Water transfer technology

Water transfer printing technology Water transfer printing technology is the latest digital imaging technology that surpasses any printing technology. It is a special paper made of nano-materials and special environmentally friendly inks. It can print images on any solid medium. Its biggest technical advantage It does not require special equipment, is not limited by media, does not require special consumables, and does not require high temperature heating, as long as you have image input tools (scanner or digital camera), drawing tools (computer), image output tools (inkjet printers) ), plus water transfer ink and water transfer paper, you can print any image on any solid object and any curved surface at will, with vivid colors and absolute photo quality. Small investment, quick start, easy operation, suitable for all fields. As long as you buy water transfer consumables, you can learn all the techniques.

 

The principle of traditional water transfer technology:

There are two types of water transfer technology, one is water mark transfer technology, and the other is water coating transfer technology. The former mainly completes the transfer of text and pictorial patterns, while the latter tends to perform a complete transfer on the entire product surface. Cubic Transfer uses a water-soluble film that is easy to dissolve in water to carry graphics and text. Due to the excellent tension of the water coating film, it is easy to wrap around the surface of the product to form a graphic layer, and the surface of the product has a completely different appearance like spray paint. It is covered on workpieces of any shape to solve the problem of three-dimensional product printing for manufacturers. The curved surface coating can also add different textures on the product surface, such as leather texture, wood texture, jade texture and marble texture. At the same time, it can also avoid the vacant position that often appears in general layout printing. And in the printing process, since the product surface does not need to be in contact with the printing film, damage to the product surface and its integrity can be avoided.

Water transfer is a special chemically treated film. After printing the required color lines, it is sent flat on the surface of the water. Using the effect of water pressure, the color lines and patterns are evenly transferred to the surface of the product. When the film is coated, it is It automatically dissolves in water, and after washing and drying, a transparent protective coating is applied. At this time, the product has shown a completely different visual effect.

 

Production Method:

1.Images are scanned and input to the computer;

2.Print out;

3.Water treatment transfer printing;

4.Varnish;

5.Blow dry or dry naturally.

 

Computer water transfer technology background:

The research team chaired by Professor Zhou Kun of Zhejiang University has innovated the traditional water transfer printing technology, using calculation methods to "upgrade" this traditional technology, and proposed a new computational water transfer technology (three-dimensional surface precision coloring technology) ), for the first time in the world to solve the problem of accurately coloring three-dimensional objects.

 

Principle:

Using computer graphics and computer vision technology, through specially developed software, the three-dimensional design drawing is "dimension reduction" into a two-dimensional "expanded drawing", and the deformation of the water transfer film during the water transfer process is physically modeled for the first time, and then Obtain the mapping relationship between the three-dimensional design drawing and each point on the film. Then use an ordinary inkjet printer to print the two-dimensional unfolded image on the water transfer film, and then spread the film on the water surface, let the film wrap the 3D model in the water and color it.

 

Features:

Low cost, fast speed, low precision;

 

Advantage:

The removal of traditional surface coloring can only be used for objects that do not require accuracy, such as camouflage, marble and other textures. This technology has used computer graphics and computer vision technology to allow water transfer printing to "aim" and put on a arbitrarily designed color "coat" for three-dimensional objects.

 

Applicable material range:

Metal, plastic, wood, ceramic, rubber, etc.
