Technical Advantages of 256-Channel Spatial Light Modulator

Differing from the current optical fiber carriage, the AMSKY self-developed 256-channel laser carriage adopts spatial light modulator to divide a laser beam into 256 channels of small laser beams and achieves sharp-edged square dot imaging on plate. In comparison to conventional optical fiber technology, the average energy of each channel is easier to be controlled and the dot quality is more consistent, guaranteeing the printing quality.

DOT IMAGING, FINENESS AND PRECISION 10 TIMES IMPROVED

The square dot with sharp edge feature and a rectangular step-shaped distribution of energy used in 256-channel spatial light modulator technology makes the image clearer, 10 times more accurate than 200lpi AM screening and the color saturation is increased by over 21%. In addition, AMSKY 256-channel spatial light modulator technology can accurately match the resolution of the actual file in the circumference direction, and adjust the length and width ratio of square dot to achieve perfect variable resolution printing.

HIGHER EFFICIENCY, LOWER LOSS-OUTPUT SPEED DOUBLED

The 256-channel spatial light modulator technology can generates 180-256 channels of small laser beams simultaneously, which breaks through the limits of conventional optical fiber technology for CTP and makes output speed twice as fast as the fiber technology. This technology not only realizes rapid plate making, but also drops drum speed to 300-500rpm, only 30%-50% of the conventional optical fiber CTP. Thanks to the 256-channel spatial light modulator, the CTP has the advantages of stability, lower energy consumption and small erosion, etc.
