To identify the affected color, print three full-page, solid-fill A3 or DLT sheets for each of cyan, magenta, black, and green and three full-page, halftone A3 or DLT sheets for each of cyan, magenta, and yellow.
Because it is difficult to identify white spots on yellow, green is used instead of yellow.
