Interior lighting and illumination systems for aircraft, particularly commercial passenger airplanes. Opposing pairs of LED lamps are positioned in the ceiling panels above the aisles between sets of seats in the passenger cabins. One set of LED lights are directed to illuminate the ceiling panels and may be in a particular color. The other set of LED lights are positioned to shine their lights on storage / stowage bins positioned across the aisles, thus creating a cross-bin lighting system. This enhances the cabin architecture and provides cabin illumination. A reflector can be positioned to direct the light and reduce possible glare to the passengers. The reflector directs the light rays from the LED lights which emanate from the top of the reflector to shine on the lowest part of the bins. The light rays leaving the reflector cross in front of the reflector.

Image quality is improved by adjusting the ejection amount of quality enhancing ink based on the ejection amount of colored ink containing colorant. When a relatively high gross printing medium is used, the quality enhancing ink is ejected in an image area where virtually no colored ink is ejected, thereby improving unevenness in gloss within the print image. When a relatively low gross printing medium is used, on the other hand, the quality enhancing ink is ejected in an image area where the colored ink is ejected on virtually all pixels, thereby improving unevenness in color within the print image. The relationship between the ejection amounts of the quality enhancing ink and the colored ink may be modified by the user.
