    Abstract: A system and method are provided for implementing a process by which printed rolls of substrate material web have additional material layers interleaved between the rolled material web layers to substantially eliminate back transfer or roll offset of printed images on the back sides of the rolled material substrates. In a process for pre-printing thermoforming grade plastic materials to produce rolls of substrate material for use in a thermoforming process, ink compositions, particularly adapted for the thermoforming process, are deposited on substantially continuous webs of substrate material. The webs of substrate material are then re-rolled with separate layers of low surface energy substrate material interleaved between the layers of the printed substrate material in order to substantially eliminate imaging defects produced by back transfer of printed images on to the backs of layers of the printed substrate material stored in rolls.

    Abstract: A system for printing at least one stretchable ink on a thermoformable substrate having a first surface and a second surface opposite the first surface, the system including an unwinder arranged to feed the thermoformable substrate from a first roll into a web drive subsystem, a surface energy modification device arranged to alter a substrate surface energy of the first surface to enhance wetting and adhesion of the at least one stretchable ink to the thermoformable substrate, at least one first full width printhead array arranged to deposit a first portion of the at least one stretchable ink on the first surface of the thermoformable substrate, at least one second full width printhead array arranged to deposit a second portion of the at least one stretchable ink on the first surface of the thermoformable substrate, at least one radiation pinning device positioned proximate the second surface and arranged to partially cure the first portion of the at least one stretchable ink on the thermoformable substrate prior to the second portion of the at least one stretchable ink being deposited on the thermoformable substrate, at least one radiation curing device arranged to cure the at least one stretchable ink on the thermoformable substrate, a full width array sensor arranged to monitor the at least one stretchable ink on the thermoformable substrate, and a rewinder arranged to receive the thermoformable substrate and to form the thermoformable substrate into a second roll.

    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 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.
