Man ,If you have the space and coin that S80600 is a niiice printer. Huge color gamut with Lc, Lm, Orange and red inks. Fine detail with 4.2 picoliter drops. With the new piezo heads and setup maintenance looks easier that prev. generations. it comes with Onyx RIP. but like any solvent, they like to run.
If you are doing MX graphics , and money is no object - skip the Combo Epson is offering and buy a summa T series. It will perf and kiss cut better and easier than the FC8600. I have owned the FC7000 and FC8600 and was never happy with Contour Cutting accuracy TBH. The Summas have a wider - softer I think strip for perf cutting, and little to no complaints about OPOS system. Or better yet, Flatbed FC graphtec for 18 mil plus.
Hope you have the work lined up - thats alot of money.
