How to create pdf from FM12 with CMYK color settings; getting an error

[Guest]

With RGB setting, I am able to create PDF for a document of 750 pages. But, with CMYK setting the Adobe distiller shows the error as below:

%%[ Error: undefined; OffendingCommand: ct_T3HdrDict ]%%

%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%

%%[ Warning: PostScript error. No PDF file produced. ] %%

no pdf gets generated. Why does it happen?

I am using FM12 and document is of 750 pages. The images are done using framemaker tools only.

Please let me know the solutions.

It's possible that there is an issue with a graphic. You should have seen a listing of processed pages prior to the error. The error occurs on the following page of the last page number listed. You can temporarily turn off the graphics in a file (or book) using the <esc> v v shortcut (it's a toggle, so the same sequence will also turn the graphics back on). If a PDF is created when the graphics are off, then this confirms that the problem occurs with a graphic. Try to locate the graphic in the file (as per the displayed pages in the Distiller log) and change its format.
