Daco DF350SR Semi-Rotary Die Cutter / Varnishing

DF350SR is a small compact converting and finishing machine for digital and inkjet. With quick and easy setup, a short web path make it the ideal machine for digital label finishing. Features include flood coat or spot UV varnishing, laminating and cold foiling.

Daco DF350SR semi-rotary die cutter for the finishing of digitally printed labels


The Daco DF350SR is a compact, versatile semi-rotary die cutter / converting line for digital labels, semi-rotary for short runs and full rotary for high-speed longer runs. The machine is available for flexographic printing applications or the converting of media from pre-printed digital, inkjet, and flexo printing presses.

The Daco DF350SR has seen a significant upgrade to both its mechanics and software recently and now has an increased maximum production speed of 80m/min (262 ft/minute).  This coupled with the ability to remove the 22” magnetic die cylinder and replace it with our standard full rotary dies allows the die-cutting of labels to a maximum speed of 175m/min (575 ft/minute) in register.

Easily apply spot or flood coat UV varnishes, the DF350SR can also be configured with an optional laminating station to give ultimate flexibility for digital finishing applications.

The flexographic print/coating station utilises the latest in servo drive technology and with software written by Daco Solutions allows for quick and easy setup. With the environment and paper costs in mind, the print to die register is accomplished with the use of minimal substrate.

The platform also allows for the fitting an inkjet module, and we can fit both mono and CMYK systems allowing for labels to be printed and finished in one pass.

The flexibility of the DF350SR platform enables a converting line to be configured for most digital finishing applications:-

Full servo mode:

Standard flood coating

Die-cut in register to a pre-printed web

Optional: Spot varnish

With the servo, print/coating station turned off:-

Die-cut to register – Die cut to register pre-print webs

Slitting and rewinding

Plain label production – full or semi-rotary
