Abstract
An inkjet printer includes an inkjet printhead having a plurality of color planes for ejecting a plurality of different inks. Each color plane has a nozzle row defined in a nozzle face of the printhead and each nozzle in a respective color plane is supplied with a same ink. The printhead is plumbed such that a first color plane ejecting a first ink having a relatively low luminance is sandwiched between second and third color planes ejecting respective second and third inks having a relatively high luminance. A plurality of ink reservoirs are in fluid communication with the printhead, the ink reservoirs containing the first, second and third inks. An amount of surfactant in the first ink is at least 0.4 wt % greater than an amount of surfactant in the second and third inks.
