<p>[QUOTE=&quot;clayirving, post: 2503994, member: 18867&quot;]Normally a sheet is fed into the printing press and is physically pressed by an impression cylinder into the inked printing plate to produce the intaglio print. If there is some type of misfeed of the sheet, then the inked plates make direct contact with the impression cylinder and the inked impression of the plate sticks to the impression cylinder. The next sheet fed into the press receives the expected printed image, but the inked image on the impression cylinder is also printed on the opposite side of the sheet. The first few sheets have sharp images and each subsequent sheet eventually removes all the transfer ink on the impression cylinder.[/QUOTE]</p><p><br /></p>
