Efficient Characterisation of Printing Systems for the Packaging Industry
Abstract:To print accurate colours, every printing system needs to be characterised. Nowadays, this characterisation is performed by printing and measuring a colour target and creating an ICC profile. Every time the substrate or the ink changes, this procedure has to be repeated. In frequently changing environments, like the packaging industry, the standard colour characterisation procedure is too demanding in resources to be of any practical use.
In this work, we present a novel technique that characterises the printing system without reprinting a colour target at each substrate or ink change. It requires the printing of a target only once per printer system and can handle an ink or a substrate change with an off-line spectral measurement of the new ink or substrate. This results in a substantial progress in terms of resource allocation and costs.
To achieve our goal, we developed a new physical model of a printer. In addition, we needed an algorithm for modifying an existing ICC profile based on this model.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
