There are variations of digital decoration on glass that can be carried out according to the different types of material: Transparent decorations, Digital sandblasting and Digital Painting.
Transparent, opaque or semi-opaque decorations
With Valjet and its dedicated colour, it is possible to guarantee the total transparency of the material for decorations on polished glass.
This aspect is of the utmost importance for users interested in purchasing glass products, favouring the natural capacity of the material to visually open closed spaces: a greater visibility and brightness are only some of the benefits that can be obtained. Light architecture is by now the subject of studies for smart working and conditions of well-being at work, and it is the main reason for which the use of glass, in both the construction and furnishing sectors, is growing relentlessly.
The mechanical colour grip on polished monolithic glass is guaranteed by the special Valjet colour formula developed especially for decorations on glass.
The colour fastness is guaranteed to withstand any type of cleaning detergent used in civil and industrial processes. Moreover, it is possible to create opaque decorations to eliminate the transparency of the entire surface of the glass, or semi-opaque when an interesting frosted “peek-a-boo” effect is required.
There is the possibility to vary the degree of transparency (from 1% to 100 %) adapting the process to the user’s specific visibility or privacy needs.
The opaque option and its modulations of intensity are suitable also to meet the “sun-shading” needs to prevent an excessive amount of sunlight or light entering environments.
The reduction of visibility/transparency is used also for staircase balustrades, balcony railings, walk-in shower enclosures, staircase treads in which glass is used for its elegance, hygiene and durability.
The decoration of these elements is aimed at blending decoration and aesthetic enrichment used for either partial or total visual protection (in particular for balcony railings) for reasons of privacy.
“Valjet, by performing decorations using clear lacquer that does not contain any solid pigments, makes it possible to carry out sandblasting effects decorating on etched or sandblasted glass to achieve delicate or light tone-on-tone effects.
There are many advantages provided by sandblasting-effect decoration (or “digital sandblasting”) in terms of quality and profit. First, the need for workmanship is drastically reduced: in fact, the “traditional” sandblasting technique includes costs relating to the application and removal of the protective PVC film used to define the silhouette of the sandblasting design. In addition to these, there are the PVC purchasing costs as well as those relating to the disposal of the same at the end of the process, governed by special waste disposal laws.
An extremely important added value is surely given by the graphic and expressive capabilities of this technique, which prove to be the great restriction of “traditional” sandblasting, due to its solid, mono-dimensional nature. On the contrary, the Valjet “digital” version, makes it possible to carry out any graphic detail, even extremely small details, and the modulation of the varying degrees of the sandblasting effect enables different depths to be achieved in the same decoration.
These two techniques are very different also in the glass maintenance and cleaning stages: the traditional sandblasting technique involves a mechanical abrasion of the surface, you only need to pass your fingertips over the glass to feel it. This leads to a greater adherence of dust and, when cleaning is necessary, also of cleaning detergents. These penetrate the molecules of the glass itself, creating the bothersome circular “stain” effect.
However, with the Valjet “digital sandblasting” technique, the glass maintains its original structure and its behaviour as regards the adherence of dust and, during cleaning operations, also of detergents is not altered in any way. Finally, by using white mixed with the clear varnish, (a mix automatically created during a single process stage managed by machine software), it is possible to vary the intensity and create sandblasting effects inside laminated glass that leave the external surface of the glass unaltered, remaining polished on both sides.
The perfect definition of the Valjet system combined with the top quality of its colour formula makes it possible to carry out digital painting, monochrome or multi-coloured painting operations on Glass; these operations are all carried out “on demand”, therefore avoiding the need to store glass in the warehouse as well as waste caused by remnants of coloured glass.
The chromatic potential is considerable extended thanks to the 4/C printing process used by the system (16,800,000 colour tones compared to the RAL or similar scales that are based on dozens or a few hundreds of colours) that pays painstaking detail to the detail compared to the traditional varnishing/painting operations carried out on glass.
Thanks to the flexibility of the Valjet digital system and to the potential of the 4/C printing process, it is possible to chromatically customise the glass, using transparent, opaque or intermediate colour solutions varying the degree of opacity, creating constant solid or gradient colours.
The “chromatic customisation” of glass makes it possible to adapt, matching the colour of the fittings or glass products to the environment and the context in which it is to be installed.
Transparent colours provide an interplay with sunlight that by passing through the glass, it alters the colour of the environment itself.
Digital painting carried out with Valjet, makes it possible to manufacture small and tiny production lots with extremely low, affordable and rapid system set-up costs, thanks to which it is possible to manage the user’s requests, avoiding warehouse stock and all the resulting burdens.
The system also makes it possible to create samples and colour references for commercial management purposes as well as the defining of specifications for each work order.
