White-balance is improved when printing on colored media, while minimizing the time and use of costly materials required by present approaches. In an embodiment, the typical solid white fill or background layer is altered by including in the white layer one or more of the other colors already available in the printer to shade this layer. Thus, a small amount of cyan, for example, helps balance a pink-ish (red) media; yellow is used for blue media; and magenta is used for green media; as well as combinations thereof. A combination of transparent process inks and opaque white helps to maintain brightness (luminosity).

Multilayer white printing with white-balance

In a multi-layer printer, the base white layer that is applied during printing is modified using the image to be printed. By altering the white layer to reflect the density of the top image, it is easier to reach saturation (density/gamut) without adding large amounts of ink. Thus, such undesirable side effects, such as gloss-banding are avoided.
