My printshop operator said something about exporting a PDF where the printer prints B&W pages BW and pages with images (ie colour) in Colour- this can save me large chunks of cash now and in the future as they really gouge you for colour at printshops.
I am taking a leap and assuming it is something to do with CMYK vs RGB as K is definite black as opposed to darkblue or however RGB approximates black.
Does anyone know if LibreOffice can export this way, it seems a real boon for a desktop publisher to have, especially in the academic environment where I am constantly printing out wads and wads of papers and drafts etc, with a few colour coded tables here and there, and yes I know i can separate them, but its really quite a timewaster.
My default settings PDF did not differentiate and I cannot find any specific option in LibreOffice.
I would also be fine using a third party PDF-CMYK tool if anyone knows.
