Patent number: 11376840Abstract: Examples of the preferred embodiments use printed content (e.g., halftones, difference in grayscale or darkness) to determine thickness of fountain solution applied by a fountain solution applicator on an imaging member surface and/or determine image forming device real-time image forming modifications for subsequent printings. For example, in real-time during the printing of a print job, a sensor may measure halftones or grayscale differences between printed content and non-printed content of a current printing on print substrate. Based on this measurement of printed content output from the image forming device, the image forming device may adjust image forming (e.g., fountain solution deposition flow rate, imaging member rotation speed) to reach or maintain a preferred fountain solution thickness on the imaging member surface for subsequent (e.g., next) printings of the print job.Type: GrantFiled: June 26, 2020Date of Patent: July 5, 2022Assignee: Xerox CorporationInventors: Joseph C.

Patent number: 11318733Abstract: According to aspects of the embodiments, there is provided a method of determining the amount of fountain solution employed in a digital offset lithography printing system. Fountain solution thickness is determined from diagnostic images that are printed and analyzed using the existing Image Based Controls (IBC). An analysis of the density of solids, halftones, and background as a function of the fountain solution control parameter is performed to decide on the appropriate level of fountain solution. A latitude window of control parameters is then derived for which the digital offset lithography printing system in operation minimizes the undesirable effects of too much or too little fountain solution.Type: GrantFiled: June 30, 2020Date of Patent: May 3, 2022Assignee: Xerox CorporationInventors: Mark J.

Patent number: 11305572Abstract: According to aspects of the embodiments, there is provided a method of determining the amount of fountain solution employed in a digital offset lithography printing system. Fountain solution thickness is determined by examining optical density of some halftone or solid patch versus laser current level. The apparatus and method uses a variable current signal to dither or perturb the laser imaging system to irradiate a fountain solution layer to create patches at different laser current levels. An aptly programmed controller then process optical density measurements to indirectly estimate fountain solution level.Type: GrantFiled: June 30, 2020Date of Patent: April 19, 2022Assignee: Xerox CorporationInventors: David C.
