I have my map as well as the layout set as CMYK. Colors in my layers are also defined in CMYK. Now I stumpled upon the following issue: When I export a PDF with just a single page, the resulting PDF is in CMYK; as soon as I create a map series, the resulting PDFs are RGB. Is this a bug? Or are there any map-series-specific settings I overlooked?
I'm using ArcGIS Pro 2.3.3.
Thanks and kind regards,
