I'm creating a PDF for print as a poster. I've tried several times saving my Photoshop PSD image as a PDF yet no matter what options I select (High Quality, X1A, etc. it always downsizes the resolution. I have turned off compression and everything else. I can't figure out why. I've pasted the file info from the "Get Info" option on Mac's Finder. The resolution is 1314x1746 px yet the image is 5475 x 7275px when I look at the PSD file in Photoshop.

file info

    Hi. Welcome to GDSE. What are the compression settings for the PDF export? Do you have downsampling enabled? Have you tried setting it to "Do not downsample"? – Billy Kerr Apr 19 at 22:43
  • Hi Billy, thanks for answering. I have disabled downsampling and have set it to no compression. Today when I tried saving I actually got an error that I didn't before: Could not save a copy as “Yoga Poses poster 24x36.pdf” because the document exceeds the 2.00G limit for saving Photoshop PDF files. See Help topic “Saving and Exporting Images” for more information – bigvibes Apr 21 at 8:53
  • It would seem your poster is way too big. Does it also have multiple layers? Perhaps check the answers given here about what resolution a large format print should be. Also, why switch off compression? It will help keep the file size down. – Billy Kerr Apr 21 at 9:01
