Digital Technologies for Express Colorimetric Assessment of the Dyed Surfaces

Abstract

Current equipment (e.g. spectrophotometers for measuring transparent environments and solid bodies in visible spectrum range) and specially developed software provide a great bulk of information about coloristic parameters: reflection or absorption spectra, trichromatic coefficients, color coordinates in various color systems, purity, color tone, color saturation, etc. However in case of multiple serial measurements only primary data on the measured color, e.g., the color coordinates or color saturation/hue are required. In this case the use of available and mobile equipment and ordinary graphic editor operating in one of the known color systems, e.g., Adobe Photoshop appeared sufficient to meet the goals. We present the results of using Adobe Photoshop and scanner HP Scanjet 5470c for scanning dyed pieces and subsequent calculation of a number of coloristic parameters.
