Abstract
-
The subject of uncertainty of spectrophotometric measurement of printed textile materials is one of the major unsolved technical problems in textile colourimetry today. Textile manufacturers are often trying to maintain colour difference tolerances which are within the range or even less than the uncertainty of the measurement system controlling them. In this paper, two commercial spectrophotometers with different measuring geometries (GretagMacbeth Eye-One Pro with 450/0° geometry and ChinSpec HP200 with d/8° geometry) were comparatively investigated in terms of measurement uncertainty in colour characterization of textile products. Results of the study indicate that, the despite of different measuring geometry, instruments had the similar measurement repeatability behaviour (repeatability of readings from different parts of the same sample) in the case of used digitally printed polyester materials. The important influence on measurement variability had the material preparation method (were the materials triple folded, placed on a black backing or a white backing). On the other hand, instruments showed difference concerning the inter-model agreement. Although this difference was not confirmed as significant with visual assessment, observers evaluated the measurement readings from the Eye-One Pro spectrophotometer as more accurate colour appearance characterization of textile materials.
