Quick to Dry and Tough to Scratch

Combined with the EJ-640’s integrated tri-heater system, EJ INK dries fast. Even in high-speed modes it offers quick and even drying results that enhance image brightness and quality. Due to the speed of drying, EJ INK offers greater scratch and chemical resistance with durability up to three-years outdoors without lamination.

Same Eco-Solvent Ink Quality with Added Configurations

Although EJ INK is an economical ink, it doesn’t compromise on quality. Its quick drying formula enhances image saturation and offers the same ink brightness and image sharpness you’ve come to expect from Roland. With dual-CMYK plus Light Cyan, Light Magenta and Light Black ink options on the EJ-640, users can create graphics with finer details, smoother gradations and more neutral grays.
