Koenig & Bauer demonstrates the VariJET 106 absorbing 3,600 offset jobs in live production at Tamir

From projection to operational reality in B1 folding carton

The packaging industry is accustomed to ambitious equipment forecasts, but the transition from vendor benchmarks to live operational data remains the definitive test for industrial digital printing. Koenig & Bauer has now crossed that threshold, presenting verified production results from Drukarnia Tamir in Poland. Following the initial installation announcement in July, the Koenig & Bauer Durst VariJET 106 is now fully operational at Tamir's Bystrzyca Kłodzka facility, actively absorbing more than 3,600 short- and medium-run jobs previously allocated to conventional offset lines.

The economic implications of this transition were detailed during a recent Digital Packaging Executive Day hosted at the Polish plant. According to the live production data presented, a single VariJET 106 is currently processing the equivalent volume of two full offset shifts within a single digital shift. This consolidation is generating verified six-figure annual savings for the packaging manufacturer, driven by drastic reductions in setup waste and lower overall production costs for short runs.

Optimizing the pressroom ecosystem

Under the leadership of President Michał Krywulec, Drukarnia Tamir operates a highly conventional infrastructure comprising nine offset presses. The strategic value of the VariJET 106 in this environment lies not in replacing offset, but in protecting its profitability. By migrating over 5.6 million sheets of short-run work annually to the digital platform, Tamir is systematically eliminating the setup bottlenecks that traditionally erode the Overall Equipment Effectiveness (OEE) of large-format offset equipment.

This hybrid production model addresses a critical pain point in the B1 folding carton sector: the inefficiency of running highly fragmented orders on machinery designed for volume. The VariJET 106, which integrates Durst's water-based inkjet technology with the established Rapida 106 platform, allows Tamir to maintain substrate consistency across both printing methods. Jobs can now be routed based on run length and economic viability without compromising the final structural or visual quality of the carton.

A validated business case for industrial digital printing

The operational data emerging from Poland provides a concrete blueprint for the folding carton sector. By utilizing the customer's actual production numbers rather than theoretical vendor maximums, Koenig & Bauer has validated the industrial business case for digital B1 printing. The ability to match or exceed offset quality on specific applications, while simultaneously freeing up massive capacity on existing conventional presses, marks a mature phase in the adoption of digital technology for heavy-duty packaging environments.
