Depending on the support to be used and the characteristics demanded by the client, Gravic proposes several printing procedures:
Silk-screen printing offers high-quality performance and guarantees perfect colour control.
Ink is pushed through a mesh screen by a rubber scraper. Some cells are open, others are closed, thus forming an image zone. This technology allows to transfer considerable quantities of ink, highly saturated with pigments.
Therefore, silk screen printing offers depth and a vivid colour rendition, precise respect of shades (Pantone or RAL), excellent opacity, high resistance to chemicals and external aggression, providing an optimal durability.
The ink adheres to the material by way of a chemical reaction called polymerization, which makes it compatible with a wide range of materials and supports.
Silk-screening can also be used to print with adhesive, metallic ink or specific types of varnish.
This procedure offers great repeatability and allows printing motives (design elements) in a repetitive way, guaranteeing that the distortion is almost imperceivable.
Gravic was a forerunner in the development of continuous and rotary silk-screening in order to propose large-scale production of technical labels et a reasonable price.
Flexographic printing is a kind of direct transfer printing, in relief.
This technology is generally used in the domain of packaging, for medium- or large-scale production (> 20 K pieces).
By way of development and testing, Gravic has found the way to optimize the performance of flexography, which makes it possible to fabricate technical front panels in large volumes.
This technology can furthermore be combined with rotary silk-screening, thus making it possible to print adhesive, relief coating (braille) or gilt.
The highly flexible digital printing is directly operated by a computer, thus sparing image-setting, films, plates and screens used in traditional printing methods.
This procedure has a number of advantages such as reducing costs and time of fabrication, personalizing and treating variable data ...
Due to the fixed low costs, the procedure is adapted to small print runs, but also to more considerable quantities.
The number of supports and printable materials remains, however, limited. What is more, the consistence of print quality, the durability and the resistance of colours to external aggression are less elevated than in the case of traditional methods.
Gravic offers digital printing with solvent-based or UV ink jet technology as well as digital offset.
