“…With the original color management, the average color difference of the color checker was 20.834, and with the FPO method, the average color difference was 5.254, which indicated that the color difference was greatly reduced. Compared to the optimal color reproduction method proposed in related research, 11 which yielded an average color difference of 7.3, the color reproduction effect was further improved with the use of the FPO method.…”

“…For the yellow ink, the fitting equation is given in Equation (10), and the inflection point of the slope was at x ¼ 80:31, so the yellow ink limit was determined as 80% y ¼ 7E À 08x 3 À 0:00002x 2 þ 0:0015x À 0:0066; R 2 ¼ 0:9979 (10) The fitting equation of the black ink was obtained as given in Equation (11), and the inflection point of the slope was at x ¼ 133:33. Since the maximum ink output of the printing machine is 100%, the ink limit for black ink was set to 100%…”

“…The spectral reflectance of each color patch at 400-700 nm in the sample printed with the four-color gradation color card (CMYK) shown in Figure 3 was measured to study the dot gain in printing. Figure 13 shows the output dot area coverage calculated using Equation (11), in which the output dot area coverages of the four single-color inks were all greater than the input dot area coverages, demonstrating the phenomenon of dot gain.…”

“…Wang 9 took silk as the substrate, analyzed the influence of solid density, reproduction gradation tone and gray balance on the color of digital printing, found the correlation between various factors and carried out integrated control, which may be useful for accurate color reproduction. Huang et al 10 and Li et al 11 respectively experimented on the ink limit with cotton fabric and polyester fabric and generated ICC profile curves on this basis, and the printing color difference was significantly reduced. Guan et al 12 maintained a good linear relationship between the color yield rate and ink limit by correcting the color density and adjusting the gray balance, which improved the printing quality.…”

In pigment ink digital printing, the color difference between the original and the printed product can be visible due to the varied color gamut of devices and the impact of fabric characteristics on the color-presenting effect. To improve the color reproduction accuracy of digital printing, two methods, the full-process optimized (FPO) method and the neural network aided original adjustment (NNAOA) method, were proposed to reduce printing color difference during the color-transferring process. The FPO method, based on accounting for the fabric type and the characteristics of the printing machine, was proposed by optimizing the printing parameter settings in the color management process. Here, the optimal single-channel ink limit was determined and dot gain was compensated using the inverse function correction method, and then the International Color Consortium profile was generated. After using the FPO method, the color difference between the printed sample and the original was reduced from 20.8 to 5.254 compared with performing the original color management. To reduce the reliance on personal experience in color adjustment, the NNAOA method was proposed and implemented for 20 color patches with the largest color differences in the FPO method, allowing the color of the originals to be adjusted with the establishment of the general regression neural network model. This method predicted the input CMYK values of the original using measured L*a*b* values for the printed sample. The results showed that the color difference of the 20 color patches was reduced from 8.54 to 6.60. Consequently, both methods offered distinguishable improvements in the color reproduction effect.

The error function solution of the diffusion equation with the constant surface concentration was derived by the heat kernel to determine the constant diffusion coefficient for diffusion satisfying the infinite dye-bath condition. For the sublimation diffusion of disperse dye in paste into PET film using the film-roll method, the constant surface concentration was determined from the concentration distribution, and the diffusion coefficients of each layer were obtained by the constant surface concentration from the error function solution. When comparing the diffusion coefficients between the layers and comparing the mean diffusion coefficients for different times at a specific temperature, the constant surface concentrations determined from the quadratic regression curves for concentration–distance plots were more appropriate than those determined from the steady-state concentration distributions, which was also confirmed by the plots of concentrations obtained from the error function solution. At a specific temperature, the average of the mean diffusion coefficients obtained by the constant surface concentration of the quadratic regression curve at three specific times matched well with the constant total-amount diffusion coefficient obtained by the slope of the linear regression line for the plot of total amount against square root of time, which was confirmed by their Arrhenius plots.

Universal financial and social systems have radically transformed the essence of social commerce in addition to the commission of higher education. Executive pedagogical initiatives, comparatively cultural fabrics and garments, are eventually accountable for assembling students to be production-primed and, consequently, divergent syllabi have been established to direct this contemporary demand of the production (Abbaspour & Zare, 2023). Specifically, social observational education has been depicted to be effective at student education; foreign observation education has become renowned in the social learning composition. While greatly prior social research has enrapt on the procedures and results of contemporary syllabus, the social research probed students bulletins from a short-term social inquiry on-deck syllabus to represent how students comprehend, theorize, re-cogitate on and inquire with contemporary social observations downward a pedagogical social education theory structure (Csok, 2022). However, eight social threads appeared; two from each of the four social education modes. The findings are deliberated and the social research is analyzed with presentations, ramifications and future social research chances.
