TABLE 1 raw materials used in the examples
Figure BDA0003238655810000051
0.06 Cubic Centimeter (CC) of uniformly stirred special color ink of the hibiscus brilliant orange is measured by using an IGT (ultraviolet fluorescence tomography) quantifier, the uniform color ink is added on a uniform ink roller of a color bang CB225A color developing instrument, the uniform ink is started for 70-90 seconds, and the ink is uniformly rolled and then is developed. The sample is detected by using X-rite eXact, the target value of the hibiscus brilliant orange spot color ink is set as L:75.2, a:48.3, b:67.9, C:83.4 and H:54.6 degrees, and the color difference value is set as qualified when delta E is less than 1. Measurement setup: measurement mode M1, illuminant/viewing angle D50/2 DEG, delta E mode CIE Delta 2000. The color and printability of the ink are determined, the color is shown in FIG. 2, and the color value detection result is shown in Table 2. And simultaneously, a fineness plate, a viscosity meter and a fluidity meter are used for measuring the fineness, viscosity and fluidity of the ink. Finally, the drying property of the ink is determined through a drying experiment. The results are shown in Table 2.
TABLE 2 example ink Performance parameters
Figure BDA0003238655810000061
As can be seen from the table 2, the special color ink of the hibiscus brilliant orange provided by the invention has excellent printing performance, high brightness and high chroma.
Fig. 4 (a) shows a target orange pattern having color values of L:75.2, a:48.3, b:67.9, C:83.4, H: 54.6. For the target orange pattern shown in fig. 4 (a), a swatch printed using the hibiscus brilliant orange spot color ink of the present invention is shown in fig. 4 (b). The printing stock is white double-sided offset paper. It can be seen that the swatch color shown in fig. 4 (b) is very close to the color of the target orange pattern shown in fig. 4 (a).
The Pantone 2018U is an orange spot color in Pantone colors, and the Pantone 2018U color value is as follows: l:70.0, a:41.7, b:58.3, C:71.7, H:54.4 degrees. See figure 3 for its color. Which is the universal color in the existing universal color rule that is closest to the target orange pattern color shown in fig. 4 (a).
For the target orange pattern shown in fig. 4 (a), the preview proof using Pantone 2018U color output by the image processing software is shown in fig. 4 (c). It can be seen that there is a large difference (Δ E = 8.2) between the sample color shown in fig. 4 (c) and the color of the target orange pattern shown in fig. 4 (a).
Therefore, in this embodiment, for the orange pattern shown in fig. 4 (a), the printing requirement cannot be satisfied by using the existing Pantone 2018U spot color, but the target can be achieved by using the hibiscus brilliant orange spot color ink of the present invention.
As can be seen from FIGS. 2-4, the specialty color ink of hibiscus brilliant orange of the present invention has high color vividness, high brightness and high chroma compared to Pantone 2018U.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
