When using ceramic frit based inks the glass is fired or tempered to fuse the inks with the glass. Due to the extreme temperatures of this process there is first a decomposition of organic additives and binders of the ink. Next there is a fusion of the frit to the substrate and pigments followed by the expulsion of voids to give a compacted structure. Lastly there is a formation of a surface with the desire properties. A successful firing of the glass and ceramic ink will result in a bubble free layer of constant thickness and homogeneous pigment dispersion within the glass. |

Like other printing on glass methods, it uses a form of printmaking. Digital ceramic printing on glass has allowed for new possibilities and improvements in flat glass decoration and treatment[1] such as high levels of customization, translucency and opacity control, light diffusion and transmission, ability to calculate solar heat gain co-efficiency,[1] electrical conductivity, slip resistance, and reduced incidences of bird collision.

Essential elements
Digital glass printer
The digital glass printer is a flatbed digital printer designed with print heads to jet ceramic inks directly onto the glass.[5] The glass remains stationary while only the printer carriage sweeps across the print table. A key feature of the printer is drop fixation in which ink droplets are dried immediately to prevent drop gain. The fixation of the ink enables a single pass of the print carriage even when printing multi layer and multi color files. The drop fixation makes inline double vision printing possible. Double vision is creating a different vision depending on which side of the glass is being viewed it is achieved by printing different graphics one on top of the other. An inline dryer was developed for real time drying to occur and to maximize factory space. A smooth color switching system in included so machine operators can easily shift between print jobs and increase throughput. The high resolution print quality - up to 720 dpi - and the precision of the printers allow glass processors to print anything from fine, sharp, small elements to complex full color images on glasses up to 3.3X18 meters in size.[4]
Digital ceramic inks
The inks used in digital printing on glass mimic the CYMK color model and are comprised of ceramic frit and inorganic pigments and elements. The development of inks is a highly controlled production process to remove any variability in the final product. The consistency in replication of the inks results in high compatibility with the entire color palette of inks. The inks can therefore be digitally mixed and designers will know the precise outcome of the color every time. Printed glass panels can also be replaced when necessary without the risk of the new panels not matching the colors of the existing panels. The inks are also fully integrated with the machine and the image processing software meaning the development and the application of the inks required innovations both in science and technology.[4]
Image processing software
The image processing software bridges the glass printer and the inks and is also the design tool for preparing the graphic file for printing. The software is more than a photo raster ; it calculates ink usage to control levels of translucency and opacity, to control color matching and mixing, and to compensate for different glass sizes and thicknesses. The precision and complexity of the calculations and measurements executed by the software allows designers can achieve their desired outcome. Digital ceramic printing on glass has expanded the options for printing on glass. UV and silk screen printing have limitations that the digital printing overcomes. Digitally printed glass can be applied both to interior and exterior surfaces, the most simple to complex graphic illustrations can be printed in the CYMK color model.[5]
