  • Density fluctuation compensation during print head replacement
    Patent number: 10906296
    Abstract: A method compensates for position-dependent density fluctuations of print nozzles in an inkjet printing machine by use of a computer. The computer produces compensation profiles for the position-dependent density fluctuations over all the print heads for all print substrates used, calculates an mean profile from these, and applies the mean profile to compensate for the position-dependent density fluctuations in the inkjet printing machine. When one or more print heads of the inkjet printing machine are replaced, the computer calculates a new compensation profile for only one print substrate. The computer derives a new mean profile from this, and the computer calculates and applies the new mean profile using the old compensation profiles for the remaining print substrates.
