What is the 3D glass gradient

What is 3D glass?

The glass covers used in digital products are now divided into 2D glass, 2.5D glass, and 3D glass. 2D glass is ordinary flat glass without any curved design; 2.5D glass is flat in the middle, but the edge is curved; and 3D screen, curved in the middle or the edge.The 3D curved glass features 3C product design requirements. 3C product design, such as smart phones, smart watches, tablet computers, wearable smart products, dashboards, etc., have emerged 3D products, which has clearly guided the development of 3D curved glass. 3D curved glass is light, transparent, anti-fingerprint, anti-glare, hard, scratch-resistant, weather-resistant, etc.

It can be molded to make 3D multi-shape appearance with special design novelty and texture, and can increase the arc shape. The edge touch function brings excellent touch feeling, wireless charging function, and can solve the shortage of antenna layout space and enhance the receiving function, making the product more beautiful and excellent, and the product design differentiation makes consumers more favored.

What is the gradient?

It refers to a color gradient from light to dark objects,or from deep to shallow,or moving slowly  one  color  to the other color ,full of ever-changing mysterious romantic colors.When the design looks smooth (gradient color gives a smooth feeling), people can feel psychologically safe. Gradient colors can make our design enhance the beauty, render the atmosphere, and help us to attract more users' attention.

Gradient colors have been popular in the design field. Many of the tech companies' logos and icons, such as Instagram, iTunes, Taobao, and Meituan icons, have been designed with gradient colors.

3D Glass gradient  is mainly used in 3C products, especially in the field of mobile phones. With the prevalence of double glass and metal frames, the 3D back cover decoration process needs constant innovation. The existing decoration process is mainly to carry out coating silk screen printing on the decorative explosion-proof film, and then to match the 3D glass to achieve the decorative effect, the appearance decoration is mainly realized by the combination of the explosion-proof film texture and the coating color. Gradient effects can be achieved in a variety of ways, including: printing, transfer, vacuum coating, painting, and more. Due to the bottleneck of technology, the 3D glass grading of mass production now mainly has two ways of printing and vacuum coating.

Process flow:

First,Wash the glass,

Secod,Loading product,

Third,Coating product,

Fourth,Spraying product,


The realization of the gradient color of the vacuum coating process is mainly determined by the thickness of the optical film deposited on the surface of the substrate, and the smooth change of the thickness of the film on the same glass substrate is the key to the realization of the gradient color. Now the production process is mainly to achieve the gradient by designing the fixture and changing the correction plate.
