Abstract:
1. A method for producing a multi-coloured sign, pattern, symbol and/or image on a substrate with, arranged thereon, capsules containing colour bodies consisting of dyes or pigments, wherein, under the action of an excitation beam, the colour effect is released, wherein different capsules having at least two different colour effects are arranged on and/or in the substrate, said method comprising the following method steps; as a preliminary step, generating a data set identifying the location of coloured capsules on and/or in the substrate and storing said data set in a database, and thereafter, a producing a colour chart, in which the potential individual colour effect of individual capsules containing individual colour bodies is contained as a function of the spatial coordinates thereof on and/or in the substrate; b spatially resolved radiation, which opens the colour effect of colour bodies just of individual capsules and releases said dyes or pigments by means of an excitation beam, on the basis of the colour chart in order to produce a resultant colour effect of the released dyes or pigments.
