Patent No. EP3691849 (titled "Method For Manufacturing An Engineered Stone And An Engineered Stone") was filed by Daltile on Oct 2, 2018. The application was issued on Mar 27, 2024.

Patent Summary

A method for manufacturing an engineered stone comprises providing a mixture of a binder and stone or stone-like material, compacting the mixture, and curing the binder. A coloring agent is added to the mixture to create a basic décor consisting of a veined effect imitating natural stone, extending through the entire thickness of the stone. Additionally, a further printed pattern imitating natural stone is digitally inkjet printed on at least a top surface. The basic décor may be created via computer-controlled dispensing into grooves or random dispersion during loading. The printed pattern may utilize organic or inorganic inks, including UV, IR, or heat-curable inks, and may be applied to edges using orientable printing heads. Optional steps include applying vacuum and vibration during compaction or forming a relief structure.
