UV inkjet labels – flexible and powerful

The economic alternative to silk screen 
UV-Inkjet Labels

The labeling market has changed – small and medium print runs in diverse versions as well as shorter delivery time and variable data printing are increasingly required. In this respect digital printing is the printing method of the first choice. It becomes exciting when high requirements will be put on the label resistance. That was the reason for Robos to decide for the investing in UV inkjet machine.

Resistance guaranteed

For applications where the labels are not exposed to an extraordinary strain, the high-quality digital printing labels can be easily used. However, for the labelling of numerous other products high-performance labels are required. That is the case for example in the automotive industry. When the labels will be applied in the engine compartment, they do not only have to stick to difficult substrates – in addition they also come into contact with chemicals. The type plates on drills as well have to be scratchproof and highly resistant against external influences. In technical industry, gas bottles stand side by side and moreover, they will be stored outside. The labeling is exposed to heat, cold, humidity, UV light and high mechanical load.

Specialized in sorts and variable data

Labels which withstand these high requirements could only be realized with silkscreen yet. 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.

Robos invests in UV inkjet

Some requirements cannot be realized economically and efficiently with the traditional printing methods. Acquiring the new UV inkjet machine by company Durst Phototechnik AG, Robos satisfies the current customer requirements.

“The UV inkjet provides us with more flexibility and freedom to offer a suitable solution to the customer”, argues Jan Strohmaier, key account manager at Robos. “The costs for plates and tapes are cut down, this way a competitive offer can be made for sorts and varieties.” Also the changes in print motif can be implemented without significant costs even shortly before the actual printing. From the experience of Strohmaier only a few customers are interested in the technical realizations of labels. They rely more on the quality of consultations of the customer consultants and on the reliability of the label printing company.

About Robos

The company Robos is located in Kornwestheim near Stuttgart and has nearly 100 employees. The label printing company already produces with two HP Indigo digital printing machines and will be even more productive with the new acquisition. The TAU 330 E, which will be placed at the new production site in Kornwestheim, combines reliability with production efficiency and produces excellent printing quality. The machine can be integrated in the current ESKO-production line, which also was an important prerequisite for Robos for the investment.

In these areas the use of UV inkjet is much in demand

  • Small and medium print runs of industrial and safety type-plates, durable electronics- and automotive labels; beverage-, body care- and household articles as well as labels for chemicals and many others.
  • Imprint of variable data onto pre-printed labels “Late Stage Versioning“.
  • Imprinting of blank labels (pre-cut labels).
  • Printing orders with variable data like e.g. consecutive numerations, texts, variable images, barcodes, QR-codes or matrix codes.

Quality and advantages, which convince

  • Fast drying of the UV-curing ink under the influence of UV light
  • Less volatile organic compounds (VOC) and odors will be released
  • The pigments-based standard UV-ink is solvent-free, which is good for the environment
  • Color gradients will be presented evenly and homogenously
  • The color tones of the PANTONE color specter can be presented very good in the expanded gamut
  • The availability of the excellently covering white color allows for numerous application possibilities on transparent and colored substrates
  • UV inkjet labels are smear- and scratch-resistant, weather-proof and resistant against abrasion, detergents and chemicals as well
