Key Units of the HP Digital Printing Line:
1. Rewinder
The web is rewound onto reels, which can measure up to 60 inches diameter, for downstream roll-fed processing.
2. Web Extender
After the moisturizer, a festoon system called the web extender allows time for adequate moisture absorption before rewinding the printed material.
3. Moisturizer
The moisturizer replaces any moisture that is lost during the priming, printing, and varnishing drying processes, and helps restore the paper to its original characteristics.
4. Post-Coater
Overprint varnish (OPV) is applied as a flood coat and is dried using an integrated dryer. OPV may protect the print and enhance its visual appearance.
5. Inline Process Control (IPC)
The Inline Process Control System uses high-speed cameras to capture samples of printed output to monitor nozzle health and ensure top inkjet print quality.
6. Dryer
After printing, the paper passes through three high-intensity dryer sections that use a combination of infrared light and forced air to enable the ink to dry on the paper.
7. Print Engine
The curved arch design provides tight control of the paper tension for accurate printing while maintaining a very small printhead-to-paper spacing to ensure clean, sharp text and images.
8. Digital Front End (DFE)
The HP SmartStream Production Elite Print Server is a highly scalable server-based Digital Front End that rasterizes incoming artwork files and delivers data to the press in real time.
9. Pre-Coater
The pre-coater applies HP Priming Agent to the paper as a flood coat before printing. HP’s Priming Agent is an aqueous solution that ensures optimal print quality across a wide range of paper.
10. Winders
With print speeds up to 183m (600ft) per minute on 1.06m (42in) wide paper, the press can print on coated and uncoated papers ranging from 80 to 350 gsm, with a maximum caliper of 18 points.
Efficient and Cost-Effective Printing for Lamination and Folding Carton Applications
Print up to 183 m/min (600 ft/min) to reduce turnaround times, lower minimum order quantities, and optimize inventory—while focusing offset presses on long runs. Support diverse applications with a web width up to 1.06 m (42 in) and a printable frame length up to 2.7 m (108 in), improving flexibility and streamlining downstream processes. Achieve consistent six-color offset quality with HP Thermal Inkjet (TIJ) technology—featuring 1,200 nozzles per inch and 8X nozzle redundancy for crisp text, smooth gradients, and accurate barcodes. Produce vivid graphics on coated, uncoated, and kraft substrates with HP Priming Agent. Use Harris & Bruno’s inline coater for overprint varnish with knockouts, supporting repeat ranges of 30–70". Choose from Aqueous or AQ/UV coating options. Maximize productivity with group job submission, enabling multiple jobs per roll and minimizing waste. The HP PageWide T470S is built for cost-effective short and mid-sized runs—print partial rolls with no make-ready, no plates, no setup waste, and no ink or spot color mixing.
End-to-End Solutions from a Trusted Partner
Unlock maximum digital production flexibility by integrating HP One Package software and trusted partner solutions into your workflow. The HP One Package Preprint Production Module links the press with your existing workflow systems, automating the creation of digital multi-job reels. It adds production marks readable by downstream devices—such as sheeters, laminators, or corrugators—indicating job boundaries. This enables efficient, low-waste processing of multi-job digital reels. One Package also integrates with inspection and reel editing systems to automate their operations, while providing real-time feedback to ERP and logistics systems—delivering a fully connected, end-to-end solution.
