Save Time and Money by Testing Your QR Code

Thermographed QR Code

QR code accuracy is extremely important. Inaccuracies could mean a re-print or worse — an unhappy customer. This is why you AND your customer should test your QR codes multiple times, using multiple scanning devices, before the project is finally printed. Here’s a checklist of what to test for in your next QR code campaign.


To ensure accuracy, first make sure the QR code is large enough. The recommended minimum size is 1”x1”, however depending on the density of information you could go as small as ½”x ½”.


You are not limited to black on white by an means. Printing your code in dark ink on a light background will have the best results. The key is having enough contrast for the scanner to read the code. Reversing out the code with a light color on a dark background will have varied results across code readers.


Many print processes, finishes or stocks have a natural reflective quality to them. Using shiny foil on metallic plastic may result in reflections that will cause scanning problems. Examples of this are metallic foil on a glass coat stock or a dark color QR Code on a dark color vellum stock. Thermography also has a reflective attribute that could make scanning hard in certain lighting or at certain angles.


The last part of accuracy checking is the information. You must make sure that everything stored in your QR code (including phone numbers, web addresses, social addresses, etc.) are all absolutely correct. If something is off, you’ll be facing hours of frustration and/or it will affect your bottom line.
