Large .psb file cannot be saved as .pdf file
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??
