There is a difference between zebra banding in gloss versus matte print modes:
Matte print modes which show zebra bands may show slight gloss differences if you look under
an angle over the swaths.
Gloss print modes might additionally show slight color differences over the swaths. For both: the
effects will be reduced when a slower (more passes) print mode will be used.
