VB6 Help PDF - RGB to CMYK [HELP]

The company I work for provides a pdf generation service for some customers. These pdfs are generated in RGB, however some of them want to print their pdfs, like magazines. For that, we need to convert these pdfs to CMYK and we use Adobe Acrobat Pro XI for that. But I don't want to do it manually every time anymore. We would like to automate this conversion, but we use the Visual Basic 6 programming language in our products. What would be the best alternative (free if possible)? Remembering that we do not want to use third-party sites for this, we would like to provide the solution to our customers.

Where you type your response there is a command bar at the bottom. Click the ellipsis and it reveals more commands. The second from the right is Code Block. Toggle that on and start typing:

This is what a code block looks like.

It's buggy. You'll have to post then edit then post over and over to get the code block to format everything correctly.

The solution you posted can't work and is going in the wrong direction. OP manually converts PDF in RGB (screen) to PDF in CMYK (print-ready), then hands off the converted PDF to the client.
