ABSTRACT:
Glass screens with different line numbers are used to determine the photoelectric scanning and sampling rates which provide signal samples reliably representative of the density of the off-set image dot structure. Using these rates, the corresponding ink consumption values are determined, totaled over the image, and displayed.
