Ferro’s HPLUS, unlike DG Inks, contain a significant percentage of water. This considerably reduces flue emissions compared to both Ferroinks 3.0 and DG Inks. In addition, the level of odorous emissions is one of the lowest in absolute terms, as is the total quantity of carbon measured. As is the case with DG Inks family, a limited degree of short carboxyl chain formation occurs at the flue (the quantity that is observed, in fact, is extremely small due to the firing conditions used for the samples, which are not comparable to those adopted at an industrial level, so an even smaller quantity of molecules other than water, CO and CO2 is expected).
The HPLUS inks are likewise designed to have the same rheological and colorimetric characteristics as the Ferroinks 3.0 series, although they can only be used on machines and printheads that are specially designed to function with a high water content (corresponding to a high level of electrical conductivity and a higher degree of evaporation than the 3.0 series). The HPLUS family includes HPLUS1, HPLUS5 and HPLUS10. These specific classes of inks stand out for their larger particle size compared to traditional inks. The HPLUS1 inks (with particle size of a micron or smaller . that we call HPLUS) include colour inks and material inks and guarantee the same levels of performance as applications already in use but in a water-based solution.
Inks with larger diameter particles such as the HPLUS5 are able to produce more intense colours (Marker Colors). In terms of material application, they come close to the results achieved with traditional methods but without any risk of toxicity due to the submicronic milling.
The HPLUS10 inks extend the range of possibilities in both colour and material, but they are still undergoing study, particularly regarding the correct choice of printhead. The Ferro team is excited to be introducing these new tile digital decoration ink families. We’ll be posting updates soon.
