Sublimation on ChromaLux panels

[Janisstals]

So we are testing some sublimation on ChromaLux aluminum panels and they look so great, but with one small problem. There are small black print dots on lighter tones.
I have tried different setting and profiles and different images, but can’t seem to eliminate them.

Could that be that we don’t have light inks just CMYK.
The official website for ChromaLux says we need wasach for profiles, could that be the case?
Has anyone done something like this? Some guidelines would be very appreciated.

We are using ergosoft software and printing on epson shurecolor 9300 or Roland txt-640 with cmykOrVi and fluo inks.
