Really looking forward to this printer. They did the necessary engineering to make the white ink a profit center instead of a loss. A self-mixing tank with user-replaceable heads is where it's at for white. The Whiteness is very high, visual opacity 91% (L*:4.16 – a:0,48-b:2,34) from the datasheet below. Not like the greyish crap I have dealt with on some machines with a white channel. 3L bulk ink on the 800w
