NOVA's rotary tumbler UV printers represent the pinnacle of cylindrical object decoration technology. Engineered specifically for tumbler manufacturing, these systems feature servo-driven rotary tables that ensure precise, stable rotation during printing for consistent 360° coverage. The printers utilize high-performance industrial printheads with variable dot grayscale technology, producing droplet volumes from 3 to 20 picoliters for exceptional detail and smooth color transitions. UV-LED curing systems provide instant ink drying with low heat output, protecting heat-sensitive tumbler coatings while enabling immediate handling. The systems support multiple ink configurations including CMYK, white, and varnish, enabling vibrant graphics on both light and dark substrates. Through-channel ink recirculation prevents nozzle clogging, ensuring reliable operation during extended production runs. Adjustable fixtures accommodate various tumbler diameters and lengths with minimal setup time. The user-friendly interface allows operators to load designs, adjust print parameters, and monitor production from a touchscreen. Optional automated loading and unloading systems further enhance productivity for high-volume operations. With robust construction designed for continuous factory operation, NOVA tumbler printers deliver years of reliable service.
