1) Gross - derivative gas technology 2) high performance, Hypersensitive to the photosensitive layer technologyVP

Advantages: of the "High Sensitivity"; enhancing "small dot reproduction"; adopting the hypochromic principle.

Characteristics: making Photosensitive faster, reducing copy of time and greater operability; Excellent outlets resolution and the high-level networks easier reproduction; using gross gas-guided technology, shortening the vacuum-pumping time and reducing the phenomenon of the drying true and flowers. Obvious high color contrast and the sophisticated subtraction techniques facilitate drying sets and check.
