Patent number: 9956789Abstract: A system and method are provided for controlling archival sheet curl formation in image receiving media substrates on which images are formed using aqueous inks as the marking material. Archival curl occurs over time and is based on a partial coverage of the image receiving media substrates by the deposited water-based marking materials. A unique post-processing scheme applies selective aqueous clear fluid onto imaged substrates (cut sheets) to substantially counteract long-term archival curl formation in the individual image receiving media substrates. Both opposing sides of the cut sheet are processed in a manner that causes them to substantially equally undergo the generally irreversible shrinkage phenomenon that leads to archival curl, thus substantially canceling out the archival curl formation mechanism. A clear fluid is applied image-wise to portions of one or both sides of the image receiving media substrates to counterbalance the formed aqueous ink image.Type: GrantFiled: October 7, 2015Date of Patent: May 1, 2018Assignee: Xerox CorporationInventors: Steven R Moore, Paul J McConville, Peter Michael Gulvin, Jason M.
