Abstract: A printer includes an ultraviolet (UV) curing device having UV light emitting diodes (LEDs) to cure UV curable inks ejected onto a surface after the surface travels past a plurality of printheads in the printer. A UV detector having UV sensors is positioned opposite the UV curing device so the UV sensors and UV LEDs are opposite one another in a one-to-one correspondence. A controller operates the UV curing device to direct UV light into the UV detector and receives electrical signals generated by the UV sensors. The controller compares these electrical signals to a predetermined threshold to identify defective LEDs in the UV curing device. The controller then determines how to move the UV curing device across the path of the surface to irradiate areas of the surface previously opposite the defective UV LEDs.

Abstract: A print system and a method for confirming complete curing of a marking material are disclosed. For example, the print system includes a plurality of printheads arranged in a two-dimensional array, a curing light source, a curing confirmation system, a movable member to hold an object and a controller to control movement of the movable member to move the object past the array of printheads, to operate the plurality of printheads to eject the marking material onto the object as the object passes the two-dimensional array of printheads, to operate the curing light source to cure the marking material and to operate the curing confirmation system to confirm that the curing of the marking material is complete.

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 and a fluorophore capable of emitting viscosity-dependent fluorescence upon the absorption of light; 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 the cured film to light generated by a second source of light under conditions which induce fluorescence emission by the fluorophore in the cured film; measuring the fluorescence emission; and determining a degree of cure in the cured film from the measured fluorescence emission and predetermined calibration data.
