The creation of QR Codes started with the aim of creating a symbol that could encode Japan’s Kana and Kanji as well as improve the 20-character limit of a traditional barcode. Headed by Masahiro Hara of DENSO WAVE and his development team, they have successfully created QR Codes in 1994 and started contacting various companies to support the implementation of the project.
Since then, the influence of QR codes has expanded and it was adopted early in the Japanese auto industry and later on products, brochures, posters, billboards and in many other promotional activities and materials.
The creation of QR codes has revolutionized the way business and organization communicates and operates, here are some of the things that you need to consider.
Identify the distance when scanning the QR code
During the first stages of development of the QR code, Hara’s team started within the 10-20 centimeter distance from the symbol to the scanning device. Depending on your need, you should be able to identify the distance needed for your symbol to work out. Is it for ecommerce, products, retail, etc? It is important that any scanning device will be able to read clearly your symbol.
Consider where your symbol will be printed
Before creating QR code, think of the possible platform to where you are going to print the symbol. If your market will have to use a mobile phone or other external scanner, make sure that you print it in areas where mobile phones will not have difficulty to detect the symbol.
Consider the size of the symbol
Make sure that code is readable even if it is in its smallest size. The recommended size for a minimum 0.5 mm dimension will be based on consumer grade mobile device testing ISO/IEC 16480. Future standards may include applications with smaller X-dimensions.
For larger dimensions, there are no yet definitive recommendations due to the variations in distance from the mobile device’s camera to the code. However, if you want to know the distance from which the symbol will be read, calculate the minimum dimension for the symbol through the formula Xmm = Distm * 4.
Rule of thumb: It is always good to use a dimension a bit larger than the minimum.
Lastly, you also have to consider the angle of the symbol at a point relative to the mobile device should be no greater than 20 degrees to increase the likelihood of reading the symbol.
Consider the print quality
The print quality of the symbols for printed materials, posters, billboards and for printed 2D symbols should be compliant with the ISO/IEC 15415.
Identify the pros and cons of inserting logo into your symbol
Inserting your company logo or any special mark into your symbol is a unique way of personalizing your code. However, this can reduce the ability of any device to read your symbol.
