Abstract
The invention relates to a method for printing one or more security items (10) on a substrate of which at least a part is made of a transparent material, wherein the method comprises the steps of
- printing a first pattern of indicia (1) in at least two colours (Y, M, C) on one side of the said transparent material, this first pattern of indicia (1) being provided such that a partitive mixing of colours occurs between the colours (Y, M, C) of these indicia of the first pattern (1);
- printing a second pattern of indicia (2) on the opposite side of the said transparent material, such that particular indicia of the first pattern (1) are at least partially overlapped by the indicia of the second pattern (2);
- the overlapping indicia of the second pattern (2) having a filtering or masking function with relation to the overlapped indicia of the first pattern (1) such that, because of the parallax effect due to the thickness of the substrate, the partitive colour mixing of the indicia of the first pattern (1) changes with a changing angle of view resulting in a change of the overall colour of the indicia. The invention furthermore relates to a security item (10) printed on a security document according to such a method.
