 Color is usually an essential product feature which has to be just right for customer satisfaction. A reliable method of checking and controlling product color for quality purposes is essential. But when is a color exactly right and who or what is the arbiter of this judgment?
Ultimately, it is the consumer or product user who passes judgment on the quality of a color. Human color perception determines whether the color is "right" or not. Consequently, product manufacturers have been eager to find a way to accurately simulate the human eye's visual impression in industrial color control situations.
Perceptive color sensors from Silicann Technologies recognize color in just the same way as human beings; i.e. they possess the same color sensitivity and processing method. So the sensors perceive different shades of color in the same way as the human eye.
This feature is what sets the color sensors from Silicann Technologies apart from others, since they can mimic the human eye when determining whether a color is "just right". In addition, Silicann sensors are very easy to use. With values that are easily and intuitively captured, the color tolerance of the systems can be adjusted precisely to closely resemble human perception.
