AI Technical Summary
⚠Technical Problem
Ink nozzles in ink-jet print modules for laminated packaging materials often dry out due to ink evaporation, leading to clogging and print defects, and existing methods to prevent drying, such as using humectants, can damage the substrate or require excessive drying energy.
⚗Method used
Activate all nozzles of the print module to recirculate ink and minimize evaporation by printing a control layer across the substrate, using a method that includes simultaneous activation of all nozzles and optional tickling functions to maintain nozzle integrity.
🎯Benefits of technology
Reduces nozzle latency and print defects, allowing for efficient drying without damaging the substrate, and enables a more reliable and maintenance-friendly printing process.

Abstract
A method for control of a plurality of nozzles (22) in an ink-jet print module (20), the method comprising: forwarding (S1) a paperboard web (10) continuously in a machine direction (MD), printing (S2) a décor layer (30) on a first section (11) of the paperboard web (10) using the ink-jet print module (20), and printing (S3) a control layer (40) on a second section (12) of the paperboard web (10) by activating the plurality of nozzles (22), wherein the first and second sections (11, 12) are distinct from each other.
