<p>The invention relates to a method for applying colours by subdividing them according to their percentages allocated to each of the printing points which are for example divided centesimally in accordance with a rule which defines the distribution of appropriately superimposed basic colours, thereby creating binaries and blacks according to the subtraction of the percentage of the basic colour most used percentually from the sum of basic colours less used percentually. Thus, the totality of visible colours are optically generated. The background of the surface to be printed is previously analysed and the percentual quantity in each point of the based colours is deducted in the proportion contained in said background. The application of pigments is carried out by addition of a transparent substrate or medium or white until the proportion of each colour is completed. Application to graphic arts and to the computer reproduction of colours.</p> |
