Abstract:
1. A method for reducing visible artifacts among image pixels formed on recording media by a plurality of individually addressable recording channels, the method comprising: operating the recording channels to form a plurality of image pixel arrangements on the recording media, each image pixel arrangement comprising a plurality of image pixel columns, wherein each of the image pixel columns extends along a first direction, and each image pixel in each image pixel column has a size L along a second direction that intersects the first direction; operating the recording channels to form a first image pixel arrangement on the recording media, wherein the first image pixel arrangement includes a first set of M image pixel columns, wherein M is an integer number greater than or equal to 1, and one or more image pixels in the first set of M image pixel columns are formed in accordance with first image data; providing second image data for the formation of a second image pixel arrangement; modifying the second image data to include the first image data; operating the recording channels to form the second image pixel arrangement on the recording media, wherein the second image pixel arrangement includes a second set of M image pixel columns that includes one or more image pixels formed in accordance with the first image data in the modified second image data; and adjusting a distance between the first set of M image pixel columns and the second set of M image pixel columns such that the first set of M image pixel columns is overlapped by the second set of M image pixel columns by an amount S along the second direction, wherein S=N*L, and N is a non-integer number selected to be greater than 0 and less than M.
