The tone reproduction curve is adjusted between periodic print-based generations of the tone reproduction curve by: determining the amount of area coverage of marking material applied by the printing apparatus during printing (in subsequent periods following an initial period in which the tone reproduction curve was generated); weighting the amount of area coverage in each of the subsequent periods differently based on how distant each of the subsequent periods is from the initial period to produce a weighted moving average of the area coverages of the marking material; and adjusting the tone reproduction curve based on the weighted moving average of the area coverages of the marking material."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Time and printed image history dependent TRC","description":"A tone reproduction curve for a printing apparatus is periodically generated based on printed items produced by the printing apparatus.
