The World's Fastest Cut-Sheet, Color, Injket Printer.
At a glance:

Delphax engaged Design 1st to design, engineer and prototype dozens of internal modules for their a ultra-high-speed 70,400 jet printer that fires up to 700 million drops of ink per second. A new method for wetting paper and a 360 degrees paper guide turn around was devised, designed and tested. Paper path mechanisms for high speed feeding, printing, drying and cutting were developed for Delphax.
