Attempts have been made to correct the deviations, for example by changing the layer thickness of the printing inks in the printing process, but that can lead to color deviations in other regions. A gray balance correction method with which wastage that regularly occurs can be reduced and an occurrence of undesired color fluctuations can be avoided, is achieved by using differences between black and chromatic gray areas in gray balance areas to replace the measured values from a first process calibration with corrected measured values and carrying out a new process calibration."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for gray balance correction of a printing process","description":"In printing processes, even when a process calibration under predefined printing conditions is used, it is possible for deviations in the gray balance to occur.
