S3: and (3) adding the drier into the pigment obtained in the step (S2), and uniformly stirring to obtain the pigment.
And similar to the step S1, the stirring time is generally 30-50 min, and the stirring is uniform.
After the ink is prepared, removing bubbles generated during ink stirring through a three-roller grinder, and packaging.
The invention will now be described with reference to specific examples. The values of the process conditions taken in the examples below are exemplary and can be obtained in the ranges indicated in the foregoing summary, and for process parameters not specifically identified, reference may be made to conventional techniques. The detection methods used in the examples described below are all conventional in the industry, except for the specific descriptions. Reagents and apparatus used in the technical scheme provided by the invention are available from conventional channels or markets unless otherwise specified.
Examples
The preparation method of the embodiment comprises the following specific steps of:
first, the following materials were put into an ink stirring tank in the proportions shown in table 1: resin oil, nano calcium, medium yellow pigment, orange pigment, polyethylene wax, soybean oil, gloss oil, light oil and fluorescent paste. Then the pigment is stirred for 30min by a planetary stirrer until the color is uniform, and the pigment is fully wetted by standing for 4 h. And setting the pressure of a three-roller grinder according to the fineness requirement, and grinding for 2 times by adopting the three-roller grinder. Again, the following auxiliary agents are added in proportion and stirred for 30min until uniform: manganese as A-type drier and cobalt as B-type drier.
Table 1 raw materials used in the examples
And measuring 0.06 Cubic Centimeters (CC) of the special color ink of the mixed and evenly stirred golden larch orange by using an IGT quantitative instrument, adding the special color ink to an ink homogenizing roller of a color spreading instrument CB225A of the color, starting to uniformly ink for 70-90 seconds, and spreading the sample after the ink is uniformly rolled. The sample spreading is detected by using X-riteeXact, the target value of the color ink of the golden larch orange is set to be L75.2, a 48.3, b 67.9, C83.4 and H54.6 degrees, and the color difference value is set to be delta E <1 to be qualified. Measurement setting: measurement mode M1, illuminant/viewing angle D50/2, ΔE mode CIE Δ2000. The color and printability of the ink were determined, the color values are shown in FIG. 2, and the color value measurements are shown in Table 2. The fineness, viscosity and fluidity of the ink were measured simultaneously using a fineness plate, a viscosity meter and a fluidity meter. Finally, the dryness of the ink was determined by a drying experiment. The measurement results are shown in Table 2.
Table 2 example ink performance parameters
As can be seen from Table 2, the color ink of the yellow-orange flower provided by the invention has excellent printing performance, high brightness and high chroma.
Fig. 4 (a) shows a target orange pattern with color values 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 sample printed with the 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 color of the swatch shown in fig. 4 (b) is very similar to the color of the target orange pattern shown in fig. 4 (a).
Pantone 2018U is an orange spot color in Pantone colors, and the color value of the Pantone 2018U is as follows: l:70.0, a:41.7, b:58.3, C:71.7, H:54.4 deg.. The color is shown in FIG. 3. Which is the common color of the existing common color ruler closest to the target orange pattern color shown in fig. 4 (a).
For the target orange pattern shown in fig. 4 (a), a preview sample using Pantone 2018U color output by the image processing software is presented in fig. 4 (c). It can be seen that there is a large difference in the color of the swatch shown in fig. 4 (c) from the color of the target orange pattern shown in fig. 4 (a) (Δe=8.2).
Therefore, in this embodiment, the orange pattern shown in fig. 4 (a) cannot meet the printing requirement by using the conventional Pantone 2018U spot color, and the red orange spot color ink of the present invention can achieve the objective.
As can be seen from FIGS. 2 to 4, the color vividness, the brightness and the chroma of the color ink of the color orange of the present invention are high, compared with the color ink of Pantone 2018U.
Finally, it should be noted that: the foregoing description is only a preferred embodiment of the present invention, and the present invention is not limited thereto, but it is to be understood that modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art, although the present invention has been described in detail with reference to the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
