Patent number: 8503733Abstract: Systems and methods of measuring an amount of show-through in a printed document are disclosed. The systems and methods include an imaging device that scans a back side of the printed document and scans a front side of the printed document with a blank document disposed thereon. The imaging device produces bitmaps related to the scans and calculates bit depths associated with the bitmaps. A difference array is calculated based on the differences between the bitmaps of the back side and front side scans, and the average value and standard deviation of the difference array is calculated. The amount of show-through of the document is measured based on a formula with the calculated average and standard deviation.Type: GrantFiled: November 16, 2009Date of Patent: August 6, 2013Assignee: Xerox CorporationInventors: Bryan J. Roof, Frank J. Bonsignore, Phillip S. Crispino, Jacques K. Webster-Curley
