Abstract
A method, system and printing device for rendering digital color changing inks, can involve configuring a digital ink to appear as one color on a digital screen at one angle and as a different color at a different angle, and rendering the digital ink in a digital document. In an embodiment, a black geometric shape can be created, which can turn off RGB pixels. Single-color lines can be then added to the black geometric shape. The geometric shape can be viewed at different angles to determine one or more working patches. One or more working patches can be then added to the digital document. New Digital color changing inks can be created by taking advantage of the RGB output verses angle curves. The digital inks can appear as one color on a digital screen at one angle and as a different color at a different angle.
