Method and device for controlling fountain solution thickness on an imaging surface using a capacitive proximity sensor

An ultra-high resolution capacitive sensor affixed above an imaging member surface measures the thickness of fountain solution on the imaging member surface in real-time during a printing operation. The sensor is considered ultra-high resolution with a resolution high enough to detect nanometer scale thicknesses. The capacitive sensor would initially be zeroed to the imaging member surface. As fluid is added, the capacitive sensor detects the increase and can measure and communicate with the image forming device to adjust fountain solution flow rate to the imaging member surface and correct for any anomalies in thickness. This fountain solution monitoring system may be fully automated. The capacitive sensor may have a resolution (e.g., as low as about 1 nm resolution) of about 0.001% of the distance/gap that the capacitive sensor is mounted away from the imaging member surface.

Component part comprising wear indicator

A component part for use in printing presses or paper- and substrate-processing machines, wherein the component part has at least one first region made of a first material with first physical properties, and wherein the at least one first region has a functional surface, which is in contact with a web- or sheet-shaped substrate and which is subject to wear. The component part provides a solution, by means of which the reaching of degrees of wear or also of wear limits can be easily determined without using aids. The component part is configured such that adjacent to and/or spaced apart from the at least one functional surface, at least one second region is at least partially enclosed by the first region.

PRINTING WITH MEDIA ROLL CHANGES AND NONPRODUCTION FRAMES

In an example of the disclosure, first and second print jobs are received at a printer. The first and second print jobs each include production frames. The first and second print jobs are printed with a media roll change occurring during printing. A first finishing device information nonproduction (“FDIN”) frame and a second FDIN frame are printed. The first and second FDIN frames include coded information regarding the first print job and the second print job, respectively. The coded information is for reading by a scanner at a finishing device. A press calibration nonproduction (“PCN”) frame that includes a printer calibration diagnostic is printed. A scanner at the printer is caused to capture the printer calibration diagnostic. A calibration operation is performed at the printer utilizing data or attributes captured from the printer calibration diagnostic.
