1. The semi APC (Automatic Plate Changer) shortens the make-ready time.
2 . To preset paper thickness when printing different kinds of paper. To adjust printing pressure in every unit automatically, quickly and synchronously.
3 . Impression cylinders with double-diameter and transfer cylinders are better for printing of thick paper. At the same time reduce the times of paper handover, it is better for registration.
4 . Three directions (circumferential, lateral, diagonal) loading plate error can be controlled by centralized control of DC electric plate control, which is convenient and quick calibration of four-color printing plates.
5 . Excellent alcohol dampening system, achieve the quick ink-water balance and reduce paper consumption.
JD4740 folio four-color offset printing machine features short water and ink roller distances to enable a more economical printing with low, or no, alcohol. Suitable for middle format and 0.06-0.6mm thick paper, 12,000 sheets per hour for high production packaging printing.
* Designed for middle sizes paper printing - greater printing flexibility
