Abstract: The disclosure relates to ink compositions for digital printing on an external surface of a plastic article. The ink compositions comprise an ink removal-promoting additive. In some aspects, the ink removal-promoting additive can facilitate the separation or loosening of the image from the external surface of the article when the image is exposed to a liquid-based solution at an elevated temperature. Also disclosed are recyclable plastic articles having an external surface with an image printed thereon using the disclosed ink composition and methods for removing cured ink from a plastic container. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.

Abstract: A method for printing on an article having a non-planar surface in an embodiment includes obtaining coordinates or a geometry for a non-planar surface of an article; determining a tangent orientation for a print head in three dimensions; and using the tangent orientation and positioning the print head relative to the non-planar surface of the article. Embodiments of apparatus for printing on articles having non-planar surfaces are also disclosed.

Abstract: A plastic container includes a medium applied to a portion of the container. A digital image is applied to a portion of the medium, the digital image being comprised of a plurality of ink droplets. Methods for digital printing on a portion of a medium that is applied to a container are also disclosed.

Abstract: A recyclable article having an external surface with an image printed thereon by droplets of ink is provided. The droplets of ink comprise a composition that includes a hydrophilic component.
