Spectrophotometer in Dyeing house
• The spectrophotometer is a device that measures the light intensities as a function of wavelength.
• In dye houses, a spectrophotometer is used to analyze the color of a sample, and also to arrive at a recipe for dye mixing.
• The spectrophotometer can also quantify the difference between an achieved color and its original standard. These differences are called Delta E (error) Values.
• So there's a separate Delta E Value for Hue, Value, and Chroma.
• The delta acceptance levels are sometimes specified in customer’s quality manual.
Three things are necessary to discern color:
• The object (sample)
• The observer (the person’s eyes, or the camera’s processor)
• The light source called illuminant and it could be natural sunlight or artificial light from a lamp.
