It became a problem since 2020 release. Making project with .psd files resulting with the huge .pdf file.
Maybe I explain it with an example:
It seems like a major problem/bug with layered .psd files while exporting.
And it is something I had never seen before 2020 release. All problems that with .psd files started with last year update and before like in CS6 it worked perfectly with any .psd files, and there was no problem with sending such .pdf via email and then everything was printed like it should. Now it is so hard to prepare such even simple project in .pdf to sending.
There can be problems with image files accumulating ancestor metadata, which can get transferred into InDeign file and exported to PDF. Can you share the problem InDesign and PSD files via Dropbox or your CC account?
Maybe I find a clue in metadata.
All .psd files taht cause that problem have in their metadata saved all color swatches from Photoshop palette. But, I don't know when and how even save it in .psd file (I have never seen such option), and don't know how to clean it from file metadata.
Here is a screen from Bridge:
No the problem is with saved ancestor metadata.
Here’s a PSD example with problem metadata, where the Raw Data in Photoshop’s File Info is too large to display:
Sorry for late answer and thanks, because it was about unnecessary metadata, and I solved it without any scripts. I created a new document with exact pixel and dpi dimensions and just drag with shift key all layers from the corrupted (if we could say so). Then just overwrite previous one. It is quite fast solution overall if it concerns only single files not whole batch, so maybe I'll stick with that without scripts.
So once again thanks for information what could be a problem, and I want to ask just if you know what cause it. Just for curious, because I was working with InDesign and Photoshop for over a decade and never had a problem with that. It all starts with the 2020 release.
It’s not a new problem, here is a Photoshop thread from 2017:
You can go at it manually, but I’ve seen cases where the metadata gets transferred into the InDesign file, so you have to find and fix all the placed problem files, and do a Save As out of ID to completely clear the metadata. The script I posted handles all of the document’s placed images and the save as.
Here’s an example where I deleted all of the placed images with excess metadata from a single page ID doc, and the file size is 198MB
