    摘要: A page-wide array inkjet printer allocates the processing tasks for individual printheads within the array to separate halftoning processors. Each halftoning processor processes the information relating to a strip of the image, with the boundaries between strips running parallel to the print medium advance direction. In a preferred embodiment, the pixels within each strip are processed using a forward error diffusion algorithm operating along columns of pixels parallel to the strip boundaries. The resulting halftone data is supplied from each halftoning processor to one or more uniquely associated printing component controllers, and these controllers generate print instructions for printing components (e.g. inkjet printheads) connected to the printing component controllers via a dedicated communications channel.

    摘要: Methods and means for imaging on paper media are provided. A data file of an image to be printed is analyzed. A pattern for a clear fluid is determined according to the analysis. The pattern of clear fluid is applied to a paper media traveling in a particular direction, wherein the pattern is generally elongated along the direction of travel. The pattern of clear fluid is defined by a maximum width that is generally equal to the maximum width of the image to be formed. One or more colored inks are applied such that the image is formed and is supported by the paper media. The paper media exhibits reduced cockle as a result of the pattern of clear fluid.
