UV SUMMITII is made of the material given the efficiency required for the dampening roller, based on the UV SUMMIT material developed to prevent a swelling factor to the minimum limit against the strong swelling effectiveness of UV ink and UV ink cleaner.
Property |
- ① As the swelling caused of the ink is low and the anti-heat generation is good, the nipping change is small in the printing process.
- ② As the extracting and infiltrating effect of ink is almost nothing, the ink-locking or dry-blocking in particular to the UN ink is hardly occurred.
- ③ As the cleaning effect is outstanding, the color change is easy.
- ④ As it is the interchangeable-type for the UV ink and usual oil-based ink, not necessary to change a roller at each time when the ink is changed.Furthermore, refer to the following message of handling knowhow in regard to the UV Summit W and allow its performance in a full scale of efficiency.

Points to note for handling |
- ① Keep in a cool and dark room while unused.
The resin causes the particular softening degradation in case unused longtime. UV Summit II is designed taking this poing into the first consideration; however, consult with us if keeping unused more than a year. The softening degradation is estimated to come obvious in 2 or 3 years. (Keep under 30 C)
- ② Do not use the chlorine solvent and strong acid/alkali. It has a superb resistant effect for almost all the usual flushing oil, UV ink cleaner and other solvent however keep away from using the chlorine solvent such as trichloroethylene and trichloroethane, and strong acid and alkali.
- ③ In case printing with the plate in a different size (shorter size than a roller) and the roller surface may be damaged, stop using immediately.
- ④ Do not use the Kohan i.e., thickness gauge for a roll nipping control.
