Abstract

An image (400) comprising a plurality of interlaced images (100, 200, 300) is provided, the image (400) is halftone processed according to one or more processes, and the image (400) is printed, for example, using an inkjet printer. The image (400) is halftone processed according a predetermined function depending at least in part on a gray scale level for a given pixel (630) and those nearby the given pixel (630). The predetermined function can operate on a continuous tone version or on a printed-dot model of the image (400) and may include a predetermined error filter where error is distributed to pixels corresponding to the same interlaced image from which the error accumulates. The image (400) may be post-processed to arrange dots and/or shift columns of pixels to minimize overlap error or modified to include extra pixels to align the interlaced images under the lenses.
