SPEED. Lots of it. This machine just flies! With a 64" max print width and speeds up to 1250sf/hr, runs on Roland EcoSol Max 2 inks. The Roland XF 640 is a CMYKx2 print-only device which houses mirrored CMYK print heads to generate screaming fast output without banding or loss of quality. The printer will lay down 7 different ink drop sizes eliminating the need for a six color configuration. Other great features are that it will hold production size rolls of media - rolls which weigh up to 110 pounds - so you can load up and go!
