Printing Hazard Pictograms in a Single Pass with UV Inkjet Inks

The new hazard pictograms, which need to replace the old ones on the work floor by 1 June 2017 at the latest, consist of a red outlined rhombus with a black symbol inside. By extending a marking & coding print system to two print heads, one for black ink and one for red ink, printing these labels is now possible in a single print pass. 

Coding and marking outgrows printing of only numbers and codes. A new application is the printing of hazard pictograms for chemicals that provide information about the risk a particular substance or mixture can pose to our health or the environment. At the UN World Summit in 2002 an agreement was reached to roll out a globally harmonised hazard classification and labelling system (GHS) for substances and mixtures.  In 2008, the European CLP regulation (Classification, Labelling & Packaging) introduced a new classification and labelling system for hazardous chemicals in the European Union. The pictograms have also changed, in line with the United Nations’ Globally Harmonised System.

By extending a marking & coding print system to two print heads, one for black ink and one for red ink, printing these labels is now possible in a single print pass. In view of the very wide range of substrates that hazard pictograms need to be printed on, UV-curable inkjet inks are the best option to handle the job. Agfa has developed high-quality black and red inks that provide extremely well-controlled ink spreading on the substrate. These inks deliver high-density prints with low ink coverage thanks to their efficient pigment use. In addition, they excel through their very good adhesion and scratch resistance. 

Coding & Marking: It goes with a swing

Marking and coding plays a vital role in processes from which consumers, businesses and entire industries often benefit without realising or appreciating the challenges that the methodology can present. The segment for marking and coding is one where digital alternatives are growing in relevance and importance as a result of the dynamic for change in manufacturing processes and logistics.
