Enhancement of Adhesion and Wettability
Characteristics of SS-30
- 1Enhancement of adhesion
- SS-30 treatment enhances the adhesion to emulsions significantly. In particular, it is effective in printing halftone dots and fine lines.
- 2Enhancement of wettability
- As the wettability increases after SS-30 treatment, ink passes through a printing plate smoothly to enhance the reproducibility of printing.
- 3Enhancement of resolution
- The resolution is enhanced after SS-30 treatment allowing exposure time to be reduced by 30% or more. In addition, the latitude of appropriate exposure time also becomes wider.
- 4Environment-friendly treatment
- SS-30 treatment has minimal impact to the environment as it does not use any chemicals or resin during treatment.

Anti-Static
Characteristics of Super Fine
- 1Strong antistatic effect
- Strong antistatic effect is achieved after Super Fine treatment, adhesion of dirt and dust, as well as the scattering of ink during printing, can be prevented to enhance workability significantly.
- 2Enhancement of adhesion
- The Super Fine treatment enhances the adhesion to emulsions significantly. In particular, it is effective in printing halftone dots and fine lines.
- 3Enhancement of wettability
- Wettability increases after Super Fine treatment and inks passes through a printing plate smoothly to enhance the reproducibility of printing.
- 4Enhancement of resolution
- Resolution is enhanced as less halation occurs and strong adhesion to emulsion is achieved after Super Fine treatment. It enables significant reduction of exposure time (in the case of dyed items), resulting in wider latitude of appropriate exposure time.
- 5Environment-friendly treatment
- Anti-static treatment has minimal impact to the environment as it does not use any chemicals or resin during treatment.
