RY-1200 4-Color Stack Type Flexographic Printing Machine

The RY-1200 4-color stack type flexographic printing machine has a maximum web width of 1210mm and a printing width of 1200mm, meeting the demands of large-format packaging printing. With a high operating speed of 100m/min and variable plate length between 219-622mm, it flexibly adapts to diverse order requirements. The hydraulic lifting unwinding and servo rewinding systems support continuous production with Large-Diameter Rolls.

This stack type printing machine achieves industry-leading registration accuracy of ±0.12mm, integrated with Dexin Tech EPC automatic deviation correction system. It utilizes 20CrMnTi ground gears (hardness 58HRC) and NSK bearings, ensuring transmission error below 0.03mm. Independent servo drive and PLC tension control (±0.5kg) guarantee stability during high-speed operation.

The RY-1200 stack type printing machine adopts an independent four-color unit configuration: ceramic anilox roller, reverse doctor blade system, and infrared drying (adjustable up to 80°C). Equipped with a Sine PLC control system, it supports smart functions such as length counting, quantity counting, and preset stop. Pneumatic quick plate changing and self-rotating anilox roller anti-clogging technology significantly reduce downtime.

The machine features a 25mm thickened 45# steel wall plate and anti-rust painting, combining industrial aesthetics with durability. Dongming pneumatic components and Schneider electric control system comply with CE safety standards. It includes triple protection mechanisms: automatic web break detection, low paper alarm, and emergency braking.

The RY-1200 4-color stack type flexographic printing machine meets high-efficiency production needs. Its stack-type design enables quick job changeovers, offering high speed, high precision, high reliability, and user-friendly operation. The intelligent interface supports both Chinese and English languages with preset process parameters, making setup intuitive and operation straightforward—minimizing training requirements and reducing labor costs. Widely used in high-end printing applications such as food packaging, label printing, medical materials, and electronic product packaging, it is highly recognized by customers worldwide.
