Color Mark Sensor can detect various labels accurately, even if there are slight differences in background color, and have extremely fast processing speed. The automatic adaptation wavelength of the color code sensor can detect small differences in grayscale values, regardless of the mixed colors of the label background. When using a color code sensor, it is usually required to detect only two colors of color blocks on the trajectory, namely the background color and the color code.

In the self-control systems of flexible packaging machinery, printing machinery, food machinery, textile and paper machinery, etc., color code sensors are used in conjunction with other circuits or devices to detect the presence or absence of color codes printed on a certain color background or other pattern color blocks, line objects that can be used as markers. They can achieve automatic positioning, length determination, color recognition, correction, plate alignment, counting, and other functions.
