The PAL-2000 UV ROLL TO ROLL MACHINE is a wide-format ultraviolet (UV) printer that offers superior printing quality and productivity with roll media. UV Roll to Roll is capable of creating a day-night display that uses ordinary ambient light for daytime display and integrated back-lighting for nighttime display. While the top and bottom layers have the same design, the bottom layer is printed with a different halftone density, making it possible to reproduce the same density during the daytime as at night time. (Three layers.) UV Roll to Roll uses flexible UV Inks; these inks do not crack when the printed media is bent.
