Summary This paper describes research into three different but interrelated technologies that can add value to commodity printing substrates by taking advantage of developments in synthetic chemistry, materials science and plasma physics. These investigations have been conducted in a Cooperative Research Centre (CRC) in Australia, called CRC Smartprint. Research into ink receptive coatings based on pigments possessing a positive surface charge has led to coatings that display improved resolution and colour saturation compared with silica based formulations. Although silica exhibits a high level of liquid absorption, it has relatively poor affinity for dye molecules contained in ink-jet ink. The second development involves the use of plasma enhanced chemical vapour deposition at atmospheric pressure to change surface functionality with particular emphasis on absorptive and printing properties. Thirdly, the development of a prototype labelling system based on the application of electrochromic conductive polymer to a flexible substrate that responds to electrical stimuli is discussed. Taken together, these three developments illustrate how both impact and non-impact printing technologies can be judiciously used to apply not only improved visual imagery to paper and paperboard, but also have the potential to enable printing of micro-electronic circuitry directly onto packaging materials, or onto labels that will enable a wide range of improved tracking, security and marketing functions to be incorporated cost-effectively into packaged goods in future.
