Hello, i've been having this issue for quite some time now. Whenever i place an image into my illustrator file and then rotate it, the ppi changes. It's caused issues with our printing facility as they won't print when the artwork is less than 300ppi. Can someone help me with this issue? I'm attaching screenshots for reference.
I see what you mean, but if I save such a rotated image in a PDF file, Acrobat preflight shows the correct resolution.
It seems to be a bug. If you verify the Dimensions, that values don't change so the resolution is not affected.
"It's caused issues with our printing facility as they won't print when the artwork is less than 300ppi."
Maybe this is a day late and a dollar short.
If you rotate your images in photoshop before placing in illustrator, your ppi will show correctly and problem solved.
Now those pesky print professionals can't bark at your files any longer.
Why not convert to a smart object before saving as well?!
For those of us who live in the real world, these opinions are not terribly helpful...
Please Adobe. Fix this. Or if it's not a bug but instead some kind of "feature" that we just don't understand, then please explain the rationale.
It seems to have been posted to uservoice some time ago, and was listed as 'Added to Backlog' in 2019
Thanks, Doug. Helpful to know that Adobe is at least aware of the issue. You'd think this fixing this particular bug would be a higher priority than it apparently is. I'm not a software developer, but it doesn't seem like it would be a tough fix... it's just math, right?
I can only guess that it's easy to lose track of things that not many people seem to be concerned with. Only eight people including me have voted on the issue. Make sure you vote on it too.
I thought I voted, but I did not, but now I did.
I was told that a bug needs at least 10 votes to be noticed.

If you are submitting a PDF as final artwork, then this will not be an issue. Unless you are downsampling when you make the PDF, the image is still full resolution whether you see it or not in Illustrator (A Preflight in Acrobat will confirm this)
Based on your images, it looks like you might be doing a display panel of some sort (like a pull up banner?). If that's the case, your printer requesting 300dpi is actually waaaaay overkill for that process anyway. If you are giving them a raw Illustrator file with the linked graphics, and they refuse it, they really don't know anything and you should find somewhere else to go. ;).
Another thing to note: Your image is a linked file anyway. Nothing you do in Illustrator is changing the resolution of a separate file.
Hi Roaring Mouse,
With all due respect, the issue raised by the OP has nothing to do with the suitability of 300 dpi resolution... it has to do with AI's failure to properly display the effective resolution after rotation of an image. If you see this for yourself and have the time and inclination to vote for a fix, please do...
Already voted. I was just adding to the reassurances that the OP's file will be fine, despite the bug. Sorry for the editorializing, I was being a bit tongue in cheeky, but my point is, if the printer still brings this up as an issue, the OP might want to point them in the direction of this thread.
It's very annoying indeed, especially considering Indesign does not have this issue within their Links panel. In Indesign Actual and Effective PPI is displayed correctly no matter what transformations you do to it. I see this is a thread from 2020 but it's half way through 2022 now and this still hasn't been fixed. Surely it can't be that difficult, relatively speaking?
Interesting I found this issue more than 10 years ago and it still around...
