An inkjet printer produces a hair-thin print image with ink drops in pixel size. That's why inkjet printers are widely used in all industries, both for direct marking of products and for label printing.

However, this often results in monochrome, mostly black, low-resolution printing with little demand on durability and appearance, as long as legibility is guaranteed. Commercially available inkjet printers for monochrome printing on conventional labels are therefore not suitable for marking jewellery and watches.

High-resolution inkjet printers with 4-colour capability, on the other hand, are a real option for the demands of the jewellery and watch industry. However, they are only suitable when label material is used that allows ink droplets to drip from the surface into the label. Only then is the print smudge and scratch resistant. Even the influence of moisture and UV radiation is no longer detrimental. Ultrasound resistance can also be achieved.
