tool in the top left corner.

Click on "File," then "Export" and finally "PNG Optimizer."

Click on "File" and then "Save." Choose a folder to store the signature and then click "Save."

Open this file and paste the image to any future document that you wish to add your signature to.
