55 PPH Fully Automatic Thermal CTP System For Offset Printing

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

Equipped with cutting-edge 256-channel laser light valve technology, this full-automatic thermal CTP machine achieves an exceptional output speed of 35–55 plates per hour for 8-up plates (1,030 × 800 mm, plate sensitivity: 100 mJ/cm²), delivering twice the productivity of previous-generation devices.

By adopting square screen imaging technology, the system significantly enhances imaging performance, offering up to a 21% increase in color saturation and 10 times higher precision compared to conventional 200 LPI AM screening. This ensures sharper edges, richer tones, and superior dot clarity.

The integration of a high-precision linear motor positioning system ensures stable performance, extended service life, and lower operational and maintenance costs, making it a highly efficient and reliable solution for modern prepress production environments.

Technical Advantages

1. Advanced 256-Channel Laser Technology
   Breaks through the limitations of traditional fiber optic systems by splitting a single laser beam into 256 individually controlled channels. This doubles the output speed while ensuring uniform energy distribution and high consistency of exposure dots.

2. High-Precision Imaging with Square-Screen Dot Technology
   Utilizes square dot imaging with sharp edges and a rectangular energy profile, delivering images that are 10 times more precise than traditional 200 LPI AM screening. The result is a clearer definition and over 21% increase in color saturation, ensuring exceptional print quality.

3. Efficient Plate Making with Lower Mechanical Wear
   While output speed is significantly increased, the drum rotation speed is reduced to just 20–50% of conventional systems. This minimizes mechanical wear, enhances durability, and lowers long-term maintenance costs.

4. Stable and Consistent Exposure
   The light valve system ensures every one of the 256 laser channels emits even and stable energy, resulting in high-fidelity dot reproduction and superior imaging uniformity across the entire plate.
