Abstract (en)
[origin: EP2985150A1] The present invention relates to color correction system and method for correcting color in print jobs run in a printing machine, whereby a first ink unit provides to a printing group of a printing machine an initially mixed ink similar to a target color provided by a prepress digital file. Printing is performed on a support, and an optical sensor obtains colorimetric information about the printed color, which is compared with the target color by means of a control device detecting color deviations in the printed color and calculates the composition of a corrective ink which, when mixed with the initially mixed ink, allows printing colors without color deviations. A second ink unit controlled by the control device provides said corrective ink with temperature and/or viscosity similar to the temperature and/or viscosity of the initially mixed ink used during initial printing.
