SPT Konica 512i 8-Head Negative Pressure Flex Printer – Overview
The SPT Konica 512i 8-head negative-pressure machine is the maximum-output configuration of the NP platform: eight KM512i heads with controlled negative-pressure ink delivery that keeps every nozzle firing through full-speed shifts. It is built for print houses producing thousands of square feet of banners daily – highway hoardings, building wraps and campaign volume.
The SPT-512I-8HNP runs daily production on flex banners, vinyl hoardings, backlit flex displays, one-way vision film, mesh banners, PVC vinyl stickers & vehicle graphics, canvas, reflective media and outdoor advertising cloth. Solvent prints are waterproof and UV-stable for long outdoor life, and the machine’s service ecosystem is supported across India.
