PDF Previews from Split Curves

So I have the software running now and I’m using print tool to try to preview print outputs on a target TIFF I have. I’m trying various profiles under the QTR section on the print window. In this case I’ve output PDFs instead of prints, because I haven’t installed the inks yet…But unless it’s VERY subtle they all look the same to me. Is this right? Is there a way to preview the image tone rendering prior to print?

In the print tool I have color management off, no ICC selected etc…

Sorry for the newb questions but I’m just getting everything up and running.

Print Tool / Printing to PDF will not show toning or output at all.

It’s all like a darkroom, you gotta test with paper.
