No single industrial coding technology covers every substrate, speed, and quality requirement. CIJ, TTO, TIJ, LCP, laser marking, and print-and-apply use different methods and have different operating boundaries. Start with the package and production line, then compare resolution, consumables, maintenance, and integration.
Main technology routes
Compare technologies on the same conditions
- Substrate: film, carton, glass, metal, and shipping cases respond differently.
- Line: speed, package cadence, installation space, and synchronisation determine integration.
- Content: dates, batch data, barcodes, 2D codes, logos, and large characters set resolution and print-area needs.
- Durability: confirm resistance to rubbing, cold, water, oil, or removal.
- Operation: consumables, maintenance, downtime, rejects, spare parts, and service support all affect long-term cost.
Narrow the options by application
Flexible packages and roll labels usually need a compact, high-resolution date or 2D code on the line. TTO, CIJ, and a material-tested laser route may all be candidates. Cartons and labels require close attention to how ink, ribbon, or laser energy interacts with the surface.
Shipping cases, building materials, and pallets place more emphasis on large characters, rough surfaces, and label placement. LCP, selected TIJ systems, and print-and-apply address those needs in different ways. For permanent, high-contrast marks on metal parts, start with fiber laser and verify surface preparation and reading requirements.
Use sample testing to choose the final route
A coating, colour, thickness, or line speed change can alter the marking result. Test with the customer's actual substrate, content, and production pace. Check clarity, position, adhesion, scan performance, and maintenance at the same time.
A technology overview helps narrow the field. The final choice depends on the combined evidence from substrate, line conditions, and acceptance requirements.
