Mondi’s six-colour digital printing range for corrugated board now includes water-based white inks for brown materials, facilitating high-contrast designs for primary and secondary packaging.
Using a white underprint is expected to help logos, motifs, and colours stand out on brown corrugated board. These high-contrast print images are set to boost a pack’s visibility at the point of sale and strengthen a customer’s brand identity.
Halftone printing can also be used for smooth gradients, differentiated shading, and chamfers that create three-dimensional image effects.
Apparently, all the inks are water-based, with Swiss Quality Testing Services (SQTS) testing and approving their food safety for primary packaging.
Digital print is described by Mondi as ‘one of the most flexible and sustainable printing processes available today’. The company cites high production speeds and high-quality, multicolour print images on both white and brown outer layers, as well as open flutes.
Compared to flexographic or offset alternatives, digital printing can reportedly apply sequential barcodes, EAN codes, and QR codes directly to a pack – negating the need for separate labels and saving costs, time, and resources, all while reducing scanning errors.
Data-to-print technology also negates the need for printing plates and clichés, Mondi explains. Set-up and production times are therefore reduced, enabling new designs to be introduced and adapted at shorter notice.
This includes medium and large quantities of the same design in a single run, such as seasonal, regional, or event-related campaigns. Customers can specify the required amount of packs produced per print image thanks to optimized quantity splitting – a feature hoped to lower storage costs and prevent surpluses.
Mondi recommends digital printing for companies in the e-commerce, food and beverages, and fast-moving consumer goods sectors, among others.
Earlier this year, Siegwerk revealed its own new print series – this time nitrocellulose-free inks for surface printing on polyethylene and polypropylene packaging. The inks were designed to meet packaging design guidelines from RecyClass and CEFLEX and are suitable for both flexo and gravure printing.
Brilliant Group also unveiled its Low Migration Fluorescent Ink Base series for lithographic ink systems, intended for high-performance, food-safe, and compliant printing applications. Designed for indirect food contact, the inks claim to achieve low migration without compromising on visual appeal.
More recently, Toyo Ink Europe has revealed its Steraflex GIO flexographic printing ink. It is believed to offer ‘superb’ print and press performance on most label substrates, sleeves, and other applications where migration is a key priority.
