Description:
Doctor blade is an important component in flexographic printing machines, responsible for controlling ink transfer from the anilox roller to the printing plate. It ensures a clean and precise ink application by removing excess ink from the roller’s surface.
Key Features:
- Ink Metering: Ensures consistent ink distribution for sharp and high-quality prints.
- Prevention of Ink Build-up: Removes excess ink to avoid smudging and defects.
- Enhancing Print Clarity: Helps maintain fine details and color accuracy.
