METHOD FOR PRODUCING A SECURITY FEATURE

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 adja...

Zusammenfassung:	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. L'invention concerne un procédé pour la fabrication d'une caractéristique de sécurité (1) sous la forme d'une image colorée (2), pour la fabrication d'une image, une matière colorante étant appliquée sur un substrat (3), l'image (2) étant divisée en surfaces tramées, des surfaces tramées (4, 5, 6, 9, 10, 11) directement adjacentes de l'image (2) se chevauchant partiellement, une zone de chevauchement (7, 8) de surfaces tramées (4, 5, 6, 9, 10, 11) directement adjacentes étant inférieure à une des surfaces tramées (4, 5, 6, 9, 10, 11), au moins une couleur étant associée à chacune des surfaces tramées (4, 5, 6, 9, 10, 11) de l'image (2) et au moins les zones du substrat (3) correspondant aux surfaces tramées (4, 5, 6, 9, 10, 11) respectives, moins les zones de chevauchement (7, 8) correspondantes, étant couvertes avec au moins une matière colorante de la couleur associée correspondante, les zones de chevauchement (7, 8) entre des surfaces tramées (4, 5, 6, 9, 10, 11) adjacentes étant couvertes au moins par la matière colorante qui présente la couleur qui est associée à une des surfaces tramées (4, 5, 6, 9, 10, 11) se chevauchant dans les zones de chevauchement (7, 8) correspondantes.
