Abstract: 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).

Abstract translation: 在彩色介质上打印时，白平衡得到改善，同时最大限度地减少了现有方法所需的昂贵材料的时间和使用。 在一个实施例中，通过在白色层中包括已经在打印机中可用的一种或多种其它颜色来改变典型的固体白色填充或背景层以遮蔽该层。 因此，例如，少量的青色有助于平衡粉红色（红色）介质; 黄色用于蓝色媒体; 洋红色用于绿色媒体; 以及它们的组合。 透明处理油墨和不透明白色的组合有助于保持亮度（亮度）。

Abstract: Described is a technology for measuring ink film thickness by use of differential lighting between two differently positioned light sources. The technology involves an image capture device, a first set of light emitting diodes (LEDs), and a second set of LEDs, where the image capture device is attached to a printer. The first set of LEDs is positioned in parallel to an image capture axis to illuminate a target object evenly from above with a light perpendicular to the target object (e.g., substrate with deposited ink droplets). The second set of LEDs is positioned to illuminate the target object at an angle, thereby casting a shadow. The image capture device takes two snapshots of the target object, utilizing a different light source (of the two sets of LEDs) for each snapshot. The snapshots are compared to determine the shadow's magnitude and the ink film thickness based on the shadow.
