Large .psb file cannot be saved as .pdf file

[Ryukyu]

We have a large banner in Photohop 23.2.2 with dimensions of 24' x 10' (43200px x 18000px) @ 150px/inch.

The file is saved as a .psb.

The printer wants a .pdf file, but we cannot find a way to save/export this file to .pdf.

This is on a Mac Pro with 256 gb of ram, running the latest version of Monterey.

In addition to the layered .psb file, we've flattened it and saved as a .jpg and that still will not save as a .pdf file.

Any ideas??

Consider this. Split the file into two or four pieces and make separate PDF files.

Banner maker should be able to put them back together.

Or reduce the resolution. Clearly they don't expect such a high resolution - way too much for a banner.

Indeed. It's very hard to think of a scenario that requires 43 000 pixels.

For anything like a normal viewing distance for this size, 50 ppi is more than enough (and even that is probably overkill).

So you should be able to just do a save as .. and select PDF but I noticed that was missing?

Try clicking File>Print )or Command+P) to Print....

then in the Print Dialogue Box click "Print Settings"

then click on "PDF" and select "Save as PDF"

that shoud work! Hope it helps!
cheers!
