For the labeling of numerous products the high-performance labels are required, for example in the automotive industry. When the labels will be applied in the engine compartment, they not only have to stick to a difficult substrate, but they also come into contact with chemicals. Type plates on the drills as well have to be scratch-proof and very resistant against external influences. In the technical industry the gas cylinders often stand side-by-side and, moreover, they are stored outside. The labeling is exposed to heat and cold, humidity, UV light and strong mechanical load. The label printing with the UV inkjet method is an economical solution here, especially if sorts are required in different print runs or variable data has to be also printed.
Labels which withstand high requirements could only be realized with silkscreen so far. This printing method allows for the especially thick application of ink. The ink is very resistant and durable and additionally color-intensive. When the silkscreen-labels have to be provided with variable data, then those have to be printed subsequently with thermal transfer printing in an additional step. When changing sorts, new screens will be produced and the machine must be reconfigured respectively.
The UV inkjet is a printing method which realizes the full advantages of digital printing and at the same time achieves the high resistances of silkscreen printing. Many label applications can be now produced in one step in flexible print runs and containing variable data with inkjet printing technique. Small and medium print runs as well as versions and varieties can be realized without additional costs for printing plates.
