in size and are arranged in rows and columns with separations d 1 and d 2 the separations d 1 and d 2 are between about 5 u03bcm and 10 u03bcm and preferably about 8 u03bcm each cell 32 preferably corresponds to a single dot and the volume which is about 30 40 pico liters will accommodate a single droplet 34 cell density like dot density may be varied in accordance with the desired print quality although exemplary cell densities range from 75 dpi dots cells per inch and below to 600 dpi and above it has been found that excellent print quality may be achieved in the 75 dpi to 250 dpi range referring to fig3 and 4 and as noted above the cells 32 receive ink droplets 34 from the orifices of the printhead assembly printheads 50 discussed below in a pattern that corresponds to the image being produced the cells 32 include sidewalls 42 that are inclined or u201c tapered u201d with respect to bottom walls 44 at an angle of between about 120 degrees and about 150 degrees and preferably about 135 degrees it is most desirable for an ink droplet 34 to be ejected into the center of the associated cell 32 so that the droplet fills the cell and forms a meniscus 46 across the top of the cell such precise positioning of.
