Gethray C4 Flex Printing Machine – Overview
The Gethray C4 Flex Printing Machine is the machine Indian flex printing units are built around. Konica Minolta 512i heads on a 3.2-metre chassis give you the classic formula – tough outdoor-durable solvent prints at speeds that keep the take-up roll busy all day. The C4 scales with your business: start with 4 heads and step up to 8 heads for up to 2400 sq ft/hr of banner output. BYHX electronics with UltraPrint, MainTop or PhotoPrint RIP support mean any operator in the industry already knows how to run it.
The Gethray C4 runs all day on flex banners, vinyl hoardings, self-adhesive vinyl, one-way vision film, mesh, backlit flex, coated banner, PVC and PP media, canvas and fabric backdrops. Solvent and eco-solvent prints are waterproof and UV-resistant for long outdoor life, and the machine’s service ecosystem is supported across India.
