Additional advantages over the other similar presses include water-ink balance system and tension control system, which are Donghang's exclusive patent, exquisite printing and fastest changeover, resulting in waste savings up for increased productivity. This press provides pre-register function before starting and touch screen register in printing with 63m/min running speed, which support benefit creating for customers.
 
Main features: 
 
1. Register system: each unit is driven by independent servo motor, which guarantees high-accuracy register during high speed running; the machine is equipped with stationary image monitoring system which can realize vertical and horizontal registering with less labor cost;
 
2. Stable printing pressure: rubber blanket cylinder is equipped with eccentric bearing having double-row tapered roller structure, which realizes reliable clutch operation and stable pressure; the forme cylinder and impression cylinder are equipped with tapered roller bearings, completely eliminating up-and-down movement caused by gap between bearings;
 
3. High-strength cast iron base: the base guarantees stable and reliable printing; 
 
4. Continuous alcohol dampening system with auxiliary bridge roller: the continuous alcohol dampening system with auxiliary bridge roller ensures that the printing products are colorful and clear.
 
5. Positioning system: after inputting printing length at main console, each unit will automatically reach specified position, which reduces registering time and material waste;
 
6. More optional devices: the machine can be configured with cold foiling unit, laminating unit, die-cutting unit, waste removal unit, slitting unit, sheet-cutting unit and stack collecting unit;
