I am using Adobe PDF Print function/Properties to embed fonts in the PDF file since the publishing company I am working with demands it. The original file is 6x9. After I embed fonts, the size changes to 6.38x9.01, which is unacceptable to the publishing company and kicks it out with an "invalid trim size" error.
Does anyone have any idea why this is happening?
Are you creating a new PDF file from an application or are you trying to embed fonts into an existing PDF file.
When you say that the trim box changes, it seems to imply that you are creating a new PDF file from an existing PDF file by printing from Acrobat. That is a process known in the industry as “refrying a PDF file” and typically causes more damage that anything those who advocate this particular hack may possibly gain.
If you have a PDF file that needs to have fonts embedded that currently aren't embedded, assuming you have Acrobat Pro, you can use the Acrobat Preflight fixup function to Embed all fonts to perform this function. Of course, those fonts must be installed on your system.
If the “colour version went all strange” it would be indicative of a faulty PDF file to start with.
If the “author” is providing PDF files to you that were exported from InDesign, those PDF files should already have the fonts embedded. In fact, it is very difficult to export PDF from InDesign without embedding the fonts. Perhaps if you could post one of these file (prior to embedding the fonts via Preflight), we might be better able to diagnose what's going on.
How do I attach a file? I see only a URL link function.
It's 377 pages. I can provide you with one page - the original and the result. Will that work?
Okay - I think I solved the issue. I split the file in half, ran Preflight on both halves to embed fonts, then combined them again into one file. That worked. Must be related to file size. The book is 377 pages.
If you must edit the PDF in Acrobat, you can go to Tools> Edit PDF> Select all> and drag everything to the right or left. You can turn on the rulers and guides to help keep the changes consistent page to page. A much better way would be to download a free trial of InDesign, although there is a steep learning curve. I would ask for a packaged InDesign file and make the changes there, then export to a new PDF. If you can only get a PDF (make sure it's a high-res print PDF and not a low-res proof PDF), place the PDF into a new InDesign file, make the position adjustments and export to a new PDF. You might consider finding an InDesign user who is willing to do the work for you for a small fee. You can check the original PDF for properly embedded fonts in Acrobat- File> Properties> Fonts they should all say embedded or embedded subset.
