If you wonder what DoDxAct stands for you are probably not the first to ask, and understanding what Mark Bale does – the name is ingenious! The abbreviation is short for Drop On Demand (e)Xact – and that is exactly what all this is about. As you know, or will learn in this film, the printheads are only one of the essential components of a functional printer. The controller, the ink, and obviously the substrate needs to be aligned to make a perfect output. Mark Bale focuses on the printhead, where he teaches, consults, and also has a lab where he can test all of the above. Enjoy the film!
