This will merge all layers into one and remove transparency (filling it with your current background color). You can change the resolution by using the "Print Size" menu under Images.
GIMP 3.0 supports exporting as CMYK in several formats (TIFF, PSD, JPEG, etc). Make sure to check the "Export as CMYK" box in the dialogue when you do, and also export metadata to retain the resolution.
Thank you. The final file must be a PDF. There is a layer filled with the background color. Should each of the half dozen or so layers be flattened, as you suggested? What steps are taken to get the PDF?
