In a joint project for the Swiss cardboard and paper packaging solution provider PAWI Verpackungen AG, Sun Chemical and Esko have successfully implemented seven-color ex-panded color gamut (ECG) printing at PAWI’s facility in Winterthur.
PAWI can now offer customers the option to select ECG printing instead of spot color printing for suitable jobs and take advantage of its significant benefits – a reduced inventory of spot color inks and increased productivity with reduced downtime between jobs (as the seven colors are left in the press), enabling just-in-time production.
Working in a three-way partnership, PAWI engaged Sun Chemical, its ink supplier for more than 20 years, to set up seven-color ECG printing on a recently acquired eight-color offset press by adding orange, green and violet to the standard cyan, magenta, yellow and black, enabling the reproduction of 95% of spot colors.
Sun Chemical achieved this through the deployment of its own ECG solution, SunECG, part of SunColorBox. A component of SunECG is Esko’s color conversion software, Equinox, which identifies the exact percentage of each of the seven colors needed to reproduce the desired spot color.
Instrumental to the success of the ECG printing process are Sun Chemical’s SunPak FSP inks, which are based on renewable, bio-based materials and designed to work on most folding carton-type, sheetfed presses including standard, high-speed and wide-format.
“While seven-color printing has been around for some time, it is only in recent years that it has really become commercially viable, thanks to the improved stability of the presses and inks and the advances in the software, all supplied by our partners of choice, “ said Alexander Honsel, head of strategic projects at PAWI. “We’re now looking forward to roll-ing out the program in stages and to being able to offer our short-run customers the op-tion to produce high-quality packaging products with seven-color ECG printing at a com-petitive cost.”
