Abstract

The invention discloses a glass gradient spraying technology, a gradient ramp glass cover plate and an electronic product, and relates to the technical field of ink spraying. The glass gradient spraying technology comprises the following steps: firstly, using semitransparent ink to carry out whole-surface spraying according to a plurality of parallel spraying paths; then, gradually reducing a spraying area to form an ink layer with a changed thickness gradient, wherein the viscosity of the semitransparent ink is 8-18Pa.s, an interval between adjacent spraying paths is 14-18mm, a spraying swathrange during spraying is 2-3cm, spraying height is 7-10cm, and 1-3 spraying paths are reduced for each piece of glass each time when the spraying area is gradually reduced. According to the glass gradient spraying technology, a spraying process condition is optimized, the surface of the ink after spraying is smooth and flat and is free from orange stripes or wrinkled surfaces, a color gradient effect is good, transitivity and continuity are good, and no ladder feeling is in the presence.

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...
