Abstract (en)

[origin: EP1184176A2] The correction process comprises reporting the color ration of the printer of the multicolor press by means of test forms. The color irregularities on the test forms are transferred to the pre-printing stage. From this, the raster tone values of the printing form are modified to eliminated irregularities locally dependent on the point of printing on the printing form or film.
