Hot‑air/IR drying is proven, compatible with many water‑based inks, and can be simpler to maintain. Choose based on ink compatibility, board construction and energy considerations.

Can I add slotting and die‑cutting later if I buy a basic flexo printer now?
Many manufacturers offer modular designs or add‑on converting modules, but retrofitting can be limited by footprint and control integration. Discuss upgrade paths with your OEM to ensure future scalability.

What are the most important maintenance considerations?
Critical maintenance areas include cleaning and care for anilox rollers, proper plate mounting and storage, regular calibration of register systems, inspection and replacement of doctor blades and ensuring drying systems are clean and functioning. A preventive maintenance plan from your OEM or dealer reduces downtime.

How do I evaluate total cost of ownership (TCO)?
TCO includes purchase price, consumables (plates, anilox rolls, inks), energy and drying costs, downtime and maintenance, operator labor, training and expected scrap/waste rates. Factor in expected throughput and revenue per box to model payback.
