Patent ID: 7119928

Claim:
A halftone cell of a threshold array halftone screen, comprising: a plurality of pixels arranged into at least one row of pixels, each pixel having a first dimension along a high-addressability direction and a second dimension along a low-addressability direction; and a plurality of high-addressability pixels defined in each of the plurality of pixels, each high-addressability pixel having a first dimension along the high-addressability direction and a second dimension along the low-addressability direction, where a ratio between the first and second dimensions of the plurality of high addressability pixels defines a high-addressability factor; wherein: each high-addressability pixel is divided along the low-addressability direction to define a plurality of subcells of the pixels of the halftone cell, each subcell having a threshold value, the plurality of subcells of each of the at least one row of the halftone cell arranged into a plurality of subrows; and each of the plurality of subrows is selectable as the set of threshold values for the high-addressability pixels of the halftone cell to at least effectively shift the halftone cell along the low-addressability direction by an amount corresponding to the selected one of the plurality of subrows.
