FIG. 1 illustrates one embodiment of an inkjet printing system
10. In one embodiment, inkjet printing system
10 adjusts ink delivery system (IDS) pressure based on the image density and nozzle firing frequency. Inkjet printing system
10 includes an inkjet printhead assembly
12, an ink supply assembly
14, a mounting assembly
16, a media transport assembly
18, and an electronic controller
20. At least one power supply
22 provides power to the various electrical components of inkjet printing system
10. Inkjet printhead assembly
12 includes at least one printhead or printhead die
24 that ejects drops of ink through a plurality of orifices or nozzles
13 toward a print medium
19 so as to print onto print medium
19. Print medium
19 is any type of suitable sheet material, such as paper, card stock, transparencies, Mylar, and the like. Typically, nozzles
13 are arranged in one or more columns or arrays such that properly sequenced ejection of ink from nozzles
13 causes characters, symbols, and/or other graphics or images to be printed upon print medium
19 as inkjet printhead assembly
12 and print medium
19 are moved relative to each other.
