Abstract (en)

[origin: US2013107291A1] A method and apparatus are provided for providing color consistency on a same digital printing device at different points in time or on multiple digital printing devices. Measured spectral color values, which correspond to a particular calibration set of a printer-ink/toner-media combination, are stored as target values. Spectral color values are measured subsequently for the same printer or for other printers and compared to the target values to determine whether the output data of both printers will be consistent. Optimization processes may be performed to ensure or improve consistency.
