Printer optimization for lenticular screening

Digital Halftoning refers to any process used to convert continuous-tone images into an arrangement of black and white pixels, creating the illusion of a continuous-tone image. Lenticular screening is the process of multiplexing multiple images together column-wise into a single image which is then printed onto the flat side of a lenticular lens array such that from a given angle only one of the component images is visible. Lenticular screening presents a unique challenge to digital halftoning as a new generation of halftoning algorithms are needed in order to reduce the errors in lenticular prints caused by both lack of correlation between neighboring pixels and printer distortion. In this paper, we have addressed the issue of printer distortion, attempting to reduce error in lenticular prints by achieving a higher level of control over the printer being used for the print. We took into account the influence of a printed pixel on the resulting gray-level of surrounding pixels, adjusting printer resolution to account for dot overlap from various channels in order to reduce blurring within prints.
