Many established corrugated board factories already have complete converting lines that handle cutting, creasing and finishing efficiently. When demand for custom printed boxes grows, plant managers face a difficult choice: invest in an entirely new printing line, or continue outsourcing digital work and losing margin and control.
Full line replacement involves enormous capital cost, long installation downtime and disruption to existing production. Most plants also do not need full digital capacity across their entire order mix, making a dedicated line difficult to justify financially.
Retrofit single pass printing for existing lines
A targeted single pass digital inkjet printer retrofit offers a more practical approach. Instead of replacing the entire line, a digital printing system integrates into the existing production flow, adding full color digital inkjet capability where needed.
Our single pass corrugated printing machine FocusInc Cobra-1209S and Cobra-1815S models support fully customizable infeed and outfeed systems designed to match your existing board line speed and height. Optional dust removal and auto conveyor feeding handle corrugated board surface quality issues, ensuring consistent ink adhesion without modifying upstream equipment.
The retrofit approach preserves all existing converting capabilities while adding digital print flexibility. Plants can continue running standard pre-printed work through the line as before, and switch to digital post-printing for custom orders, variable data or short runs.
Financial and operational advantages
Retrofit installation requires only a fraction of the capital investment of a full new line. Installation and commissioning happen during scheduled downtime, minimizing disruption to regular production. This makes digital capability accessible to plants that could not justify a full dedicated line.
It also allows incremental upgrade paths. Plants can start with a base configuration and add options such as variable data modules or roll to roll printing as other demand grows.
Applicability boundary: This solution is designed for plants with existing board converting lines seeking to add digital capability. For greenfield installations, a dedicated complete line may offer better integration.

FAQ
Q: What board thicknesses can the retrofit system handle?
A: With optional board handling and dust removal, the system handles standard corrugated board thicknesses common in converting lines.
Q: Do I need to modify my existing converting equipment?
A: Generally no. The print station matches existing line speed and height, working as an inline add-on without upstream changes.
Q: Can a single pass printer integrate with my existing corrugated board line?
A: Yes. With custom infeed and outfeed conveyor solutions, Cobra series printers integrate into most existing board production lines without full rebuild.
Q: How long does a retrofit installation take? configuration.
A: Most retrofits install during scheduled production downtime, with minimal disruption to regular operations. Exact timing depends on line.
