Abstract
A method of highly accurate printing using a web offset press, particularly suited for stereographic printing. Consistent reproductions of a composite image are produced on a paper web, and registry between the image and an embossed screen is maintained, by preshrinking (e.g., reducing the moisture content of) the paper prior to printing the composite image on the paper web. Preshrinking the paper prevents the subsequent ink drying operation from causing shrinkage of the paper and concomitant variations in the image, permitting inline formation of a screen in accurate registry with the image.
