A2 High-Speed Four-Color Sheet-fed Offset Printing Press

This A2 High-Speed Four-Color Sheet-fed Offset Printing Press comes with high-precision double-diameter cylinders and gears, a steady paper feeding system, accurate paper registration system, and reliable ink supply system. It meets the demands for high-quality, efficient color printing which are typically required for thick paper applications. With a wide range of paper thickness, it handles everything from 0.04mm thin paper to 0.4mm thick cardboard. Equipped with a touchscreen and user-friendly user interface, the underlying intuitive design allows users to accomplish printing tasks with ease.

Product Features

1)Heavy-duty mechanical structure, which consists of major components such as cast-iron integral base, machine wall panel and cylinders, are designed with materials and structures offering excellent strength, toughness and high capability of abrasion resistance and shocks absorption. It guarantees smooth running at high-speed printing and applying uniform printing pressure during the process.
2)Lower paper feeding system and paper transfer mechanism adopt a high-point closed tooth design, which makes the paper transferring with more precision and higher reliability.
3)Double-diameter impression cylinder and triple-diameter paper transfer cylinder reduce paper handovers, therefore improves paper registration accuracy.
4)Plate cylinder and blanket cylinder running on shoulder irons contribute to greater smoothness in the printing operation and more consistency of printing quality.
5)The fine adjustment of plate in horizontal, vertical, and diagonal directions achieves a fine adjustable distance of 0.01mm increments, which greatly reduces the setup time.
6)Paper feeding head, paper table, front gauge, and grippers are specially designed to transport papers of wide range of thickness.
7)Semi-automatic plate loading and clamping system is designed to simply plate changing process, shortens downtime and therefore improves work efficiency.
8)Continuous paper feeding system is specially designed to improve paper transport for both thin and thick paper. The vacuum paper feeding table with three suction paper conveyors on it can stably transport various types of paper.
9)High-precision bearings from brand name manufacturers and precision-ground bevel gears guarantee smooth machine transmission.
10)Chrome-plated cylinders is designed to contribute to longer lifespan of presses.
11)Safety devices are mounted in plate mounting, wiping, protective cover, safety cover, and adjustment door to safeguard operators and the presses.
12)The ink roller is using pneumatically controlled clutch pressure to engage and disengage, which makes the press operating with more reliability and smoothness.
13)Paper delivery system, which is using air nozzles and suction wheels, achieved excellent quality within full range of printing speed.
14)Semi-automatic cleaning system is designed to shorten the time spent on cleaning process of ink rollers, speeds up ink changes and reduces operator workload.
15)Alcohol dampening and continuous water supply system is designed to balance ink-water level during printing process.
16)Automatic water level tracking device adjusts the water level automatically depending upon rotation speed changes of the machine.
