So i have an issue with vectors. Since i want to reduce the size of final pdf and there's no option rasterizing it while exporting it I was forced to ask for your help guys. So I have a indesign file with approximately 80 pages containing pictures and texts as well as some vector drawings, i.e. autocadexports as pdf. I'd like to rasterize these pdfs in order to achive smaller output but to keep some decent quality, when not high. I tried to export everything first as jpeg and then place thoes in new file, but result was lowquality and big size. I also tried to flatten pdf by adjusting the opacity of pdf on 99,9%, bud result is the bad quality of export as well as bad text. Do you have some tips or tricks for methe? Im on the edge of nerve breakdown. Tnx in advance

    You can force all vectors to rasterize by exporting a flattened PDF (PDF/X-1a or Acrobat 4 Compatibility). If there's a transparent object anywhere on the spread the Transparency Flattener preset determines how vectors are exported:

    So you can set the Raster/Vector Balance to all Rasters and choose a line art resolution.

    Here I have a transparent rectangle on the page which will force the red circle to rasterize. The transparent object can be anywhere on the spread and doesn't have to touch the vector objects. Set the custom flattener preset in the Advanced tab

    You can see the red circle has been rasterized

    The same page to PDF/X-4

    Hi Kolya,

    to reduce the final size (and not rasterizing), try to open the pdf in Acrobat pro and save it optimizing, see here:

    Hm, I don't think that "optimizing" will do much on vector artwork.

    However, it deletes all unnecessary data and items, reducing the size of the file

    Hi Kolya,

    you could open the PDFs of your autocad exports with PhotoShop at your preferred ppi value.

    Depending on the scale you are using them in your layout you could do them as 1200ppi effective ppi.
