UV LED-curable Inks for Digital Printing Systems

Short Description:

A type of ink that is cured by exposure to UV light. The vehicle in these inks contains mostly monomers and initiators. The ink is applied to a substrate and then exposed to UV light; the initiators release highly reactive atoms, which cause the rapid polymerisation of the monomers and the ink sets into a hard film. These inks produce a very high quality of print; they dry so quickly that none of the ink soaks into the substrate and so, as UV curing doesn’t involve parts of the ink evaporating or being removed, almost 100% of the ink is available to form the film.

Features

● Low smell, vivid color, fine liquidity, high UV resistant.
● Wide color gamut instant drying.
● Excellent adhesion to both coated and uncoated media.
● VOC free and environmental friendly.
● Superior scratch and alcohol-resistance.
● Above 3 years outdoor durability.

Advantage

● The ink dries as soon as it comes off the press. No time is lost waiting for the ink to dry before folding, binding or carrying out other finishing activities.
● UV printing works with a variety of materials including paper and non-paper substrates. UV printing works exceptionally well with synthetic paper – a popular substrate for maps, menus and other moisture-resistant applications.
● UV-cured ink is way less prone to scratches, scuffs or ink transfer during handling and transportation. It is also resistant to fading.
● Printing is sharper and more vibrant. Since the ink dries so rapidly, it doesn’t spread or absorb into the substrate. As a result, the printed materials stay crisp.
● The UV printing process doesn’t cause any damage to the environment. As the UV-cured inks are not solvent-based, there are no harmful substances to evaporate into the surrounding air.

Operating Conditions

● The ink must warm up to suitable temperature before printing and the whole printing process should in suitable humidity.
● Keep print head moisture, check capping stations in case its ageing affects the tightness and nozzles turn dry.
● Move the ink to printing room a day before head to ensure the temperature is constant with indoor temperature

Recommendation

Using invisible ink with compatible inkjet printers and rechargeable cartridges.use a UV lamp with a wavelength of 365 nm (the ink reacts best to this nanometer intensity).print must be made on non-fluorescent materials.
