The Printing Principle and Performance of Printing Machines

The printing principle of the fully automatic oval-shaped printing machine is based on screen‑printing technology: a squeegee presses ink through the mesh to form a pattern on the substrate, and automated control enables efficient, continuous production.

Printing principle
Screen stencil: Each color corresponds to a screen-printing plate with a pattern; the blank areas are sealed with photosensitive emulsion, while the patterned areas remain open as mesh openings.
刮刀 motion: The squeegee, at a set angle and pressure, pushes the paste—such as adhesive paste or water-based paste—along the surface of the screen, forcing the ink to pass through the mesh openings and transfer onto the fabric below.
Color-by-color overprinting: Multiple printing units sequentially apply different colors; after each color is printed, an IR flash dryer rapidly dries the surface to prevent smudging.
Precision Alignment: Utilizing a high-precision servo system and an industrial camera for automatic correction, this ensures flawless registration of multi-color overprinting.
Core Performance Features
High Efficiency: Printing speeds of 300–900 pieces per hour, supporting continuous production and significantly boosting throughput.
High precision: Positioning accuracy can reach ±0.05 mm, ensuring crisp patterns and precise color registration.
Modular scalability: Print heads can be added on demand (e.g., expanding from 6 colors to 16), enabling flexible adaptation to changing order requirements.
Energy efficiency and environmental protection: Utilizing water-based, eco-friendly inks, combined with sealed low-temperature baking and variable-frequency speed control technology, to reduce energy consumption.
Intelligent Control: The PLC-plus-touchscreen control system supports process parameter storage, self‑diagnosis of faults, and remote diagnostics; some models also feature AI‑based self‑learning capabilities.
Strong material compatibility: Suitable for a wide range of fabrics, including cotton, nylon, leather, and nonwoven materials, and supports various types of pastes, such as adhesive paste, water-based paste, and thermosetting paste.
