In a C# project with PDFsharp (WPF build) I save a PDF document setting. PdfDocument document = new PdfDocument (); document.Options.ColorMode = PdfColorMode.Cmyk; In the document I draw an image stored in another PDF source and a PNG/TIFF image (depends). When I open the saved document in Adobe Bridge it tells me that both color modes CMYK and
This video will show you how to convert a PDF into one colour mode such as RGB or CMYK using Acrobat Pro.

Digital printers use the same CMYK to print as litho does, but it’s true to say that digital printers can convert RGB to CMYK on-the-fly, and some printers can do a better job of it than Photoshop does. But all digital printers are not equal. IMO the HP indigo presses are far superior to the Xerox Igen presses.

Click "File" and then "Open" on the Acrobat menu bar. Browse to and select the RGB-formatted PDF file you want to convert to CMYK color mode and then click the "Open" button in the file browser window. Click "Advanced" on the menu bar, then click "Print Production" and "Preflight." Click the arrow icon next to "PDF Fixups" to expand the list of In general terms the postscript is used with an RGB color space, and a CMYK color space is just a conversion from RGB to CMYK, so in short, RGB is the "default" color space for PS. In postscript you can explicitly call a CMYK conversion with /DeviceCMYK and you can read more about this in any Postscript related doc, for example this pdf. Sometimes the printer will use profiles build in their RIP. They are often set to change CMYK to machine CMYK (for example the machine will add 10% of Cyan so the profile take that 10% from plates). Unfortunately those RIP profiles can ignore strong RGB colors (as they are set to convert only CMYK to CMYK). Con esta herramienta en línea gratuita, puede convertir sus imágenes de RGB al espacio de color CMYK, utilizando un perfil profesional ICC. El tamaño máximo de archivo permitido es 25 MB. Tipos de archivo admitidos: jpg, png, jpeg, tiff, tif, gif. Las imágenes en el formato TIFF, le darán los mejores resultados para la impresión. Once again, we might be able to tell just by comparing it with the Figma design, because we are exporting it as CMYK, the color difference is fairly noticeable; you can see on the right here again we've got the very vibrant red, the RGB sort of red, same with the yellow, you can see on the left or right here the yellow on the left in our Figma

Exporting the ad to PDF/X-1a:2003 solved the problem!!! The X-1a file was approved (no RGB transparency warning) when uploading it to the newspaper, and it looked OK and had transparency. Previously I had exported with "PDF (for print)" and "PDF (for export)", but it keeps RGB in the PDF. Have a great day Wosven!
I use InDesign for a lot of print layout, and often graphics used/supplied (stock, photographs, etc.) are in RGB format. But for print I need these in CMYK format, and since ideas for which graphics to use and layouts change often before finalization I wait until the final OKs are given before converting graphics to CMYK. The way I see this working is through the "Links" tab, although perhaps
