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.

Method and apparatus for controlling the color accuracy of digital printing devices and adaptation to a previously defined state

An inkjet printer is placed in communications with a print production planning and scheduling system to allow planning, monitoring, and adjusting of an automatic digital (ink jet) printing production line. In one embodiment, the order of the print jobs is defined by the print shop owner or by the associated supervisor. Each job becomes a paper based (printed) job ticket and the order in which the jobs arrive at the print operator side defines the print order. The same is true for the order at the RIP side. Any change in regards to this order requires a direct communication of the print shop owner or supervisor with the printer or RIP operator.
