Ci Flexographic Printing Machine Central Drum Type for Packaging

This is likely caused by uneven ink distribution or unclean printing plates. Solution: Clean the ink fountain and ensure the printing plates are free of debris. Mechanical Check: If the issue persists, check the machine hardware. The plate locking cylinder may have lost pressure, or there may be excessive backlash in the plate roller gears. Hardware Fix: Refill hydraulic oil, replace hydraulic hoses, or replace the plate roller gears as necessary.

This is usually due to the ink drying speed being too slow or issues with the inverter (VFD) parameters. Solution: Use quick-drying inks or increase the ratio of the drying agent. Equipment: Our press ovens are equipped with variable frequency fans by default, so airflow is sufficient. If there is an inverter issue, please refer to the machine manual to clear the fault codes.

Yes. 'Gearless' means there is no central mechanical gear train connecting all the print decks. Instead, every axis is driven by an independent electronic synchronous servo motor, which is why it is also commonly referred to as 'Servo Driven' technology.

Our CI presses feature drying and ink systems optimized for both water-based and solvent-based inks. While technically feasible, you must ensure the solvent ink is specifically formulated for Flexographic printing. Note: Flexo inks are chemically different from Gravure inks. Using unverified or incompatible inks will lead to significant printing quality issues.

Yes. Modern water-based formulations have made significant progress. When paired with the appropriate ceramic anilox rollers, they deliver vivid colors and excellent durability. However, it is crucial to select machinery from responsible manufacturers who prioritize precision craftsmanship and high-quality components to ensure the ink performs stably.
