Abstract

The invention discloses a glass gradient spraying process, a gradient color glass cover plate and electronic products, and relates to the technical field of ink spraying. Gradient glass spraying process includes the following steps: use translucent ink to spray the entire surface according to several parallel spraying paths, and then gradually reduce the spraying area to form an ink layer with a gradient thickness; the viscosity of the translucent ink is 8‑12Pa.s ; The distance between adjacent spraying paths is 14-18mm; the spraying width range during spraying is 2-3cm, and the spraying height is 7-10cm; when reducing the spraying area successively, each glass reduces 1-3 spraying paths each time. The invention alleviates the defects of uneven surface after spraying by the conventional spraying method and poor transitional appearance effect of gradient color. The invention optimizes the conditions of the spraying process, so that the surface of the ink after spraying is smooth and free from orange lines and wrinkles, the effect of color gradient is good, the transition and continuity are good, and there is no sense of step.

Description

technical field [0001] The invention relates to the technical field of ink spraying, in particular to a glass gradient spraying process, a gradient glass cover plate and electronic products. Background technique [0002] At present, gradient colors have been widely used in daily life. With the development of the times, the public's perception and preferences of colors are also changing. Gradient colors are gradually being applied to various fields, including UI interfaces, brand logos, posters, illustrations, and fonts. [0003] With the development of smart phones, customers not only have higher and higher requirements for mobile phone functions, but also higher and higher requirements for the appearance of mobile phones. Gradient color slowly transitions from one color to another, which is a kind of infinite change Mysterious and romantic colors are increasingly used for smartphone back covers and watch cases, and are loved by consumers. [0004] The current gradient eff...
