The growth curves of solution time for printing planning problems with 5 partition numbers and 3 stopping point spacings as the ratio of pixel pitch to nozzle pitch increases: (a–c) small value with steps of 1 mm, 4 mm, and 7 mm; (d)-(f) medium value with steps of 1 mm, 4 mm, and 7 mm; (g–i) large value with steps of 1 mm, 4 mm, and 7 mm.
