Exporting a large AI file to PDF for a print job - running into issues

Firstly, please excuse my ignorance in such things I normally work mainly in Product Design but sometimes I get roped into the more Graphic end of things as I work for a small company. 

 

I've been tasked with creating a design file for an exhibition booth - 5 panels roughly 1x2 metres but was asked to provide the artwork as a PDF at 25% scale. I believe I've managed to get the Illustrator file set up correctly but the trouble now is the file appears to be too large to export to PDF (I have the High Quality Print preset selected just with added trim marks). I tried exporting individual artboards rather than the whole file in one go but that also is not working. The file contains a lot of high-res embedded images so I'm wondering if that could be an issue? And if so how do I optimise images so I can export to PDF but without losing their quality? Or is there something else I need to be doing/checking? Any help from any proper graphic designers would be greatly appreciated!

    First, if you have multiple artboards I would recommend saving each individual art board as its own PDF file. That will cut down on the file size.

     

    Next, what is the resolution level of the embedded images? Depending on the viewing distance the pixel-based imagery may not need to be very high in resolution. Pixel-based imagery on vehicle wraps can be in the range of 72ppi and still look sharp. Photos on printed billboard ads are often as low as 25ppi. If you're using something like 300ppi or greater that's probably going to be overkill unless viewers are getting up close to the printed panels and looking at them for extended amounts of time.

     

    You should check with who is doing the print work, ask them what kind of RIP application is being used and create your PDF files based on what works best for that RIP. I often save PDF files out of Illustrator for large format printing just using the Illustrator Default PDF preset. Even with that preset you can modify things, such as resolution levels of embedded images.

    Hi, I fought this issue for a couple of days and finally I found that it was a overlay with a gradient over a photo the problem. I deleted and then took the photo to photoshop, add the gradient there AND NOT in illustrator and no more error and the export when faster also. Never again overlays of any kind on photos for me in Illustrator. Hope it help someone.

      Thanks for your comment. Facing this issue now too, and my file has layered raster images and lots of large gradients with blending modes. Will be mindful of this going forward, and thinking tif might be the only export solution for these large format prints.

      Thank you both, I lowered the ppi to 150 and used the PDF-X preset rather than High Quality Print and was able to export all 5 artboards into a single PDF file.

        If it is large scale and not intended to be read as a broschure you don't need to have the same resolution as print book/broschure/leaflet as also Bobby mentions. Start from a PDF-X setting and then change the resolution to 150ppi.
