Need Help Ghosting only summer on specific fabric.

Hi,

In this summer, we have a lot humidity ( 50-60% ) and on certain fabric (polyester look like coton), i have a ghost on the first 5-6 inches. After one pass, i flip for sublimed the other side and now, no ghosting and very sharp transfert (sub). I use Monti 853 calendar. I print on paper before and use tack paper, not direct on garment. My print paper before is always dry since two or threee days.

I don't have this issue with other else fabrics, and in winter since many years, no ghosting too.
