Abstract (en)
[origin: EP0282446A1] To control ink coloration on an intaglio or flexographic printing machine, contrary to previous practice, use is made of a single and specially designed grey field (4) from which, by means of colorimetric acquisition and subsequent non-linear data processing, the actuating variables characteristic of the process (ink, dilution, solvent) are determined as a function of the reference values. <IMAGE>
