• Select "Clear/Special" when using Neon Yellow, Neon Pink, or Invisible Red. Select "Metallic"
when using Gold or Silver.
• When printing on both sides of banner sheets, uneven glossiness is prone to occur because the
temperature of the pressure roller tends to rise due to the long intervals between sheets. This may be
resolved by printing on one side and then manually turning the paper over to print on the reverse
side (manual duplex printing).
• After performing the solution, it is recommended to perform the color calibration of the external
controller.
