Having spent a good deal of time answering questions about QR codes lately, I figured the easiest thing to do for everyone was just write an article. And so I did. It went live very early this morning at evolt.org. Go check it out: Making and Using QR Codes.
If you aren't familiar with QR codes, they are those pixelated-looking collections of black and white squares that have been popping up more and more in recent weeks and months, even though they have existed for years. The QR (Quick Response) code was first developed in 1994 in Japan to track vehicle parts but has since grown to become a handy way to encode all sorts of data, most notably web site addresses for use in traditional media campaigns.
In the article I outline the general process of using QR codes in your own projects by providing suggestions on encoding web page addresses, how to build the QR code itself, and basic pre-press tips. I also push some other ideas, such as embedding on your printed web pages or embroidering into your headgear.
