Gargantuan files - Still not solved with latest 28.7.1

Question

To AI software development team, and to all users experiencing similar frustration ..Let me preface with AI has been my GO-TO for all my design files for the past twenty years. Posters, magazine, flyers, social graphics.. you name it. However it never ceases to amaze me that I can create a 626k file, prepare the file for print, and it balloons to 626MB ?!?!?!?! Yes, I've read ALL the technotes here – restart AI, delete prefs, embed your fonts, don't create outlines, etc. Mind you if you're asking someone to NOT create outlines for fonts is a non-starter. Many times bitten, and always shy – no matter how I save the PDF with fonts the printer always calls back asking for the fonts. YOU HAVE TO create outlines to have a successful print file. This has been 100% successful print results for me.That said, the AI wizard developers can't solve how a file can go from 626k to 626 megabytes ?! Boggles the mind.Before you ask me what kind of design files these are - Just for ie simple 24x36 vector design posters. One poster has a 30 word count body text. The others big headlines, some color gradients. Nothing fancy. No embedded jpg or png images. All vector. All simple.Consider this part rant, part love for the program. This frustration continues with the latest update - 28.7.1. Thanks for reading. And oh, open to any other solutions to solve this issue.

Earlier you mentioned everything in the poster designs was vector-based. JPEG and PNG images are not vector-based elements; they are pixel-based. Additionally, if you are saving a PDF file of the layout and with no data compression applied then those embedded JPEG and PNG images will be saved as if they're no different than an uncompressed TIFF image. They'll be saved at the maximum file size. Depending on how many pixels each raster-based logo has will mean that much more data used up on the hard disc.

I get that. My bad for not being more clear in the beginning on the AI file contents. Bottom line is those jpg and png images were abt 500k each embedded into the PDF.

Regardless I think I've settled on a solution for now – Just to make sure to uncheck that Preserve Illustrator Editing Capabilities box when exporting the PDF for print.

What is the document raster effects setting for your 24x36 poster designs? If it is set at the 300ppi default then that may be one culprit for the large file sizes. Does any of the vector elements have any live raster-based effects such as drop-shadows, glows, etc? I typically use lower resolution raster effects settings when designing large format projects at full size. IMHO, 133ppi-150ppi is good enough for a one-sheet poster. 72ppi is good enough for a vehicle wrap. 25ppi works just fine for billboard faces.

Fonts normally should have no problem embedding in a PDF that is ready for print. A print shop should not need the fonts in order to print the job, if they have a proper setup that is able to handle Adobe PDF files natively. With what I've paid out of pocket for certain type families I certainly don't like the idea of giving a third party outfit "free" copies of those fonts. I'd rather convert live type objects to outlines too.
