Dust Pilling on Edge of Printing
When observing dust pilling on the edge of printing, it's important to understand the causes and implement appropriate remedies to address this issue effectively.
Causes:
1. Dry and dusty board: Using a board with a better surface quality and implementing vacuum suction to remove dust from the board can help mitigate this cause.
2. Excessive plate impression: Reducing pressure on the plate can prevent dust pilling and ensure a cleaner print.
3. Low ink pH: Checking and adjusting the ink pH is crucial to maintaining optimal printing conditions and preventing dust pilling.
4. Excessive anilox pressure on the plate: Adjusting and reducing the pressure on the printing plate can help alleviate the issue of dust pilling.
By addressing these causes with their corresponding remedies, it is possible to improve the printing process and minimize the occurrence of dust pilling, ultimately enhancing the overall print quality.
