The bundle contains the “Ugra Light Indicator Card D50 – PVC Substrate” and a pack of “Ugra Light Indicator Strip D50” of 50 pieces each.<\/p>\n
The “Ugra Light Indicator D50” are used to check the conformity of a standard lighting to the standard illuminant D50. The two green print colours of the card form a metameric colour pair (conditionally equal colours). Under standard illuminant D50, the colour patches appear identical. Under any other illuminant, the colour patches appear different. This type of metamerism is called illumination metamerism. The cause is the different light spectrum of the respective illuminants. This way, you can easily recognise non-conforming lighting conditions and will not be fooled during colour matching.<\/p>\n
The stable PVC card (0.5 mm thick) guarantees long-lasting use. It is used in sales talks or in the training area. A descriptive explanation is printed on the back.<\/p>\n
The self-adhesive label (75 x 15 mm) is affixed to a colour-accurate digital proof or printed sheet, e.g. reset sample. When visually inspecting these colour reference proofs, the label can be used to indicate at any time whether the ambient light corresponds to the standard illuminant D50.<\/p>\n
