Tired of printheads clogging and ruining your book runs? The UB-SP440 SERIES Digital POD Inkjet Printer​ is here to fix that. This isn't just another digital press; it's the first to feature Dual Channel Printing Technology, designed specifically to eliminate the "white wire" (broken needle) effect that plagues monochrome printing. 🛠️

Why Print Shops Are Switching:

🧠 No More White Lines:​ The proprietary Dual Channel tech isn't just a gimmick. It significantly boosts nozzle lifespan and eliminates the streaks that kill productivity. Fewer clogs mean more uptime.

⚡ Speed Meets Quality:​ Choose your weapon. The UB-SP440 series offers multiple models (Pro440C, K-HD, D-HD) to match your workflow. Hit speeds up to 120 m/min​ in monochrome mode, or opt for high-definition color at 90 m/min, all with a tight duplex accuracy of ±0.2 mm.

📄 True POD Workhorse:​ With a max printing width of 436 mm​ and support for rolls up to 1270 mm​ in diameter, it handles standard offset and digital papers (50-120 gsm) with ease. The integrated RIP and imposition software turn PDFs into finished books in one seamless flow.

Key Specs That Matter:

Max Speed:​ 45 m/min (Std Color) | 90 m/min (HD Color) | 120 m/min (HD Mono/Dual)

Resolution:​ 600 dpi (Std) | 800 dpi (Production) | 1200 dpi (Fine)

Ink System:​ Water-based Pigment Ink (CMYK or Mono)

Footprint:​ ~12.4m (L) for full HD series with drying

If you're running a book printing, manual, or commercial POD operation and are sick of the downtime caused by finicky printheads, the UB-SP440 is your solution. 👉 Click to request a live demo video and see the "no white line" difference for yourself.
