Book, Publishing and Commercial Print Production

The Kirin660CHD has been developed for high-volume colour production environments requiring offset-like quality on coated and uncoated substrates.

Typical applications include:

• colour books and educational publications,
• textbooks,
• children’s books,
• art books and photo books,
• magazines and periodicals,
• catalogues and brochures,
• corporate reports,
• marketing and promotional materials,
• manuals and technical documentation,
• short-run commercial printing,
• personalised Variable Data Printing (VDP) applications.

With a maximum print width of 648 mm and a web width of up to 660 mm, the system supports efficient multi-up production layouts, including 2-up and 3-up configurations depending on the final product format. This enables economical production while maintaining high print quality and efficient substrate utilisation.

The system supports a wide range of substrates, including gloss-coated papers, matte-coated papers, offset papers, digital printing papers, book papers, lightweight papers, cardboard, and other commercial printing stocks.

High-Speed CMYK Duplex Printing

The Kirin660CHD combines Single Pass inkjet technology with industrial-grade piezoelectric printheads to deliver high-quality duplex colour printing at production speeds of up to 200 m/min.

Designed for demanding publishing and commercial print environments, the system provides excellent image sharpness, smooth tonal transitions, and consistent colour reproduction across long production runs.

Dedicated print bars for each colour channel support accurate colour control, stable registration, and reliable image quality throughout the production process.

Advanced front-to-back registration control ensures precise alignment between both sides of the printed product, supporting applications that require accurate duplex reproduction and consistent page-to-page quality.

Optional Mark Reading functionality enables accurate overprinting on pre-printed materials and previously prepared webs, providing additional flexibility for complex production workflows.

Triple-Phase Drying System for Coated Papers

One of the key technologies behind the Kirin660CHD is its Triple-Phase Drying System, developed specifically for high-speed inkjet printing on coated papers.

The drying process combines three independent stages:

• Instant Drying System,
• Roller Drying System,
• Hot Air Drying System.

This multi-stage approach improves drying efficiency, controls ink penetration, enhances colour vibrancy, and reduces the risk of substrate deformation during production.

Designed for use with standard gloss-coated and matte-coated papers, the system helps eliminate the need for specialised inkjet-treated media while maintaining excellent image quality and production reliability.

The result is stable, high-speed colour printing on coated substrates with consistent quality across long production runs.

High-Density Low-Moisture Pigment Inks

The Kirin660CHD employs proprietary water-based High-Density Low-Moisture pigment inks developed specifically for high-speed colour printing on coated and uncoated substrates.

The ink formulation minimises moisture penetration into the paper while maintaining high optical density, excellent colour saturation, and consistent image quality.

The combination of active ink recirculation and small droplet technology reduces ink consumption, minimises purging requirements, and contributes to higher overall production efficiency.

Key benefits include:

• high optical density,
• faster drying performance,
• reduced substrate deformation,
• lower energy consumption,
• improved colour consistency,
• enhanced durability and fade resistance,
• broad substrate compatibility.

The system supports gloss-coated, matte-coated, offset, digital, book, and other commercial printing papers.

Industrial Printhead Technology

The Kirin660CHD utilises industrial ceramic piezoelectric printheads with active ink recirculation, engineered for reliable operation in demanding production environments.

Continuous ink circulation reduces the risk of nozzle clogging, minimises maintenance requirements, and supports stable long-run production. The system also improves thermal stability within the printhead assembly, helping maintain consistent print quality during extended production runs.

Printhead specifications include:

• Operating frequency up to 80 kHz
• 5,116 nozzles
• Variable droplet size of 2–4 pl

Combined with 1200 × 1200 dpi resolution, these features deliver sharp text, smooth gradients, and high-detail image reproduction suitable for colour publishing and commercial print applications.

Roll-to-Sheet Production with Inline Finishing

The production line integrates unwinding, web guiding, Single Pass inkjet printing, drying, and optional inline finishing within a single workflow.

Depending on production requirements, the system can operate in Roll-to-Roll or Roll-to-Sheet configurations. The optional finishing module performs inline longitudinal and cross cutting, as well as automatic sheet stacking, enabling highly automated production from paper roll to finished sheet stacks or separated book sections.

The Offset Book-Division function automatically separates book blocks during production, reducing manual postpress handling and improving overall workflow efficiency.

Inline cutting speeds of up to 120 m/min support continuous high-volume production while maintaining accurate finishing performance.

Stable Web Handling and Registration Control

The Kirin660CHD incorporates a multi-zone web tension control system, advanced Web Guide technology, and precision servo drives to ensure stable substrate transport at high operating speeds.

The web path has been optimised for duplex production, supporting accurate front-to-back registration while minimising the risk of web instability. High-precision guide rollers and a reinforced machine frame contribute to repeatable print quality during long production runs.

The combination of web guiding, tension management, and registration control ensures reliable operation across a broad range of substrates and production conditions.

Professional Workflow and Variable Data Printing

The Kirin660CHD is equipped with a professional RIP and workflow platform developed for industrial digital printing environments.

The system supports efficient PDF processing, Variable Data Printing (VDP), colour management, and high-volume production workflows. Advanced rasterisation and image optimisation functions help maintain consistent colour quality and precise reproduction of text, graphics, and images.

Optional job parameter logging enables colour settings, calibration data, and production parameters to be stored and recalled, supporting repeatability and reducing setup time for repeat jobs.

Together, these workflow tools provide a productive and scalable environment for modern digital book manufacturing, publishing, and commercial print production.
