no reason for aqueous inks not to work - as long as you getting inks for piezo heads like on your roland - ie, epson inks and similar, no thermal ink (hp, canon). as for running it in cmyk mode it will have to be done trough your rip - custom ink set or whatever it's called in your case, just turn off lm and lc. you'll have to do your own profiling. just curious - why not buy an aqueous ink cmyk printer? they are generally cheaper than solvent printers, i've seen people converting aqueous into solvent, but not the other way around. ??
