Encoding and screening electronic integral images in printing systems

摘要

A method for encoding and screening electronic integral images in a printing system includes receiving an electronic integral image having a plurality of sub-images comprised of image data, wherein at least one sub-image is spaced apart from another sub-image by a background area; adding temporary image data to at least a portion of the background area image data based on image data of one or more surrounding sub-images so as to reduce the spatial variance across at least a portion of the electronic integral image and to make it more compatible to data compression without significant signal or data loss; and subsequently removing the temporary image data added to the electronic integral image so as to reconstruct an accurate representation of the electronic integral image. A system for encoding and screening electronic integral images is also disclosed.
