HP Indigo's technology drives a new era: Nonstop Digital Printing

In the fast-paced digital print industry, HP Indigo leads through continuous technological evolution. As a pioneer in the field, the company consistently addresses core industry needs, empowering customers to capture new growth opportunities with groundbreaking digital presses equipped with intelligent automation.

Indigo LEP, LEP^X and Nonstop Digital Printing

At the core of HP Indigo’s presses lie two proprietary technologies: LEP (Liquid Electrophotography) and the next-generation LEPX. Both provide performance built on quality, versatility, and consistency across a wider range of substrates than most digital technologies allow.

Where inkjet systems - especially water-based and UV - face drying and adhesion constraints, HP Indigo’s ElectroInk is dried before it reaches the substrate, eliminating issues like bleed or distortion. The result: offset-class quality, high color accuracy, and substantial ink efficiency.

This substrate agnosticism isn’t theoretical, it’s engineered into the press architecture. With support for up to 97% of the color gamut and a robust portfolio of specialty inks (including white, silver, invisible, and fade-resistant formulations), HP Indigo enables converters to take on everything from food-safe packaging to premium labels with confidence.

Nonstop Digital label Printing at 120 m/min

LEPX takes that foundation further. Built around six synchronized imaging engines, it prints multiple colors in parallel, a major leap in digital throughput. The result is not just higher speed but analog-like economics paired with digital flexibility, something that was once seen as a contradiction.

This is the breakthrough behind the HP Indigo V12 Digital Press, now printing at 120 m/min - the fastest in the digital label segment. Designed for mid- and long-run production, it brings fast turnarounds, variable data printing, and sustainability benefits to converters who once relied solely on analog.

Early adopters of the Indigo V12 are already hitting productivity milestones, with many ordering second presses and more - a strong signal that HP Indigo’s Nonstop Digital Printing vision is becoming reality.

Scaling Up with Proven Platforms for Labels and Packaging

Like the Indigo V12, the HP Indigo 6K+ , the newest evolution of the market-leading Indigo 6K press, also delivers reliability, automation and versatility. With improved durability, ease of use, and the new SmartControlSystem, it enables label converters to print continuously while managing multiple SKUs and job types with minimal intervention.

For those expanding into flexible packaging, the HP Indigo 200K offers unmatched field-proven performance. Now equipped with an optional add-on slitter, it bridges the gap between label and packaging workflows — supporting converters as they diversify.

With over 400 installations globally, the Indigo 200K is the only digital press in its class that’s demonstrated large-scale viability in flexible packaging.

Intelligent Automation on the Production Floor

HP Indigo’s ecosystem goes beyond the press. With AI-powered tools like AAA 2.0 and PQ Maestro, quality control is now automated and AI-driven. The systems handle tasks like defect detection and print setup, dramatically reducing operator burden.

In partnership with MoviGO, HP Indigo also introduced the industry’s first Autonomous Mobile Robot (AMR) for digital print production, reflecting a broader commitment to efficiency, connectivity, and smart manufacturing.

The digital future is here

From presses like the HP Indigo V12, Indigo 6K+, and Indigo 200K to advanced automation and specialized supplies, HP Indigo is shaping the next era of digital print. The Nonstop Digital Printing journey is no longer just a vision — it’s already underway. And with each innovation, the company is redefining what will evolve next on the production floor.
