Abstract: A deposition module within a web press for inhibiting media deformation may include a fluid deposition device located on a side of a media, and a processing device to control the fluid deposition device to selectively apply a wetting agent to the media. The deposition of the wetting agent may be based on the location of content printed on the media as defined by print data.

Abstract: In an example, an apparatus is described that includes a first print section, a second print section, a dryer, and a printing path. The first print section includes a first fluid ejection array, while the second print section includes a second fluid ejection array. The dryer is positioned adjacent to the first print section and the second print section. The printing path that travels in a first direction through the dryer after exiting the first print section and travels in a second direction through the dryer after exiting the second print section.

Abstract: In one example, an aerosol control system for a printer includes an air knife to discharge a sheet of air into a flow of aerosol along a moving print substrate web and a vacuum near the air knife to suck up aerosol from the flow simultaneously with the air knife discharging air into the flow.

Abstract: A drying apparatus usable with a printing system includes a housing, a first set of radiative heating elements, a second set of radiative heating elements, and an air handling device. The housing includes a front region and a rear region adjacent to the front region. The front region includes an inlet to receive media. The rear region includes an outlet to pass media there through. The first set of radiative heating elements is disposed within the front region to heat the media. The second set of radiative heating elements is disposed within the rear region to heat the media. The air handling device is disposed across from the second set of radiative heating elements to jet air within the rear region to cool the media prior to the media being passed through the outlet.

Abstract: In an example implementation, a processor-readable medium stores code representing instructions that when executed by a processor cause the processor to initiate motion of a media web in an inkjet web press, begin printing a print frame based on a start pulse from a metering device, verify that printing the print frame is complete, receive a signal from the metering device that a frame-length of the media web has been measured at the output of the press, and begin printing a new print frame based on the verification and the signal.

Abstract: Provided in one example is a method. The method includes generating, using a processor, data of a negative of an image to be printed on a print medium. The method includes determining, using the processor, a moisture profile of a print job, which print job includes the image and the negative, using data of the image and the data of the negative. The method includes generating, using the processor, printing instructions of the print job using at least the determined moisture profile. The method includes printing the print job on the print medium using at least the printing instructions.
