Patent ID: 8573731

Claim:
A method for density error correction in a print mode comprising: identifying each of a plurality of printhead elements to be used to print a row of an image; calculating a density error for each of the plurality of printhead elements identified to be used to print the row of the image; calculating a number of passes that the plurality of printhead elements will use to print the row of the image; calculating an average density error for the row of the image based on: the density error for each of the plurality of printhead elements identified to be used to print the row of the image; and the number of passes that the plurality of printhead elements will use to print the row of the image, wherein the number of passes is at least two; calculating a density error correction value for the row based on the average density error; and applying the density error correction value to adjust ink flow from the plurality of printhead elements identified to be used to print the row while printing the row.
