Colorimetry
Print the chart for colorimetry on the printer to be adjusted for colors, and scan
the chart on the machine to measure its colors.
You can select a chart from the list of charts for colorimetry that are commonly used, but you can also specify the paper size and color boxes to create a new chart for colorimetry. Save the measurement result in IT8 or CGATS TXT format. Load this file in a color management app or other application, and use it to manage the color quality of a printer.
