Do you still know only glazed glass? Then you are really out.
When it comes to decorative glass, if you still know only glazed glass (screen printing), printed glass, you are really out. .
Digital printing technology was introduced into the glass printing industry as early as 20 years ago. The original print was only a single color: black, used in the automotive industry.
With the passage of time, printing technology is also more advanced. No matter how rich and complex the color is, it can be printed by digital mixing.
The first application of digitally printed glass in the construction market was in 2007, and the town’s satellites were printed on the exterior wall of the Essefield City Bank.
Since then, this ceramic ink in combination with digital printing has officially kicked off the widespread use of the architectural glass industry.
In the world, the first high-tech manufacturer that successfully invented ceramic inks and glass digital printers is the Israeli company Dip-Tech.
The key challenges of this technology include:
Develop ink color,
The richness of the species,
Non-absorptive transparent glass media printed on the surface,
The durable weather resistance of the inorganic ceramic ink is such that the ink composed of the submicron glass particles is circulated through the print head, and the like.
At the same time, the integration of graphics standard digitization and glass printing processes is a huge challenge.
So what is ceramic ink?
The ink contains highly stable inorganic pigments and special submicron glass powder particles. Dip-Tech is based on extensive research on the interaction between ink and glass. By controlling drying and microscopic analysis of finished printed glass, the performance of ceramic ink is optimized to the maximum extent from the molecular level, after high temperature tempering/sintering, The ink particles are fully melted into the glass and become integral with the glass.
After tempering, the glass can be further laminated, bent, hollowed, and low-e off-line coated.
Before explaining the technical differences between screen printing and digital printing, the weak and weak areas are popularized:
Screen printing technology - through the extrusion of the squeegee, the ink is transferred to the substrate through the mesh of the graphic part to form the same graphic as the original. Screen printing equipment is simple, easy to operate, printing, plate making simple and low cost, strong adaptability. Wide range of screen printing applications common prints are: color painting, glass, framed cover, merchandise, and printing and dyeing textiles.
Digital Printing Technology - Digital printing is the printing of computer files directly on the media, which is different from the traditional printing of a cumbersome process of a new printing method. Its features: no need for plate making, instant error correction, variable printing, on-demand printing. Digital printing is an integrated technology developed on the basis of printing technology. It uses electronic text as a carrier to deliver digital printing equipment through the network and achieve direct printing.
The workflow of glass digital printing is:
Therefore, the construction industry uses a glazed glass, usually just printing simple dots, lines, and other regular geometric patterns or colors that are repetitive, unitary.
And if you want to print any diversified designs, realistic and realistic designs, such as wood, marble, stone, texture and other materials, screen printing technology (colored glaze glass) can not be achieved.
The designer originally intended to use marble, but eventually chose digitally printed glass to maintain structural control, light transmittance control, and aesthetics, while also avoiding the danger of defragging marble fragments. The ultimate cost is affordable and more environmentally friendly than using natural resources.
The MVRDV Design Institute in the Netherlands, which never walks in an unusual way, has also presented a bold glass full-glass architecture of a farm shape.
Due to the limitation of the screen color ink layer and the screen mesh number, designers cannot achieve the effects of flexible gradient and virtual reality fusion. The limitations of screen printing have been widely recognized and the future is worrying.
At the same time, Dip-Tech glass digital printing technology has a resolution of up to 1410 DPI, and the perfect high-definition print quality makes the visual effect stunning.
Combined with the application of lighting, the entire building is even more mysterious and mysterious.
The same kind of screen printing can be used, but it costs hundreds of screens. There are many more cost-effective applications for using digital printing, such as:
In addition, it is worth mentioning that at the beginning of the article, the German municipal government building, which has been exposed to the sun and rain for 11 years, has not changed its color and firmness.
Since 2009, China has officially introduced this high technology into the construction industry. Along with the vigorous development of the Chinese construction market, many architectural landmark projects with local characteristics have attracted attention due to the use of digital printed glass.
In addition, digital printing glass has become increasingly popular in indoor (intersections, walls, floors, shower doors, etc.), home appliances, furniture, and automotive industries.
The powerful digital ceramic inks control light scattering, light transmittance, different energy efficiency, light control, temperature control, privacy levels, and anti-stick performance for the automotive industry.
Especially in the energy-saving index of curtain wall glass, digital printing glass can help designers to achieve a certain heat transfer coefficient K value or U value and shading coefficient SC (is the ability of the glass to block or resist solar energy, English is Shading Coefficient, abbreviation For SC).
The function and cost-effectiveness and added value of the functional decorative glass now far surpass that of the traditional glazed glass.
Digital printing glass completely liberates the limitations of glass design.
The idea is simple, and the principle of realization is simple. The most important thing is that the cost is widely accepted by the market.
If the pattern layout is abstract, multi-faceted and highly personalized, and the colors are rich, the cost of digitally printed glass will be much lower than screen printing.
In summary, digital ceramic printing has:
Unmatched scratch resistance, acid resistance, UV light resistance and weather resistance.
Meet industry standards for quality and durability
Non-toxic liquid green ink
Can realize any design, element
After more than a decade of development, many designers have adopted digital printing glass boldly in projects around the world. Each reflects a whole new possibility of decorative glass.
Finally, let's enjoy the examples of smart and flexible use of digital print glass in several world-renowned design studios!
