Abstract: A system for printing at least one stretchable ink on a thermoformable substrate including a first surface and a second surface opposite the first surface. The system includes an unwinder, a printing module and a rewinder. The unwinder is arranged to feed the thermoformable substrate from a first roll into a printing module. The printing module includes a flood coater arranged to deposit a coating layer on the first surface of the thermoformable substrate.

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 direct-to-object printer includes an ultraviolet (UV) curing verification subsystem. The verification subsystem includes a ribbon that frictionally engages an image on an object that contains UV curable material. An imaging device generates image data of the ribbon that engaged the image and the image data is processed to determine whether any uncured UV material is present on the ribbon.

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 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 direct-to-object printer includes a plurality of imaging devices that generates image data of an object secured in a holder before the holder and the object pass a plurality of printheads for printing an ink image on the object. A controller receives the image data and converts it to an object profile. The controller operates ejectors in the printheads with reference to the object profile to attenuate inconsistent ink image density and ink image distortion.
