    摘要： The invention concerns a method for producing a luminescent pattern comprising the following steps: breaking down the pattern in accordance with a raster (2) comprising a series of non-overlapping cells (3); for each cell, determining from at least two luminescent materials emitting radiation at different colours when excited, a luminescent material dot having dimensions at most equal to the cell, and an appropriate colour such that one combination of different types of radiation of adjacent points recreate a corresponding zone of the pattern; printing the dots (4) thus determined in the corresponding cells of the raster. The invention also concerns a luminescent pattern comprising a series of non-overlapping dots of at least two luminescent materials emitting different colours when excited, at least one part of the dots emitting colours combining to produce at least a third colour.

    摘要： The invention relates to a method of printing an image from a source image comprising the steps of: defining an order of juxtaposition of the ink dots in cells of the image as well as an orientation of said ink dots in said cells, the cells having identical dimensions so that each cell can comprise a dot of each of the inks used, the various dots being juxtaposed, calculating (102) a number of said printable cells in the image, redimensioning (103) the source image whose number of pixels corresponds to the number of cells in the final image, performing (104) a stochastic screening by thresholding, with the aid of the screened image, generating (105) a utilisable file by drawing, for each individual cell of the utilisable file, dots of each of the inks used. The invention also relates to a security document and a substrate comprising an image printed by such a method.
