With a digital printing process, sedak prints panes of up to 3.30 x 18 meters with real gold and silver.
Unlimited creativity: the printed glass can be processed further into insulating and safety glass, and can even be curved.
With its new digital printing technology, sedak can now put precious metals onto glass. The interplay between glass, gold and silver creates glass panes with fascinating optical effects – as insulating and safety glass, even curved. Especially impressive: the printing process allows for extremely fine details and filigree structures. Complex design ideas can be realized with high precision.
Two materials that have fascinated mankind for centuries are gold and glass. The elegant radiance of the precious metal and the high value associated with it combined with the bright transparency of the fragile material glass results in a unique and very unusual effect. Sedak (Gersthofen) has made this splendid symbiosis a reality and now prints glass panes of up to 3.30 x 18 meters with genuine gold and silver – with the highest precision and a resolution of up to 1024 dpi.
The printing takes place on float glass. For the printing process the gold or silver particles are bound in a special solution and applied to the glass extremely finely in a digital procedure. In the tempering process that follows the valuable metal bonds permanently to the glass.
In order to protect the printed design from environmental influences and mechanical damage such as scratches, the printed side is placed on the inside of the laminate towards the film interlayer and is thus protected by the glass.
Digital printing: fast, flexible, creative
Digital printing of precious metals offers numerous advantages compared with other procedures. Whereas with coating only full-surface application of the metal layer is possible, with digital printing even the most intricate designs can be printed: fine dots, complex patterns and even color gradients can be achieved.
There are hardly any limits to creativity: The digital gold and silver printing can also be combined with ceramic color printing, explained Theisen.
A further advantage of digital printing is the economical application of the material – a cost advantage, especially with precious metals. Gold and silver are timeless classics and exude luxurious radiance as optical highlights. Extravagant concepts for interiors and façades can be realized with the high-quality materials. Sedak's new printing technique will be used for the first time in a large project in Asia.
