Comparison of color gamuts among several types of paper with the same printing technology

Abstract

In this work, we have studied the relationship among the colorimetric properties of different types of paper, having different finishing and grammage. Their color reproduction capability has also been analyzed by using the same printing technology (inkjet printing). On the one hand, we have plotted CIELAB data under the illuminant D50 into constant lightness and hue-angle planes to be compared with MacAdam limits and with Pointer's real-world surface color. On the other hand, we have calculated the volume gamut of the color solid associated to each color paper gamut. Analyzing the results, we have checked that there is not any clear relationship among the colorimetric properties of paper (for instance, CIE whiteness index, etc.) and the color gamut volume associated. However, the colorimetric parameters associated to the printed sample showed a quite good linear correlation between the minimum lightness (or the maximum blackness value) of the printed color chart and the color gamut volume. In particular, the greatest color gamut volume corresponds to the glossy papers taking into account this correlation for inkjet printing.

Enhancement of flexographic print quality on bleached kraft liner using nano-silica from rice husk

“…The widest color gamut was found on kraft liner coated with 1% nano-RHS, due to having the lowest TVI value for each process color (as shown in Fig. 9) and the best color details which resulted in the widest yellow line [45]. The narrow color gamut could be due to the pale color ink that penetrated into the paper, resulting in the dark tone increases.…”

Investigating the paper dependency of laser printed colors for uncoated papers

“…The results showed that color gamuts, ICC profiles and also light-fastness is influenced by paper properties. The effect of the colorimetric properties of different types of paper on the color gamut in inkjet printing was again studied [8]. No clear relationship among the colorimetric properties of paper such as the CIE whiteness index and the color gamut volume was found.…”

“…The interaction between paper and ink, its porosity, roughness, together with optical properties such as whiteness, opacity, light scattering, and gloss must be considered in the printing process [1][2]. The effect of paper properties on the final printed colors has been investigated for a variety of papers and printers, especially for inkjet printers [2][3][4][5][6][7][8][9][10]. However, this effect is not well understood yet and needs more researches.…”

Analysis of the colorimetric properties of goniochromatic colors using the MacAdam limits under different light sources

“…Figure 3 shows the differences between optimal reflectances and reflectances from a real color sample. However, optimal colors delimit the conventional color solid of human perception, and evaluate the colorimetric quality of colorants [10][11][12][13][14][15]: when colorants approach the MacAdam limits, a greater range of reproducible colors can be obtained (color gamut). For instance, in 1980 M. R. Pointer [16,17] used these colorimetric data to compare several industrial color gamuts.…”
