Flora Rhino 2500 Single-Pass Corrugated Board Printer

Flora Rhino 2500 Single-Pass Corrugated Board Printer

The Rhino 2500 is a single-pass industrial inkjet press for direct digital printing on corrugated board 1.5 – 15 mm thick, on sheets 500 – 2500 mm feed width. It prints CMYK with water-based pigment ink (AQ) that dries naturally, with no curing unit on the line.

Because the heads span the sheet rather than traversing it, output is governed by the resolution chosen. Industrial piezo drop-on-demand heads resolve up to 600 × 1200 dpi. The press runs at 120, 80, 60 and 40 m/min at 600 × 400, 600 × 600, 600 × 800 and 600 × 1200 dpi respectively. Multi-level greyscale printing at 600 × 1200 dpi gives the saturation needed on brown kraft.

The ink system uses dual-negative-pressure recirculation at high flow, which keeps ink moving behind the nozzles instead of standing still between sheets, and ink thermostatting holds drop size steady over a shift. Nozzle cleaning and moistening are automatic. Automatic dedusting is the other mechanism that matters in this application: corrugated board sheds fibre lint, and lint on the nozzle plate is the usual cause of blocked nozzles. Front-edge feed keeps manual handling of the sheet to a minimum, and job changes are made without stopping the line.

Print width is configurable between 645 and 1290 mm as standard, with 1610 mm available as an option, on sheets 400 – 1500 mm long or up to 4000 mm with the optional support. Data reaches the press over optical fibre and the RIP is Photoprint, with the system open to third-party RIP software. Supply is three-phase AC 380 – 400 V at 40 A and 20 kW, with dry compressed air at 6 – 8 bar in a room held at 24 – 28 °C and 50 – 70% relative humidity.

The press suits corrugated packaging plants that need continuous 24/7 output but also take small personalised runs, where changing from one job to the next has to happen without a plate change and without stopping.
