As winter arrives and temperatures drop sharply, conventional CIJ inkjet printers on the market enter a high-failure period. Most standard printers have limited operating temperature tolerance. Under low-temperature conditions, they are prone to rising ink viscosity, unstable jetting, broken lines, missing characters, and ink crystallization that clogs the nozzle. Operators have to wait a long time for preheating before production, and complicated ink circuit cleaning is required after shutdown. Meanwhile, low temperature slows down solvent evaporation, making printed marks easy to smudge. Condensation caused by large temperature differences may also interfere with the photo sensor and even risk circuit board damage, resulting in frequent downtime for northern workshops and cold storage production lines.
With years of R&D and manufacturing experience in coding equipment, the Wejet CIJ inkjet printer delivers excellent environmental adaptability and operates stably from ‑30°C to +60°C. Equipped with an intelligent constant‑temperature ink system and matched special ink formula, it keeps ink parameters stable even in extreme cold, greatly reducing the risk of nozzle crystallization and blockage. It can start production without long preheating, while print drying speed and adhesion remain reliable. Whether in freezing winter workshops, cold storage lines or hot production environments, the printer continuously and stably prints production dates, batch numbers and QR codes. It simplifies routine maintenance, helps manufacturers worldwide avoid coding failures caused by extreme temperatures, and ensures uninterrupted production all year round.
