   Hi
   I'm trying to print a sheet of clear acrylic with a white layer at the bottom, and for some reason, a cloudy print is appearing. I don't know if the same thing is happening in colored substrates, because I can't see anything at all of this, maybe because they are not clear, or are not noticeable. I'm attaching a photo where you can see what I'm talking about. I'd like to get some ideas about what's happening and how to fix it.

   I don't know anything about that particular printer, but that looks like ink vapor deposition. On our printers, that can happen with too-low humidity in the room, or excess static electricity in the substrate.
