The aim of paper was to indicate a compatibility of results obtained from two kinds of equipment: Macbeth and DigiEye. To accomplish this, the selected materials were tested on both devices. DigiEye is a computer controlled digital camera used to measure the colour changes caused by special fabric treatment. The data that can be obtained are the reflectance or colourimetric results. The operating principle of Macbeth spectrophotometer is based on the quantitative measurement of transmission and reflection of the light by the sample. Macbeth has been used to test not only the textile materials but also for other solids and liquids since the middle of the twentieth century. Colour measurement in the CIELab system and comparison of results from both DigiEye and Macbeth indicates the differences or correlation between these two devices. The objective of this work was to analyse the possibility of a wide application of the DigiEye system in textile industry for evaluation of colour and its durability. The study demonstrated the significant differences in the results obtained from both the instruments, however, these differences follow very specific shift of the lightness, chromaticity and hue of the colour and needs further investigation.

“…The fabric is made of colored warp and weft yarns interwoven in a specific law, and the structure of the textile can be highly diverse depending on the interweaving laws, resulting in weaves that lead to different properties in the printing and subsequent color measurement of the fabric [2]. When using a spectrophotometer to measure color, the transmission of light due to the pores between the yarns resulting from the interweaving of the fabric, the reflected light collected by the integrating sphere will not be entirely provided by the object itself, but will be mixed with the reflected light from the incident light passing through the gaps and hitting the backing materials [3]. As a result, this issue occurs for color measurement of textiles as it does for transparent materials.…”

Digital printing is a new technology that combines innovative design with cutting-edge technology, and it represents a breakthrough in the field of dyeing and finishing. Silk is the most widely used medium among double-sided digital printing industry. Owing to the gaps caused by different weaving methods, silk products are generally translucent and loose in structure, therefore, the color measurement of textile fabrics also has the same problem as that of translucent materials. The final color visualization is the result of combining the fabric yarn color with the voids in the area, which make it difficult to directly measure the colors of the printed fabrics with traditional spectrophotometer. The color measurement method of double-sided digital printing was always vague, and the difficulty of measuring the color of double-sided digital printing is increased for silk, a translucent material. In this paper, sixty colors of different hues, chroma and lightness are printed on four different types of silk fabrics in order to solve this industry problem. The L * (Lightness), a * (Red/Green) and b * (Blue/Yellow)values of each color layer were measured after stacking the four types of fabrics from one to multiple layers respectively and placing them on top of a standard white board and a standard black board as a backing, respectively, to calculate the color difference between the actual color and the design color of the silk fabric, as well as the color difference before and after stacking. The fabric properties and color properties that influence fabric color measurement are then investigated. The results show that thickness is the most important factor influencing fabric color measurement, and during measuring thin fabrics, multiple layers need to be overlaid. The effect of gloss on the number of layers in fabric color measurement is inversely proportional. The b * value is not significantly correlated with color measurement, whereas L * and a * are positively correlated with the number of layers when measuring color. Moreover, based on the fabric thickness, gloss, L * , a * and b * value, the regression model was proposed, and a color measurement method suitable for silk fabrics with different fabric properties and color properties is proposed.

But Saeideh G. [4] was shown that the spectrophotometer geometry influences the color coordinates of the samples.…”
