The Effect of Scanner Resolution and Bit Depth on Measuring Color Changes of Fabric In Small Color Space

In the present study, the performance of a scanner for measuring the fabric's color in a small color space of CIELAB space was evaluated using the complete factorial design. In this regard, the effect of two critical factors in the setup of the scanner, namely resolution and bit depth at different levels, on the color difference of the paired samples was investigated using analysis of variance. The evaluations showed that these two factors did not significantly affect measuring the color difference of the paired samples located in the small color space of CIELAB space. Also, the effect of the hue of the samples on the results of the scanner was investigated. It was found that the scanned samples' hue significantly affected the scanner's results. The evaluations carried out in the present research are essential in various applications, such as shade sorting.
