Zusammenfassung:	The present disclosure relates to methods and apparatuses including printheads arranged along a machine direction for printing regions of advancing substrate at desired contrasts, wherein apparatuses include at least one printhead configured to print a region of a nonwoven substrate. The printhead is operated at a firing frequency and the nonwoven substrate is advanced at a speed in the machine direction under the printhead. Drops of ink having a drop mass DM are ejected from the printhead onto the first surface of the nonwoven substrate to define a printed region having a print resolution extending the machine direction, MDR (dpi), and a print resolution extending in the cross direction, CDR (dpi). In turn, the printed region includes an ink basis weight, IBW (gsm), that is equal to or greater than about 0.5 grams per square meter (gsm) and an optical density that is equal to or greater than about 0.2.
