Application Spotlight: Printing on Mini Kegs with the Helix® High Throw

The Rise of the Mini Keg

Mini kegs are the ultimate preservation of beer. Unlike growlers, mini kegs maintain carbonation for a fresh sip, prevent oxygen exposure, and dispense beer using CO₂. Perfect for parties, camping, and tailgating, a mini keg is typically only 5 liters, whereas a half-barrel keg is 12 times larger at 15.5 gallons. The jump from a 14-pour keg to 165-pour 12 oz. beers makes these smaller, portable options ideal for smaller-scale activities amongst good company.

With the continued stability and growth of microbreweries, more and more consumers are looking to take quality beer on the go. Instead of selling growlers, many breweries: large and small are now offering mini kegs as a solution for fresh beer in group settings. And where there are mini kegs, there’s demand for decoration.

The Decorating Challenge

As a decorator, have you had to turn away jobs for mini kegs? You’re not alone. Being taller and wider in diameter, mini kegs pose a tricky substrate to decorate.

Mini kegs are primarily constructed from durable, food-grade 304 stainless steel, designed to withstand carbonation pressure while resisting rust and corrosion. Digital UV inkjet printing lends itself particularly well for printing on this type of metal surface, it can enhance and play up the metallic shine of the container for a premium finished look.

One traditional method of decorating mini kegs involves printing on flat sheets of metal before they’re formed into shape. But for those looking for more flexibility and shorter runs, printing on the mini keg after it has been shaped opens a lot of doors, and that’s exactly where the Helix® High Throw comes in.

Introducing the Helix® High Throw for Decorating Mini Kegs

The Helix® High Throw is purpose-built for challenging cylindrical substrates like mini kegs. Designed for 360-degree wrap printing on cylinders and tapers, this machine brings industrial capability to decorators who need versatility and precision, especially on vessels that have a wider diameter.

Print Capabilities

The Helix® High Throw features a full WW+CK+MY+LcLm+VV or WW+CK+MY+VV ink palette with optional primer, delivering vibrant, durable prints at up to 600 x 1800 dpi resolution. White ink support allows for stunning opacity on metallic surfaces, while the varnish channel adds a protective and aesthetic finish. The segmented, software-controlled UV curing unit ensures consistent cure across the full print area, even on complex surface profiles.

Built for Mini Kegs

With a part diameter range of approximately 2.56″ – 7.09″, the Helix® High Throw is well-suited to the dimensions of standard 5-liter mini kegs. Its programmable tooling tilt and automatic height-adjust accommodate the unique shape of these containers, while product profile sensing and high throw support ensure accurate ink placement across the curved surface.

The fully automatic programmable tooling fixture means setup is repeatable and efficient, critical for short-run brewery jobs where changeovers need to be fast.

Software & Production Features

The Helix® High Throw runs on an industrial computer system with recipe storage and Helix® production reporting built in. This means decorators can store job parameters for repeat orders and track output with confidence, keeping production moving and customers happy.
