<p>[QUOTE=&quot;SteveInTampa, post: 4644990, member: 27107&quot;]Sounds good. I believe the presses use huge drums. One drum has the intaglio engraved plates attached to it and the other drum applies the pressure to the sheet as it passes between the drums. Intaglio printing requires lots of pressure. When a sheet is mis-fed, gets folded or doesn’t get fed at all, then the inked drum, that holds the plates presses directly on to the pressure drum and leaves ink on the pressure drum....which gets applied to the wrong side of the sheet, getting fainter and fainter during each revolution.[/QUOTE]</p><p><br /></p>
