Dear LEMAIRE Baptiste,
The color mapping feature has only ever worked with the OKI 8432 WT (OKI Pro8432 WT).
So it will not work with your OKI 711 WT (OKI 7411WT).
Furthermore the color mapping feature has been removed from the FOREVER TransferRIP software from version 2.4. onwards.
Hope this could answer your questions
