[0002] Gravure metallic ink is an ink suitable for gravure printing, especially for printing metal materials such as aluminum plates, iron plates, copper plates and stainless steel plates. This ink has excellent adhesion and uses UV-curable high-gloss ink to ensure the high quality and gloss of the printed products. Gravure metallic ink is widely used for printing on various metal surfaces, including but not limited to aluminum plates, iron plates, copper plates and stainless steel plates. Due to its high gloss characteristics and excellent adhesion, gravure metallic ink is very suitable for printing fine patterns such as trademarks, labels and decorative patterns.

[0035] In order to compare the leveling properties of the second embodiment, the third embodiment, the fourth embodiment and the comparative example of the present application, an observation test was conducted. The first substrate, the second substrate, the third substrate and the fourth substrate were completely identical. Under the same test environment, the gravure metal ink of the comparative example with a content of a was applied on the first substrate, the gravure metal ink of the second embodiment with a content of a was applied on the second substrate, the gravure metal ink of the third embodiment with a content of a was applied on the third substrate, and the gravure metal ink of the fourth embodiment with a content of a was applied on the fourth substrate. The initial states of the gravure metal ink on the first substrate, the second substrate, the third substrate and the fourth substrate were the same. After the same time, the flow states of the gravure metal ink on the first substrate, the second substrate, the third substrate and the fourth substrate were observed. The results show that the flowability of the gravure metal ink on the first substrate is lower than that of the gravure metal ink on the second substrate, the third substrate and the fourth substrate. Therefore, it can be concluded that the leveling property of the gravure metal ink of the present application is better than that of the gravure metal ink of the comparative example.

[0036] The gloss test comparison of the second embodiment, the third embodiment, the fourth embodiment and the comparative example of the present application is shown in Table 1 below:

[0037] Table 1

[0038] Measuring angle 20° GU Measuring angle of 60° GU Measuring angle of 85° GU Second embodiment 103 172 147 Third embodiment 100 169 152 Fourth embodiment 102 175 146 Comparative Example 85 150 125

[0039] The test data in Table 1 are obtained as follows: GU in Table 1 represents glossiness. The BYK three-angle gloss meter is used for testing, the BYK three-angle gloss meter is started, and then the BYK three-angle gloss meter is calibrated, the measurement mode with a measurement angle of 20° is selected, and then the BYK three-angle gloss meter is stably placed on the gravure metal surface in the second embodiment, and the displayed GU value is recorded; then the BYK three-angle gloss meter is stably placed on the gravure metal surface in the third embodiment, and the displayed UG value is recorded; then the BYK three-angle gloss meter is stably placed on the gravure metal surface in the fourth embodiment, and the displayed GU value is recorded, and then the BYK three-angle gloss meter is stably placed on the gravure metal surface in the comparative example, and the displayed GU value is recorded. Then select the measurement mode with a measurement angle of 60°, and then place the BYK three-angle gloss meter steadily on the gravure metal surface in the second embodiment, and record the displayed GU value; then place the BYK three-angle gloss meter steadily on the gravure metal surface in the third embodiment, and record the displayed UG value; then place the BYK three-angle gloss meter steadily on the gravure metal surface in the fourth embodiment, and record the displayed GU value, and then place the BYK three-angle gloss meter steadily on the gravure metal surface in the comparative example, and record the displayed GU value. Then select the measurement mode with a measurement angle of 85°, and then place the BYK three-angle gloss meter steadily on the gravure metal surface in the second embodiment, and record the displayed GU value; then place the BYK three-angle gloss meter steadily on the gravure metal surface in the third embodiment, and record the displayed UG value; then place the BYK three-angle gloss meter steadily on the gravure metal surface in the fourth embodiment, and record the displayed GU value, and then place the BYK three-angle gloss meter steadily on the gravure metal surface in the comparative example, and record the displayed GU value.

[0040] It can be seen from Table 1 above that the glossiness of the second embodiment, the third embodiment, and the fourth embodiment is greater than the glossiness of the comparative example under the same test mode, so the glossiness of the gravure metallic ink prepared by the formula of the present application is greater than the glossiness of the gravure metallic ink of the comparative example.
