One of the objectives of the Oracal marketing department in 2011 was employing QR Codes in various collateral. The most recent example of this is the giant QR Code I integrated into my design for a floor graphic panel for a trade show booth. The graphic measures about 26-by-26 inches, and we created a set of four panels, each with its own unique Code. A border of roughly one-half inch was left around the design, which was contour cut and laminated.
For the design, I wanted something that had a technological, futuristic feel. After sketching out the general shape and concept on paper, I began creating from the center to the edges in Photoshop. The center area has circuit board-like shapes (or perhaps Tron-like) to enhance the theme, with the QR Code giving off a bluish glow. The diagonal pattern in the background is actually a replication of our carbon fiber pattern.
As I designed outward, I began layering basic geometric shapes with subtle highlights, shadows, and gradients to give a sense of depth and dimension.
The color palette was kept simple, with the blue and red triangle shapes (which are actually squares that are covered by the circle) offering a splash of color.
I created the QR Code with a handy little FireFox add-on called QRLink Maker. From there, it was a matter of tweaking the Live Trace settings in Illustrator to create a vector QR Code for the large-format prints.
