Multipass image scans for increased measurement resolution during calibration routines

摘要: Systems and methods are described that facilitate calibrating a print engine using calibration data sets generated at least two different L* levels to provide additional measurement resolution toward the darker end of grayscale spectrum. For instance first, light grey (e.g., 70-90L*) strip is scanned first generate set, second 30-50L*) high 100L*) set. The set used calibrate for values 50-100) low 0-50). Alternatively, single having known value can be once again higher sets, which improve in part
