0.5/0.8/1mm Underlay Blanket

0.5/0.8/1mm Underlay Printing Blanket （Printing Cushion Rubber Blanket）

The printing cushion rubber blanket is a critical material used in offset printing (such as lithography). It is typically mounted on the rollers of a printing press, serving as an elastic medium between the printingblanket and the roller. Its primary functions include cushioning pressure, and ensuring the clarity and consistency of printed patterns.

Technical Features

1. High Elasticity and Pressure Resistance

2. The cushion rubber blanket has excellent elasticity, which evenly distributes printing pressure and avoids printing defects caused by localized excessive pressure.

3. Wear and Chemical Resistance

4. Made from high-quality rubber materials, it is resistant to wear, ink solvents, and cleaning agents, extending its service life.

5. Uniform Thickness

6. Thickness tolerance is controlled within a very small range (typically ±0.02mm), ensuring even printing pressure and avoiding ghosting or blurring.

7. Tensile and Deformation Resistance

8. High tensile strength and low elongation ensure minimal deformation during high-speed printing.

9. Surface Flatness

10. Smooth and flat surface, free from bubbles, impurities, or unevenness, guaranteeing high-quality printing.
