Exporting large scale for print - 3 separate slices

Question

Hello,I have a client request for a print of one image in 3 slices.  Original photo was upscaled to 16926 x 11284.Final dimension of photo should be 97x236 cm per slice (291x236 cm in total).I didn't add bleed, but each side is about 2 cm larger (will be covered by frame). It needs to be exported as PDF. I put the photo in PS and dragged it to fit the frame, used View-Guide-New Guide Layout and made 3 slices. Since Save for web is not an option in this case, I've created another background/separate file with dimension 97x236 cm and copied the sliced layers to it separately and exported as PDF.  Is this a correct way to do it or is there any other better way? Thanks!

Whatever works is the "correct" solution.

You can use canvas size to "crop" each section and adjust the anchor point. Then save a copy and revert and repeat. Or the crop tool rather than canvas size.

Or a script to automate the creation of separate image "tiles":
