Abstract
A method, system and apparatus for rendering a gloss effect on a recording medium, can involve rendering a foreground pattern using a first ink composition comprising infrared absorbing colors, wherein said first ink is lightened with lightening parameters by the addition of paper white holes and rendering a background pattern using a second ink composition comprising a process or spot color, wherein said second ink is darkened with darkening parameters by the addition of infrared absorbing colors that have different amounts of infrared absorbing colors than that of the first ink composition. The lightening parameters and the darkening parameters are adjustable to ensure that the first and second inks appear approximately the same at printed sizes. Anisotropic properties can be introduced to the first and second inks, causing non-uniformity in their reflection of light in different directions when viewed under a light source, thereby creating a gloss effect renderable on a recording medium. An infrared (IR) signal can be embedded within the gloss effect to enable detection of the gloss effect using an IR sensor or an IR device.
