Plant and process for pre-coating and printing on metallic strips

This describes a factory system for decorating metal strips. It applies a single combined primer and base coat, dries and cools it, then digitally prints using a special sol-gel ink that only needs drying. The system includes precise controls for strip positioning and print head movement to ensure accurate printing.

Why it matters: The invention's core simplification relies on a single combined coating and sol-gel ink that only requires simple convection drying. Since 2022, improvements in industrial convection drying methods or the stability of sol-gel ink formulations may have enhanced the viability of this energy-efficient approach.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedIndustrial coating, digital inkjet, ovens, cooling, control software
