Title:
IMAGING APPARATUS AND METHOD OF USING COLORANT DENSITY
Document Type and Number:
WIPO Patent Application WO/2017/099089
Kind Code:
A1
Abstract:
A method for reducing printing defects in inkjet printing includes determining a respective colorant density for each colorant of a plurality of colorants for a region to be printed; determining a colorant dry-time signal strength as a function of a combined colorant density value based on the respective colorant densities of the plurality of colorants for the region to be printed; determining a respective colorant swath contraction strength for each colorant as a function of the respective colorant density; selecting a dry-time threshold which if met by the colorant dry-time signal strength indicates that a dry-time defect may occur; selecting a respective colorant density threshold for each colorant which if met by the respective colorant density indicates a visible swath contraction may occur; and determining a printing action to be taken based on whether the dry-time threshold is met and whether at least one respective colorant density threshold is met.
