Depending on the material used and the desired characteristics, Gravic offers several printing processes:
Screen printing provides a high-quality service which guarantees perfect colour control.
The ink is pressed through a mesh screen by a rubber rake. Some cells are open, while others are closed, to form an image area. This technology can be used to deposit ink over large areas, with large quantities of pigment.
As a result, screen printing brings depth and vivid, bursting colours, precise colour accuracy (pantone or RAL), excellent opacity, and good resistance to chemical products and external aggressions, for optimal durability.
The ink adheres to the material in a chemical reaction known as polymerisation, which makes it compatible with a wide variety of support materials.
Screen printing can also be used for printing of special glues, metallic inks or varnishes.
This process is highly repeatable, and can be used to print repeating motifs (graphics) with virtually no perceptible deformation or distortion.
Gravic was a pioneer in the development of continuous screen printing and rotative screen printing, to offer technical labels at high volumes and low cost.
Flexographic printing is a type of direct transfer printing in relief.
This technology is largely used for packaging for medium to large production series (> 20,000 pieces).
Thanks to development and tests, Gravic has been able to optimise the performance of flexographic printing, enabling it to produce technical face plates in large volumes.
This technology can also be paired with rotating screen printing to print glues, braille enamels, or plating.
Digital or electronic printing
Digital printing is highly flexible and is directly controlled by a computer, which brings savings for flashing, film, plates or screens used in traditional printing modes.
This process has many other advantages: it reduces production costs and times, and improves personalisation and management of variables such as text and images .
These low fixed costs make this process appropriate for small production runs, and also for larger quantities.
However, the number of materials and supports that can be printed on remains limited. Additionally, the uniformity, durability and resistance of printed inks to external aggressions is not as strong as it is with traditional processes.
Gravic offers digital printing using ink jet, solvent, UV or digital offset technologies.
