“…Secondly, for applications using subtractive combination, for instance in overlapping printing, the primary colours involved are primarily cyan (C), magenta (M), and yellow (Y) . Thirdly, the historical set of primary colours commonly used in art and design, for example in oil painting, are mainly red (R), yellow (Y), and blue (B) . Fourthly, the primary colours comprised of red (R), yellow (Y), green (G), and blue (B) are widely considered as the four psychological primary colours, and they are usually utilised in the area of matching colours, for instance in the Natural Colour System (NCS).…”

It is challenging for textile designers to achieve full-colour effects in woven fabric using a limited set of coloured yarns. The common problems encountered during full-colour fabric design include an insufficient number of colours and a failure to match the fabric colour with the desired colour. Using the theories of primary colours and optical colour mixing, we examine the mixed-colour distribution of primary colour yarns on the basis of the CIE 1976 chromaticity diagram (CIE u 0 v 0 ). In our experiment, dope-dyed polyester filament yarns were selected as raw materials. Eight kinds of gradually varied weave structures and four types of primary colour combination were adopted in order to make different types of full-colour fabric colour chart. Spectrophotometer and DigiEye colour measurement systems were selected to measure the reflectance and colour value of the fabric samples. By comparing the colour distribution of mixed fabrics in the CIE u 0 v 0 diagram, the relationship between the primary colour combinations and the colour distribution of mixed fabrics is discussed. Of RGB, CMY, NCS, and RGBCMY combinations, only RGBCMY resulted in a relatively complete and large colour gamut. Moreover, the colour positions of mixed fabrics in the CIE u 0 v 0 diagram were almost all distributed on or near the connecting line of the primary colour coordinates. The specific colour position of mixed fabrics in the CIE u 0 v 0 diagram were mainly determined by the proportion of primary colours on the fabric surface. In this way, a new method for computing colour position in the CIE u 0 v 0 diagram is introduced.

“…[2] This paper mainly focuses on the former process. Many mathematical models have been employed during color characterization, such as the spectral Neugebauer equations, [3,4] Kubelka-Munk model, [5] polynomial functions based on least-squares, [6,7] artificial neural networks (ANNs), [8,9] 3D interpolation techniques, [10][11][12][13] and so on.

“…Because the reflectance data is a continuous function of wavelength within the visible spectrum, it is more accurate when Eq. [7] is written into a spectral form, and the expected a eff should make the predicted reflectance match the measured reflectance data as far as possible. Thus when the reflectance data are measured at intervals (e.g., 10 nm) and expressed as vectors, the discrete form of Murray-Davies model can be written as below: …”

Spectral Neugebauer model is widely used for spectral reflectance prediction during printer characterization. However, several factors reduce the predication precision. Thus, an improved cellular Yule-Nielson spectral Neugebauer (CYNSN) model is proposed, which modifies the traditional spectral Neugebauer model in three main aspects: (1) First, in order to adjust the nonlinearities between the predicated and measured spectral reflectance, an iteratively calculated Yule-Nielson exponent is added to the reflectance values within the Neugebauer equations.(2) Second, the quantity of Neugebauer primaries is increased by dividing the CMY colorant space into 4 3 uniform cellular subdomains. (3) Third, the mapping functions are developed to map the area coverages' theoretical values to their effective values within the subdomains, and the mapped values highly improve the matching degree of the predicated and measured reflectance values. In the experiment, four related spectral Neugebauer models are employed during printer characterization, which are the traditional spectral Neugebauer model, Yule-Nielson spectral Neugebauer (YNSN) model, traditional CYNSN model, and the modified CYNSN model, respectively. And the experimental results show the modified CYNSN model yields a significant improvement over the other spectral Neugebauer models, by comparing the characterization errors in the form of colorimetry and spectroscopy.

A special printing ink formulation based on cationic dyes is developed for digital printing of acrylic fabrics using a conventional inkjet printer. In order to investigate the contribution of color gamut boundary of printer colorants to printing efficiency, customized color targets containing 3164 color patches in 25 different hues were generated. The printed color patches were then fixed through steaming for 30 minutes followed by washing with hot soap and water and finally drying. To show the influence of dye fixation on colorimetric changes as well as color gamut boundary of samples, the L*a*b* values of color patches before and after fixation process were compared. Results demonstrate that color saturation of samples is enhanced dramatically after the dye fixation process. In fact, 3D color gamut of color patches has been drastically expanded as a direct consequence of adsorption to absorption transition. Additionally, dye fixation changes the structure of printed image from halftone superimposed dots to contone superimposed dyes. Strictly speaking, during fixation process, colors inside the halftone dots diffuse through the interfacial area to make the individual printed dots integrated. This is in analogy to the chromogenic photography films and dye-sublimation thermal transfer processes by which contone images are produced. Moreover, dye fixation improves the washing fastness of digitally printed acrylic fabrics to the level comparable with the traditional screen printing method.
