Abstract:
1. A printing system comprising: a first unit that obtains a rendering command specifying a combination of at least a thickness and a color of a line; a second unit that converts the rendering command into a converted rendering command by converting the combination specified in the rendering command so that an average darkness of a result of printing the line matches a desired average darkness of a result of printing the line using a target printer; a third unit that generates image data including the rendered line based on the converted rendering command; and a printing unit that executes printing based on the image data, wherein a pattern image is printed by the printing unit which indicates a plurality of average darkness values as a combination of each of a plurality of different thickness and colors of a plurality of lines, the pattern image being used to establish a correspondence between the plurality of average darkness values of the printing unit with a plurality of target average darkness values of a target printer, and wherein the second unit converts the rendering command specifying the combination into the converted rendering command; wherein the pattern image is printed by the target unit to obtain the plurality of target average darkness values as a combination of a plurality of different target thickness and target colors of a plurality of lines.
