DTG semi transparancies

Hello, I would need a script or guide how to fix this issue:

Attached image I would like to print DTG way.
Thats why the semi transparant pixels need to be full colored.
But the problem is that then the image is not the same anymore. Instead of a fade, it will become two full circles.

Is there a solution to make the pixels full, but more distant from each other? Maybe something like cmyk dots? (Print company needs rgb color).

I searched all over the internet but couldnt find any solution to this, only in black and white or with one color with halftones.
