We run an R84F Turbo. CMYKW Ricoh Gen 6 heads. Using Onyx Thrive RIP. Love it. Great quality and speed. We calibrate it ourselves. Send High Resolution files over at 600x1200 dpi and then run on Production speed and quality is high, regular jobs at 600x900 dpi and Production speed. Every now and then a 5x10 bed would come in handy, but we have done 16x20
signs one 4x8 panel at a time. Definitely would buy one again.
