DEK Gray scale for the evaluation of color change DIN EN 20105-A02

This gray scale consists of a series of nine pairs of matt gray plates that have contrast levels from "1" = strong color change to "5" = no color change with the respective half-levels. Each pair of the gray scale corresponds to an authenticity number. By comparing the contrast between the treated and untreated samples with the corresponding levels of the gray scale, it is possible to assess how resistant dyed or printed textiles are to the influences to which they are exposed during production or use. This is the short version. It can be used on both sides. We also sell a long version that is single-sided.
