Rich solid on lightweight/low-grade paper

The surface rubber is specially designed to have high ink transfer for the lightweight and low-grade paper, and the waterless printing. Much smoother surface allows printers to achieve sharper dot structure.

Outstanding Paper Release, Easier Cleaning, Less Dot Gain

The S-PRIA Hyper Blue promises minimal dot gain as well as excellent quality of dot reproduction, paper release and ease of cleaning.

 S-PRIA Hyper Blue

Dot Gain

Testing Method

Dot gain was measured by the difference between the dot area on the plate and the printed paper.

S-PRIA compressible layer increases blanket durability

Gauge loss resistance

S-PRIA compressible layer with the even and precise air cells prevent gauge loss and maintain register control for longer time.

Testing Method
The permanent change in blanket thickness after it has been stressed 0.19 mm for 24 hours and released.

Superior shock absorption resolves printing problems

Smash Resistance (Dynamic Recovery Test)

The thick compressible layer in S-PRIA reduces the impact energy like a smash and mechanical shock on the printing press.

Testing Method
The strip of paper is attached on the sheet to increase its thickness to 0.4 mm. This sheet passes through the press, then the blanket is intentionally smashed. The press continues to print on 0.1 mm sheet. The test measures the change in ink transfer after smash.
