1. Air brushing
The technique of atomising a varnish, breaking the liquid down into small particles, transported by air or nitrogen onto the surface of an object. This air-brush technique is widely used and is extremely flexible, whilst dealing with a range of shapes and forms. This is perfect for 3D varnishing. It is possible, with high-viscosity varnishes with a 100% dry extract to use high pressure pumps to replace the action of the transport medium.
2. Enduction printing
The technique of enduction is generally used for rolled films. An engraved cylinder is coated with the varnish, which fills the depressions in the cylinder. The film is brought into contact with the cylinder, which transfers the contents of the depressions to the film itself. This continuous process produces homogenous coatings of UV varnish just a few microns thick, giving specific properties.
3. Screen-printing (serigraphy)
This discontinuous process uses a flat screen and a calibrated mesh. Certain sections of the mesh are blocked to stop passage of the ink, while others are left open. We produce 100% dry inks for this process, which are used on a wide range of supports for an equally wide range of applications.
This continuous printing process also needs specifically-designed inks (resembling those used for screen printing), which can be manufactured on demand.
