The n.jet soldermask by transforms PCB manufacturing through highly automated multi-color inkjet printing. Its smart ink supply system enables rapid switching between red, green, blue, and black solder mask colors with minimal flushing. A second module allows simultaneous legend printing, eliminating separate workflows. This innovation significantly reduces setup time, material waste, and manual effort—ideal for prototyping and small-batch production. It meets top criteria for efficiency, sustainability, and integration. Targeting agile PCB manufacturers, OEMs, and design houses, it offers unmatched flexibility, cost-effectiveness, and responsiveness to color-coded PCB demands in dynamic production environments.
