Zusammenfassung:	The present disclosure provides a monolithic inkjet printhead for ejecting a set of ink compositions, wherein the printhead comprises at least one substrate and the substrate comprises a plurality of ejectors each comprising: (i) a nozzle, (ii) a chamber for receiving an ink composition of the set, wherein said chamber is in fluid communication with said nozzle, and (iii) a piezoelectric actuator coupled to said nozzle for selectively ejecting said ink composition therefrom, wherein each ejector is configured to eject ink droplets of the different ink compositions with corresponding volume and velocity. The disclosure further provides a set of ink compositions per se with matched values of viscosity, density and surface tension, a printing apparatus, and methods thereof.
