DIANO/LSCE automate system

The uniformity was assessed by selecting representative samples from the dyed lot and determining the color (tristimulus values) on a standard colorimeter (DIANO/LSCE Automate System). The difference in color of each specimen from the average color of all specimens was determined using the FMC II color difference formula (5J. In this system one unit of color difference is defined as the minimum perceptible difference in color. Thus spots or unlevel dyeing could be readily identified by variations in color difference between specimens from the same dyeing. 

The sequence is detailed in Table XIV. No unexplained problems were encountered during the sequence. The hosiery quality was judged acceptable and was later sold by the plant as first quality. Quantitative color difference calculations using the Diano LSCE Automate System and the FMC II Color Difference Metric Program confirmed that the hosiery fell below the three to seven MacAdam unit tolerance range that had been deciphered for the company (Table XIV). The sequence thus confirmed that on a pilot-scale basis the modified procedure was practical.
