Converting an CMYK pdf to single spot pantone colour

[wonderings]

Just convert to grayscale. You can put whatever ink you want in the fountain.

Thats what we do. Its the simplest and fastest way. As long as its one colour on the plate, it doesn't matter what colour it is on the computer. Just make sure your docket or whatever goes with the job lists the correct colour.

I have an existing indesign file of 50 pages + in a single pantone colour and I have a pdf file that is 20 pages + which is in cmyk. I need to convert the cmyk pdf to spot colour pdf to import into the indd file??

Make 'em both grayscale.

Of course, one should be careful to ensure that elements that were solid blacK before the grayscale conversion remain so afterwards.
