Integration of 2D codes in Paper and Board Packaging – Reproduction and Readability

Abstract

KCPK is running an initiative called SSK, or Smart and Slim Supply Chains, dealing with bio-based packaging and innovations for making overall supply chains smarter and slimmer. SSK initiative covers the full trajectory from production, through distribution to the consumer. SSK focuses towards four different types of supply chains and several types of printed intelligence, with 2D codes included.2D codes are a kind of 2D matrix symbology which, when compared to 1D or barcodes, have specific advantages that enable novel and extended opportunities of use. In 2D codes, data is encoded in both the height and width of the symbol, so large amount of information can be encoded in smaller footprint. 2D codes can be read in any direction. Some 2D codes provide readability of (up to 30%) obscured and/or damaged symbols, as well. Most known 2D codes are QR and Datamatrix, and other open and proprietary types exist. Other than for logistics and part marking, 2D codes are nowadays also more used in print to web, marketing and added-value applications. The aim of this paper is to investigate the application of 2D codes in bio-based packaging. Solid board is used as a specific example of such packaging. Direct printing of 2D codes, using digital printing techniques, is studied in terms of influence of material and process characteristics on achieved print quality reproduction and readability.
