Abstract: This procedure consists in a first stage of reception of the information given by a client and its technical analysis. It also consists in a second stage of preparation of photochromes and flat colors on the basis of the “Pantone” scale and the CMYK part of the original file. It consists in a third stage of transfer from the “Pantone” scale to an own scale and obtaining the flat colors with this scale. It consists in a fourth stage of reproduction and correction of the color and of the tone scale up to a 97% of approximation, and a fifth stage of calibration by software and manual retouching of these colors and the tone scale up to a 99% of approximation. Finally, this procedure consists in a sixth stage of preparation of the engraving final images in the printing cylinder and storage in an adequate medium. The third stage includes three steps. The first one is the selection of those colors that are nearer to the original.
