    • A method and apparatus is provided for compensating for variable overlap between segments of a page width print head system to reduce visually perceptible artifacts due to misalignment of adjacent overlapped segments. One method employs a summation means which sums a current dither value from a dither matrix with an overlap signal to provide an output value which is then compared in a comparator with an input continuous tone data value providing an output compensated dither value to control nozzles in the overlap region of the segments. Another method uses a software program to provide the compensated dither matrix. A sensing means provides a measure of the degree of overlap of the segments to generate the overlap signal. The sensing means may sense temperature or relative displacement of the segments. The degree of overlap may be determined for various temperatures and stored in a ROM.
    • 提供了一种用于补偿页宽打印头系统的片段之间的可变重叠的方法和装置,以减少由于相邻的重叠片段的未对准而导致的视觉上可察觉的伪影。 一种方法使用求和装置,其将来自抖动矩阵的当前抖动值与重叠信号相加以提供输出值,然后在比较器中将其输出连续色调数据值与提供输出补偿抖动值的输入值进行比较, 片段的重叠区域。 另一种方法使用软件程序来提供补偿的抖动矩阵。 感测装置提供片段的重叠程度的度量以产生重叠信号。 感测装置可以感测段的温度或相对位移。 可以针对各种温度确定重叠程度并存储在ROM中。
