PNG, TIFF, JPEG, GIF, XAML, SVG, EPSYou can create a QR code in various formats, but that can be a good and a bad thing – considering scaling of pixel data can become an issue. In fact, if there is one definitive science in QR codes it is readability – if your QR code reader can’t read your QR – well then – it ain’t workin’. Pretty simple! I suggest trying a few readers to verify accuracy and readability. Personally, EPS is always nice to have (even if it is a backup) and/or in addition to a jpg, png or other. Vector = scalability.
When creating a QR code in a pixel based format (other than eps) be certain you have generated your QR code at the size you need. Keep in mind, the concern here, is that if at any time (now) or in the future, your QR code is re-sized and re-used, quality degradation occurs, and readability could be compromised.EPS is scalable without this issue.
QR code generators create a series of pixels based on the url. And the more complicated the URL, the more complex the QR graphic appears. Shortening the url with Bit.ly, TinyURL or similar will simplify the design.
Showing a QR code in a proper size is a must, too small just can’t be read… but also be certain there is ample clear/white space around the code, or it will be difficult, if not impossible to scan.
Creative QR codes were inevitable. Since their inception, QR codes look and feel like a bar code and with that designers were inspired to make them more interesting. Considerations are in the mix of this dialogue
I recently read an article about how we as users and consumers are becoming ever more demanding of the use of our time and with that in mind, QRs will need to deliver some added value to the experience. Simply directly the user to a static web site will not be enough. Be Qreative – sorry – had to.
