Glass manufacturing process
Cromoglass identifies both the glass-printing machine and the printed glass. The printing process is quite fast (6-12 hours) and highly versatile. It is made up of the following processes:
This preliminary phase involves all the processes required by the client, such as: cutting, grinding, drilling, bending and layering.
The source file (pdf, tif or jpeg) supplied by the client or proposed by Veneto Vetro’s technical department is processed by means of a specific software, which makes it suitable for printing in terms of definition and colour rendering. For optimal results, the resolution and size of the source file must be suitable for the work to be done.
Direct printing on glass takes place by means of a large-scale inkjet plotter with 24 print heads that moves over the surface to be printed applying six different liquid ink colours at the same time. The special Double Vision technique makes it possible to print 2 different superimposed layers on glass on a single side, so that the printed colors look different on the two sides of the glass. And that’s not all: Veneto Vetro’s know-how and expertise enables it to supply an exclusive Double Face product, in which two different designs can be printed on the two sides of the glass obtaining two completely different results.
After printing, the glass is tempered or hardened, so that the image remains unchanged over time even if it is subjected to direct UV rays or atmospheric agents. The ink contains special particles and inorganic pigments that are fused inside the glass at high temperature and retain their vividness over time.
To obtain better color rendering, extra-clear glass is recommended.
Once the tempering cycle is completed and after having cooled the digitally printed glass, upon customer request, they can be laminated and / or assembled in double glazing.
Once printing is completed, the glass is carefully checked and suitably prepared for packaging. The material is identified with a label and bar code for traceability and it is dispatched. This last phase completes the production cycle and ensures client satisfaction and final quality of both the product and the service.
