Hello everyone. I have just graduated and have been working in the polyester industry for half a year. The B and L values are quite important in slice analysis, as they directly affect the adjustment of process parameters in production. I would like to ask what the meanings and ranges of the B and L values for polyester PET slices are Thank you!
The L value indicates black and white; it is also said to represent lightness and darkness, with + indicating a tendency toward whiteness and – indicating a tendency toward darkness. The B value represents yellow and blue, with + indicating a tendency toward yellow and – indicating a tendency toward blue
Thank you so much! Received. In analytical chemistry as well, I saw at the end that it is expressed as color values
