company news about Does your carton flexo printer slotter die cutter constantly have ink streaks?

Read this article to learn about frequent issues and solutions. The following are some efficient strategies to prevent ink streaking in flexo printer slotter die cutters:
Common ink streaking phenomena include:

1. Drum bearing wear: Ink streaking traces will form on the cylinder surface due to sliding friction when the offset cylinder bearing is significantly worn.
2. Hard lining and sliding phenomenon: Sliding phenomena that occur during the printing process are the reason for ink streaking when hard lining is employed.
3. Gear wear: Due to the roller gear's extreme wear, the gear side clearance is very large. The gear vibrates when the roller is forced together, and ink streaking results from the sliding friction on the roller surface.
4. Excessive pressure: The flexo printer slotter die cutter's rubber cloth cylinder and plate cylinder are under too much pressure, which squeezes the rubber cloth and creates a significant friction sliding. This causes the layout dots to expand longitudinally and streak with ink.
5. Gear contamination: In addition to causing ink streaking, contaminants including paper hair and ink skin are embedded between the gears.

Effective strategies for avoiding
1. Replace the roller bearing: To guarantee the roller's regular performance, the severely worn roller shaft should be replaced as soon as possible.
2. Modify the packing pad: To improve the packing's elasticity and lessen the likelihood of sliding phenomena, use soft pads.
3. Modify the gear: To guarantee precise gear meshing and lessen vibration and sliding, appropriately decrease the tooth side clearance or the gear center distance.
4. Manage printing pressure: Adjust the pad thickness in accordance with the equipment's requirements to steer clear of too much pressure and stop ink bars from appearing.
5. Strengthen cleaning and maintenance: To lessen the effect of pollutants on printing quality, clean the flexo printer slotter die cutter on a regular basis. This will guarantee that the gears, rollers, and other parts are clean.
6. Modify the ink: If the ink has too much viscosity, dilute it with additives and make the necessary adjustments to lower its viscosity and lessen friction and sliding while printing.
7. Select the appropriate paper: To enhance printing quality and successfully prevent quality failures like powdering, tugging, bubbling, and peeling on the paper surface, use high surface strength and high-quality paper.
