Large A3 High-Speed Two-Color Precision Offset Printing Machine

The Large A3 High-Speed Two-Color Precision Offset Printing Machine from Weihai Printing Machinery Co., Ltd., is specifically designed to produce medium to high-end quality image prints, small to medium volume production, and two-color or spot color printing. The press is equipped with a swing-arm feeding mechanism, continuous paper feeding system and double-spring grippers, ideal for high-speed printing on sheets larger than A3 format. It handles a wide range of papers, from thin to thick ones with different surface treatments. It delivers excellent offset printing quality with high efficiency and cost-effectiveness. It utilizes a touchscreen with an intuitive interface that is easy for operators to program settings and parameters, as well as check errors and events clearly.

Product Features

1)High-precision bearings and high-precision grounded helical gears guarantees steady and smooth power transmission.
2)Chromed plated printing cylinders offer excellent wear resistance and extend equipment lifespan, therefore reduce daily maintenance costs.
3)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.
4)Pneumatic control of the clutch and clutch pressure ink rollers makes the machine's operation more reliable and stable.
5)Plate mounting mechanism has a quick positioning device and tensioning device.

6)The Large A3 High-Speed Two-Color Precision Offset Printing Machine is equipped with a heavy-duty mechanical structure consisting of a cast iron integral base, side plates, and rollers. This robust structure guarantees high strength and rigidity, as well as excellent wear resistance and shock absorption. It has been proven to run steady and smooth during high-speed operation, maintaining consistent printing pressure throughout the process.
7)Two printing towers are capable of printing two colors at one paper pass.
8)Paper transport mechanisms such as paper feeding head, the vacuum suction paper feeding table, front guide, and paper grippers ensures that the press can print on a wide range of papers from thick paper to thin paper.

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)Double-spring grippers prevent paper slippage during paper transport and maintain consistent gripping pressure during long printing runs.
11)Utilization of semi-automatic ink roller cleaning system shortens ink rollers cleaning process and speeds up ink color changes, therefore reducing the workload and improving production efficiency.
12)Alcohol dampening technology is used to ensure continuous and stable water supply, precisely controlling the ink-water balance during printing.
13)The embedded automatic water volume tracking device is used to help adjust the water volume determined based on operation speed.

14)The paper delivery device has air nozzles and suction wheels installed, this guarantees paper delivery process with quality at both high-speed and low-speed printing.
