Structure of the 'S-PRIA Series'

Performance of the 'S-PRIA Series'

High Durability

The new compressible layer dramatically increases durability

New rubber compound and precise air cells prevent gauge loss and provide great rebound property of the compressible layer.

Gauge Loss Resistance

Testing Method
The permanent change in blanket thickness after it has been stressed 0.19mm for 24 hours and released.
Assessment
S-PRIAs show lowest deformation that helps to maintain print quality and register control for longer time.

Smash Resisitance

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.
Type of Paper : Coated paper 128g/sqm
Ink : Conventional Black
Pattern : 100% Solid (Density 1.5)
Printing Pressure (B/I)  : 15/100mm
Assessment
S-PRIAs show lowest change and quick recovery, and that proves great resistant to smash and mechanical shock.
High Efficiency

An outstanding paper-release enhances efficiency

Superior surface-rubber quality offers outstanding paper-release.
In addition, a reduction of paper dust buildup improves efficiency.

Release

Testing Method
The amount of curl height at the tail of sheet.
Type of Paper : Coated paper 128g/sqm
Ink : Conventional Black
Pattern : 100% Solid (Density 1.5)
Printing Pressure (B/I) : 15/100mm
Assessment
The amount of curl in S-PRIAs is minimal and both blankets provide outstanding paper-release.
High Quality

Improved surface rubber ensures higher print quality

Newly developed surface rubber offers excellent ink transfer that makes further improvement in half-tone dot reproduction.
With better solid density, both blankets produce outstanding printing.

Half-Tone Dot Reproduction

Assessment
Both the half-tone dots and solid density are superior, also in waterless printing and high resolution printing.

Dot Gain

Assessment
The amount of dot gain with both the S-PRIAs is minimal and half-dot printing is outstanding.
