I have an artwork with one Pantone colour and I need to export it to PDF with Press Quality. In "Save Adobe PDF" window in section "Output" is it correct to choose "No conversion" in order to export it with correct Pantone colour information?
As far as my experience when I export a PDF and choose press quality illustrator keeps colours as pantones if they were set as such.
This is what the output looks like when I export my artwork
When I re-open the PDF with illustrator Pantones are still there.
