Preps 5.3.3 and Acrobat Pro 9

[Al Ferrari]

For a long time now I have kept Acrobat Pro 8 installed after I installed Acrobat Pro 9, and generally I try to use 8, simply because that's the application I had used for printing the IT8 target to have Chomix profile my Epson 7880. So Acrobat 9 would only launch if I double clicked a pdf when neither was running. Mac OSX 10.5.8.

That's the background; now comes the problem: I recently started allowing Acrobat 9 to be the working pre press version to do the kind of fixes allowed without additional plugins. Well I started to have problems with Preps accepting the edited pdfs the last few days and have narrowed it down to the Acrobat 9 saving of the edited pdfs. Even just a simple name change without any edits causes Preps 5.3.3 to not accept the pdf.

Simply continuing the pdf editing in Acrobat Pro 8 solves the problem. So Acrobat Pro 9 and Preps 5.3.3 don't play well together. Has anyone else seen this?

Thanks,

Al

reduce the PDF to version to 5. In Acrobat 9 go to Menu Document - Reduce File Size - Acrobat 5.0 and later

I know you said you're not using plugins, but if you happen to have Pitstop there's a preference you can set that will not allow the PDF version to be changed upon saving. Not sure if there's a such a preference in Acrobat.

M@CK,

That worked like a charm!!!

Thank you, thank you, thank you...

Thanks for the reply Dan.

Our trial period for Pitstop ran out and the company is too cheap to go for it.

You can also edit a config file in Preps to get them to work without doing the "Reduce File Size" which degrades the quality.

- In the Preps 5.3.3 default.cfg file, modify:
USE_PPT_PDFLIB:NO
Change to:
USE_PPT_PDFLIB:YES

Hi Joe,

I like that better since I then will not have to process each pdf. But please explain what exactly does that instruct Preps to do? Does that tell Preps to use it's own pdf library? Or does it tell it to use the one coming in with the pdf? I imagine it is the former, but please confirm that.

Also, are there any negative consequences to that change?

I see you had posted about this in September 23, 2009 at http://www.b4print.com/index.php?topic=3903.0, but there is no discussion of any consequences there either.

Again, thanks.

As far as I can tell, the only thing Preps uses its "library" for is if you are running a mixed PS/PDF workflow. The option in Preferences is to tell Preps what to use to convert PDF to PostScript in that instance - do you want it to use Acrobat to convert or Preps' internal PDF-to-PS converter.

Hi Dan,

So are you saying that it does not play a role in a pdf to pdf work flow?

Some from Kodak posted this at the GUA forum once:

Notes found in the Preps 5.3.2 release notes:

By default, the Preps internal converter continues to be used for PDF internal conversion, because testing shows that it handles most PDF files better. The new Acrobat PDF library can optionally be used, particularly for PDF files that contain newer features such as transparency and compressed objects. However, using Acrobat for conversion can cause preview and print performance issues.

If you need to use the Acrobat PDF library, you can set the new USE_PPT_PDFLIB profile option to YES in the default.cfg file.
