Abstract: The present invention relates to the manipulation of differential gloss as may be inherent in halftoned images by utilization of tags. By selectively applying halftones with anisotropic structure characteristics, which are significantly different in orientation while remaining identical in density, as directed by tag settings, a gloss image may be superimposed within an image without the need for special toners or paper. Conventional copier systems will not typically be able to copy such a superimposed gloss image.

Abstract: An ink jet printer includes a printhead and a print medium that move relative to one another in a printing direction. The printhead includes a plurality of ink delivery channels, and an ink outlet corresponding to each of the ink delivery channels. Each ink outlet includes at least two ink orifices offset from one another in a direction transverse to the printing direction, so that as the printhead traverses a print medium, control signals to the printhead can deposit two drops from each delivery channel, which drops are offset in the transverse direction, thereby permitting the use of smaller ink drops and a higher apparent print resolution for the image deposited on the print medium than the resolution of the print control signals in the transverse direction.

Abstract: A user-selectable and/or configurable system/process that ensures the destruction of data files a user wishes to completely erase from a NVM storage medium, such as a hard drive or removable disk.
