Large A3 Alcohol Dampening Single-Color Sheet-Fed Offset Printing Press

Large A3 Alcohol Dampening Single-Color Sheet-Fed Offset Printing Press, equipped with an alcohol dampening system, is designed to have heavy-duty machine structures, a swing-arm paper feeding mechanism, continuous paper transport mechanism, and double-spring gripper teeth, which make the press suitable for commercial printing and packaging printing. It utilizes a touchscreen with an intuitive interface that is easy to use for operators to program settings and parameters as well as clearing errors and events.

Product Features

1)The Large A3 Alcohol Dampening Single-Color Sheet-Fed Offset Printing Press is designed to print on paper of various types including thick and thin paper, multi-part forms, and writing paper etc. It supports single color document printing and variable numbering printing with alcohol dampening system.
2)High-precision bearings and high-precision grounded helical gears guarantee steady and smoothy power transmission.
3)Pneumatic control of the clutch and clutch pressure ink rollers makes the machine's operation more reliable and stable.
4)The press is equipped with heavy-duty mechanical structure consisting of cast iron integral base, side plates, and rollers. This robust structure guarantees high strength and rigidity as well as excellent capacity of wear-resistant and shock-absorbing of the press. It has been proven that the press runs steady and smooth during high-speed operation and maintains consistent printing pressure during the process.
5)Semi-automatic ink roller cleaning system is easy to use, it shortens ink rollers cleaning process, speeds up ink color changes, therefore reducing the workload and improving production efficiency.
6)Paper transport mechanisms such as paper feeding head, paper table, front guide, and paper grippers ensure that the press can print on a wide range of papers from thick paper to thin paper.
7)Chromed plated printing cylinders offer excellent wear resistance, therefore extending equipment lifespan and reducing daily maintenance cost.
8)Safety devices are embedded in many mechanisms such as plate mounting, plate cleaning, protective covers, safety guards, and door adjustment, this is to ensure the safety of both the operator and the machine.
9)The plate cylinder and blanket cylinder on bearer rings ensure that the press produces high quality output and runs steady and smooth at high speed.
10)Plate mounting mechanism has a quick positioning device and tensioning device.
11)The swing-arm paper feeding mechanism ensures that the press is running steady and smooth at high-speed printing.
12)The press is equipped with a PLC control module and a touchscreen with intuitive program interface.
13)Utilization of Double-spring grippers is to prevent paper slippage during printing operation and to maintain consistent pressure during long printing runs.
14)The press is using alcohol dampening technology to provide continuous and stable water supply, which controls the ink-water balance during printing with precision.
