The invention discloses a light-induced chemiluminescent immunoassay kit and a test method for chloramphenicol (CAP) and belongs to the technical field of light-induced chemiluminescent immunoassay technology. A nontransparent white microporous plate is sequentially added with CAP-OVA coated luminous particles, a CAP standard substance or a sample to be tested, a rabbit anti-CAP antibody and a biotin goat anti-rabbit antibody for reaction without light and then is added with streptavidin-coated light sensitive particles for after-incubation test. The CAP-OVA on the luminous particles and free CAP compete to be connected to the CAP antibody to form a compound body with the biotin goat anti-rabbit antibody and the streptavidin-coated light sensitive particles. Under the excitation of red light, the compound body transfers energy to the luminous particles through the generation and transmission of singlet ionized oxygen for generating fluorescence. A light induced chemiluminescent detector is used to detect the intensity of an optical signal, and the CAP content of the sample can be determined by referring to a standard curve according on the basis that the intensity of the optical signal is in inverse proportion to the CAP concentration of the sample. The method is used for determining the CAP content of foods such as honey, milk and eggs. The kit is simple in structure, short in determination time, high in sensitivity and simple and convenient in operation.

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).
