The K8 Series UV Printer is a family of industrial large format printers and wide format printers built for high-speed roll-to-roll production on the widest standard media rolls in the industry. The KB-500 UV offers a massive 4980mm print width, while the KB-320 UV provides a 3200mm width — both equipped with 12 industrial printheads (3x4 arrangement) in either Seiko or Ricoh Gen 5 configurations. This UV printer machine handles jumbo media rolls end to end — no turning, no seaming, no wasted time. It is the best UV printer for operations that need to match high production targets and budget, offering unparalleled quality as digital printing equipment.
As roll-to-roll UV printers, the K8 Series supports CMYK, White, and Varnish inks across vinyl, canvas, wallpaper, film, and flexible PVC. Its direct-to-media workflow — print and UV-cure instantly — is far simpler and more profitable than the screen preparation and registration required by a flex printing machine used for outdoor banners and vinyl stickers. For commercial printers, a print on demand business, or a sign factory that needs ultra-wide or 3.2-metre width for full-roll production, the K8 Series represents the pinnacle of large format printers. Whether you are doing poster printing on canvas, large poster printing on soft signage, or high-volume sticker printing, this digital inkjet printer delivers the width and speed that separate serious industrial operations from smaller shops.
Up to 4980mm Roll Width — No Seaming, No Turning
The KB-500 UV delivers 4980mm and the KB-320 UV delivers 3200mm — both handling jumbo rolls without seaming or turning. For commercial printers doing large format printing, this means full-width uv printing from start to finish — the best UV printer for high-volume banner printing and large poster printing production.
While a UV flatbed printer or uv dtf printer excels at small-format custom printing, the K8 Series dominates the roll-to-roll large format printing space. With 12 Seiko or Ricoh Gen5 heads and CMYK + White + Varnish capability, it serves as a powerful printer for vinyl, a high-speed sticker printing workhorse, and a production backbone for print on demand businesses — all from a single digital inkjet printer.
Key Advantages of K8 Series UV Printer
4 Models, 2 Widths: Choose KB-500 UV at 4980mm for the widest jumbo rolls, or KB-320 UV at 3200mm for standard wide-format production. Both available in Seiko or Ricoh Gen5 configurations — the same proven large format printer platform, different widths.
12 Printheads: Seiko or Ricoh Gen5: Configured with 12 Pcs (3x4) industrial printheads. Choose Seiko for ultra-durable high-volume output, or Ricoh Gen 5 for exceptional photographic quality. Both options make this the best UV printer for industrial use.
CMYK + White + Varnish Ink System: Beyond standard CMYK, this UV printer machine supports White ink for under-printing on transparent media and Varnish for tactile, high-end finishes. This elevates uv printing far beyond standard digital printing equipment.
Instant UV Curing — No Drying Time: UV LED lamps cure the ink instantly as it hits the media. This digital inkjet printer workflow allows immediate rolling, cutting, and shipping, making it far faster than the solvent inks used in a flex printing machine.
Multi-Speed Production Modes: With High Speed, Standard, and High Quality printing modes, the K8 adapts to any job. For a print on demand business, you can run high-speed banner printing during the day and switch to high-quality mode for premium canvas prints at night.
Versatile Media Compatibility: Prints flawlessly on vinyl stickers, PVC flex, canvas, wallpaper, and PET film. For businesses seeking a printer for vinyl and flexible signage, this wide format printer handles the biggest jobs your customers send.
