Product Introduction:
Flexographic printing requires maintaining consistent contact between the printing plate and the substrate, even on uneven surfaces such as corrugated cardboard. This necessitates excellent flexibility in the printing plate. Additionally, to ensure that non-printing areas do not transfer residual ink from the plate, the non-image areas of the plate must have sufficient depth to meet this requirement.
Function of Flexographic Plate Bonding Tape:
The primary role of flexographic plate bonding tape is to secure the flexible printing plate to the surface of the printing cylinder or mounting sleeve, ensuring that the plate does not lift or shift during the printing process. This guarantees smooth and accurate printing operations.
By selecting bonding tape foam with the appropriate density, precise control of printing pressure can be achieved. This allows the flexographic plate to align perfectly with the design and text, resulting in the flawless reproduction of printed patterns and an improvement in print quality.
Additionally, the bonding tape helps balance equipment vibrations and compensates for system errors, ensuring stable and high-
quality printing performance.
