CMYK Transparency And Spot Color rendering issue
InDesign generated PDF. CMYK output, with transparency and spot colors present in document but not used on the image or background.
Transparent photo x2 over a colored swatch, soft light effect with varying opacity. Acrobat Reader DC on windows does not display properly.
I tried changing settings for overprint and rendering space. Nothing seems to be able to get it to display correctly.
Preview.app, Chrome, Edge, Acrobat Pro, everything else correctly displays the PDF.
