256 Channel Full Automatic Thermal CTP Machine with Advanced Laser Imaging Technology

Full Automatic Thermal CTP Machine With 256-channel Laser Light Valve

Equipped with a 256-channel laser light valve, this device delivers outstanding imaging efficiency—achieving an output speed of 35 to 55 plates per hour for 8-up plates (1,030 × 800 mm, Plate Sensitivity: 100 mJ/cm²), making it twice as fast as previous-generation models.

By incorporating advanced square screen imaging technology, the system enhances image saturation by 21%, while achieving 10 times higher fineness and precision compared to conventional systems.

Integrated with a high-precision linear motor positioning system, it ensures exceptional stability, improved durability, and longer operational life. This design significantly reduces overall operation and maintenance costs for the user, making it a reliable and cost-effective solution for modern printing needs.

Technical Advantages

1. Revolutionary Light Valve Technology
   This system overcomes the limitations of traditional optical fiber systems by splitting a single-source laser beam into 256 individually controllable laser channels, significantly doubling the output speed. The use of square-screen dot imaging with sharp edges and rectangular-step energy distribution delivers images that are 10 times more accurate than 200 LPI AM screening, with a color saturation improvement of over 21%.

2. Uniform Energy Distribution
   The advanced light valve device ensures that each of the 256 laser channels maintains even and consistent energy output, resulting in highly uniform screen dots during exposure. This consistency translates to stable, high-quality imaging across every plate.

3. Superior Image Clarity and Precision
   The sharply defined square screen dots enhance fine detail reproduction and contrast, producing crisper images with superior tonal gradation. This is especially beneficial for high-resolution jobs requiring excellent color accuracy and clarity.

4. High Efficiency, Low Mechanical Stress
   With 256 laser channels operating simultaneously, the system achieves high-speed plate making while the drum rotation speed remains at just 20%–50% of traditional systems, which reduces mechanical wear and extends the device’s service life. This not only boosts efficiency but also helps to minimize operational loss and maintenance costs.
