RK F 320 / 5 Colour Flexo Rotary Label Printing Machine With IR Lamp Hot Air System

The RK F 320 / 5 Colour is a vertical tower flexographic press: five printing units stacked one above the other, drying between each colour, and die cutting and rewinding at the base. Every unit uses a ceramic anilox roller with an individual motorized anilox system, 360° unit regulation and a dial gauge for registration. A 5 HP AC variable speed main drive runs the line.

It is the mid-point of the RK F 320 series – more capable than the 3 colour machine, lower in cost and height than the 6 colour – and the version RK also configures as a water bottle sticker printing machine.

Five Colour Flexo Printing on a Tower Layout

Five stacked printing units cover process artwork plus a spot colour, or multiple spot colours with varnish, in a 12 ft footprint.

IR Lamp Hot Air Dryers on All Units, One UV With Upgrade Facility

Each unit has an IR lamp based hot air dryer. One UV dryer unit is fitted as standard, and the machine can be upgraded to all UV drying. The individual dryer window system lets the operator see and adjust drying at every colour.

Online Rotary Die Cutting With Waste Matrix Rewinding

One rotary die-cutting unit cuts the label shape inline and rewinds the waste matrix, delivering finished label rolls.

Turn Bar for Back Side Printing

The turn bar flips the web so the machine can print the reverse side in the same pass.

Ultrasonic Web Guide and Load-Cell Tension Control

The unwinding unit carries an imported ultrasonic electronic web guide, a splicing table and paper holder for paper joining, and an imported auto electronic tension controller with load cell feedback. The rewinding unit has the same tension control.

Individual Motorized Anilox and Dial Gauge Registration

Each printing unit has its own motorized anilox roll system, adopts 360° regulation and carries a dial gauge for printing registration.

The label roll (up to 600 mm diameter) is loaded on the unwinding unit, centred by the ultrasonic web guide and held at a steady tension by the load-cell tension controller.

The web climbs the tower through the five printing units. At each unit a ceramic anilox roller meters ink onto the plate, the plate prints the image, and the web passes through that unit's IR hot air dryer – or the UV dryer where fitted – before the next colour. The turn bar flips the web for back side printing when the job needs it.

The web then comes down into the online die-cutting unit, where the label shape is cut and the waste matrix is stripped and rewound. Finished label rolls wind on the rewinding unit (up to 450 mm diameter) under their own tension control. Speed is set on the variable speed drive and registration is trimmed with the dial gauges at each unit.

The price of a 5 colour tower type flexo label printing machine depends on the drying arrangement (one UV or all UV), die cutting, turn bar and options, anilox and cylinder sets. Prices are quoted ex-works Ahmedabad with GST at 18% applicable; engineer transport and stay for installation and training at your site are borne by the customer. Share your label materials, sizes, colour count and monthly volume with RK and the engineering team will recommend a configuration and quote against it.
