    Abstract: 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.

    Abstract: A system for printing on a multi-dimensional object includes a plurality of print heads, and a printing chase comprising one or more alignment elements configured to provide accurate registration of an object holder (also configured as an object packaging) relative to the print heads. The system further includes an actuator configured to move the printing chase relative to the print heads. The system is configured to receive information corresponding to an alignment element that is employed for positioning the object holder on the printing chase, determine a position a printable area using the retrieved information, receive information relating to print data to be printed on the printable area, use the determined position of the printable area to control a movement of the printing chase relative to the print heads, and operate the print heads to eject marking material onto the printable area to print data on the printable area.

    Abstract: A method for evaluating curing in an ink composition comprises depositing an ink composition on the surface of an object via a direct-to-object inkjet printing system to form a film thereon, the ink composition comprising a photoinitiator capable of initiating a free radical polymerization process in the ink composition upon the absorption of light to cure the deposited film; exposing, in-situ, the deposited film to light generated by a first source of light under conditions which initiate the free radical polymerization process to cure the deposited film; exposing, in-situ, the cured film to light generated by a second source of light under conditions which induce light absorption by unreacted photoinitiator in the cured film; measuring the absorbance of the cured film; and determining a degree of cure in the cured film from the measured absorbance and predetermined calibration data.

    Abstract: A system for printing on a multi-dimensional object includes a plurality of print heads, and a printing chase configured to receive an object holder for an object and provide accurate registration of the object. The system further includes an actuator configured to move the printing chase relative to the print heads. The system is configured to receive information corresponding to an object holder mounted on the printing chase, determine a position of at least one printable area using the retrieved information, receive information relating to print data to be printed on the at least one printable area, use the determined position of the at least one printable area to control a movement of the printing chase relative to the print heads, and operate the print heads to eject marking material onto the at least one printable area to print data on the at least one printable area.
