This document discusses decorating fibre cement boards and concrete panels using digital inkjet printing with inorganic pigmented inks and coatings. It outlines KERAjet's development of this printing technology from 1997 to the present, including the creation of new print heads and production lines that allow single-firing decoration. The decoration process uses primers, inorganic pigment inks applied via inkjet printing, and coatings to provide long-lasting decoration for construction materials in a simple, cost-effective manner.
