160cm / 190cm Eco-Solvent & Sublimation Roll-to-Roll Printer

3–5 years without lamination, 5–7+ years with UV laminate. Depends on sun exposure, climate, and orientation.  Also this is highly related to the print material you are using.

160cm handles billboards, vehicle wraps, large banners — requires ~4×3m floor space on 220V/2000W.  190cm is for the widest rolls: building wraps, exhibition backdrops — needs ~5×3.5m space on    220V/3000W. If most jobs are under 140cm wide, 160cm is sufficient. 

Yes, But not a goog to do it. We recommend dedicating it to one ink type. First  you must flush the system before switching, Full flushing takes 2–3 hours.

If you will change inks few times, they are ok, but if you change ink frequently, it may clog the print head, differnet inks mix can have the head clog, which is not good.
