• extracting first and second data from a sortation instruction, wherein the first data and the second data jointly identify one shipping resource of the plurality of shipping resources;
• selecting one region of the three or more predefined region based on the first data;
• selecting a symbol or pattern based on the second data;
• and
• printing the selected symbol or pattern on the selected region of the sortation label by activating the coloring agent of the selected region.
