Abstract (en)

[origin: WO2020093080A1] The invention relates to a method for producing a security feature (1) in the form of a color image (2), wherein: in order to produce the image, a colorant is applied to a substrate (3); the image (2) is divided into grid areas; grid areas (4, 5, 6, 9, 10, 11) of the image (2) that are directly adjacent to one another partially overlap; a region of overlap (7, 8) of directly adjacent grid areas (4, 5, 6, 9, 10, 11) is smaller than one of the grid areas (4, 5, 6, 9, 10, 11); each grid area (4, 5, 6, 9, 10, 11) of the image (2) is assigned at least one color and at least the regions of the substrate (3) corresponding to the respective grid areas (4, 5, 6, 9, 10, 11) minus the corresponding regions of overlap (7, 8) are each covered with at least one colorant of the particular assigned color; the regions of overlap (7, 8) between adjacent grid areas (4, 5, 6, 9, 10, 11) are covered at least with the colorant that has the color that is assigned to one of the grid areas (4, 5, 6, 9, 10, 11) overlapping in the region of overlap (7, 8) in question.
