Yes we do.
Many of our non-black inks have always been heavy metal free. Domino is developing a range of heavy-metal-free (and halogen-free) inks. These are designed to fulfil the requirements of the electrical and electronics industries.
By ‘heavy metal-free’ we mean that no heavy metal materials have been intentionally added to the inks. Also, we have such inks analysed, for example, by an independent testing house. We look for results demonstrating that no heavy metals are detected: the Method Detection Limit (MDL) for cadmium, lead, mercury and hexavalent chromium in the independent test procedure is 2ppm. The RoHS limit for cadmium is 100ppm and for lead, mercury and hexavalent chromium is 1000ppm.
