Abstract: An inkjet printing system including a media source supplying sheets of transparent film. An image processing module receives and converts input image data to output image data comprising a plurality of output pixels configured to select an ink profile. Predetermined ink profiles are selected representative of a series of test patches each having an expected density. A printhead is configured to eject droplets of available colors of ink onto a sheet of transparent film based on the selected ink profiles to produce the output pixels and an output image thereon, including the series of test patches. A transmissive densitometer measures the actual density value of each of the test patches, wherein the image processing module adjusts the output pixel values based on a deviations between the expected and actual density values of the series of test patches.

Abstract: A method and apparatus to improve toner drying on electrostatic printing media is disclosed. A drying apparatus placed between two print stations in a single pass electrostatic printer provides air from two different drying assemblies, one adjacent to one print station and a second adjacent to a second print station.
