The SC-545EX requires no modifications to print with the white ink. However, you can't just pop some new cartridges into an existing SC-545EX. The printer must be brand new, and other inks can't have been used previously.
The print engine is a SolJet PRO II SC-545EX. Basically, this translates to an eco-solvent printer capable of printing on both coated and uncoated media.
The "C" portion of the nomenclature denotes the printer's vinyl-cutting capabilities. The versatile printer can act as a digital printer, vinyl cutter or a contour cutter that can produce such things as decals.
The SC-545EX can handle media widths up to 54 in. You'll need some space for this machine. The dimensions are 106.26 in. wide x 29.25 in. deep x 51.9 in. high, with an uncrated weight of 338 lbs. Like all Roland SolJets, this one is built solidly.
