We do some transfer, manly 1 color white for black garment, we use 80 to 120, gentle squeege pressure, 1 stroke always.
Ghosting could be due to moving transfer sheet, too much squeege pressure, possible ink gel temp too low...
For you 2 colors black + white I would have print with 305 - 225 black then 110 white.
If the ink is not design for transfer, then I add very fine powder in it, and still powder the last color with coarser powder.
Last I prefer waterbased for this kind of design, it is more durable transfer with superior wash fastness and greater opacity.
