Printing applications using classical halftoning need to resample the original image to a screen lattice. This resampling can cause undesirable moire artifacts in the screened image. Some printing techniques, e.g., gravure printing, are highly susceptible to moire, not only because of the low resolution screen lattices they employ but also because the degree of freedom in constructing half-tone dots is limited by the physical constraints of the engraving mechanism. Current resampling methods compute new samples by simple interpolation techniques that cannot prevent sampling moire very well. Therefore precautions against moire have to be made in the prepress phase, which is not practical and sometimes not feasible. A novel technique is presented to adaptively resample an image on the screen lattice using a local estimate of the risk of aliasing. The purpose is to suppress moire while maintaining the sharpness of the image. Experimental results demonstrate the feasibility of the proposed approach. (C) 2000 SPIE and IS&T.
