Export from publisher to PDF affects images

[Aniek]

Hi,

I have a publisher V2.3 document that I try to export to a PDF for professional printing. But the images keeps being affected like the rendering did not go right.
I've used images that are part of high resolution pdf documents. The Document set-up is in Iso Coated v2 300% (ECI) and export to an high resolution PDF in the same color profile. 
It does not matter which PDF format I use (PDF/X-1a, PDF/X-3, PDF/X-4) also using the document resolution or use 300 dpi settings.

Last times I did this it was also but it got fixed with an update,  and it also did not matter if the import file to Publisher was RGB or not.

Hi @Aniek,

How did you originally extract the images from the high-resolution pdf documents...

It looks as though some of the Tiff files are corrupt in your PDF file... Could you perhaps provide one of the source PDF files that you've used to extract images from so we can take a look?

There is also a known bug in the Affinity apps affecting ISO Coated v2 300% (ECI) discussed here but I'm unsure whether that is having any specific impact on your file. I suspect not so this is more for reference but out of interest, if you change the colour profile of a couple of your Tiff files and update your Affinity Publisher file do you still see the same issue on export to PDF?

hi @Hangman,

at first I've used the pdf later i gave it a cmyk profile in Affinity Photo .
I just take a look to change the colour profile.  At first it seems to work fine if it was a low dpi pdf. But I've tried eurocoated v2 en  coated fogra 39 with 300 dpi, then it  has the same issues as described in my post above.

Hi @Aniek,

Thanks for the file...

Where are storing your files, are they on your Internal Hard Drive, an External Drive or in the Cloud?

I just took some of the images from the file you uploaded and converted them to CMYK Tiff files using ISO Coated v2 300% (ECI) and then added them to a Publisher Document and the exports appear to be fine...

hi @Hangman
Well I thought that's strange. I exported all the pictures now correctly to tiff, cmyk with the color profile ISO coated v2 300% (ECI). Still, with me, the images are damaged when exporting to pdf 1.3 or 1.4. And the whole document is stored on my computers harddrive.

So I started testing the requirements of the printing agency to a pdf and the normal PDF/X-4.
It happens when File settings are checked by "include bleed", and include the bleed checkbox by advanced setting. Also with having the box "allow JPEG compression" unchecked. Which seems strange to me cause there are no jpeg images? And if you have checked the box "include bleed" should that not also be automatically checked by the advanced settings?

Another question, why makes publisher the bleed in pdf 0.1 mm bigger so with a bleed of 3 mm on each side? Your document should be X.60 mm instead of X.61.

Hi @Aniek,

That's very odd...

The exported PDFs I uploaded, including the PDF/X-4 version had both 'Include Bleed' and 'Allow JPEG Compression' checked and didn't cause any corruption issues...

Could you perhaps upload a couple of the Tiff files that you've created, that appear correctly without any obvious corruption (before importing into Publisher) so we can take a look at the Tiff files on their own...

This is a long-standing, known bug with PDF exports...

[Aniek]

Oh i wasn't very clear i see @Hangman
i only checked the box include bleed by advanced and theJPEG Compression was also checked.
But If i checked the box bleed above by the file settings (not advanced) then the images were corrupted and as i left the Jpeg compression box unchecked also corrupted the image.1.tiff1.tif1.tiff

Hi @Aniek,

The 'JPEG Compression' option is checked by default for all the PDF Presets... It's described as follows in the help section "When selected, rasterised design elements will be compressed to decrease exported file size. If this option is off, rasterised design elements will be exported as uncompressed."

Clicking the  'Include Bleed' option acts as a toggle in that whether you check it in the 'File Settings' or 'Advanced Settings' section it will automatically check it in the other section...

I've just exported the file I created by selecting 'Include Bleed' in the 'File Settings' section and I've tested it both with and without 'JPEG Compression' enabled and I'm not experiencing any issues with the exported PDF/X-4 file (or any other PDF versions.

Could you perhaps download the Publisher file I included in the previous post but one, Kaart 23 lttrcntr v2.afpub and test it to see if you see the same issues when exporting?

[Aniek]

hi @Hangman,

That file works good, So i think the biggest problem is the jpeg compression that was unchecked before. Because only then it fails.
These were settings i'd set with the printing company manually, because I could not load their job options like in adobe. So I thought that was well.
And I did not understand the function of the jpeg compression good enough.

Thnx Hangman for helping me out with my issue.

Hi @Aniek,

The JPEG compression really shouldn't make any difference and it certainly shouldn't be causing your Tiff files to corrupt.

Would you be happy to upload your original Publisher file, just the two pages shown in your original post would be fine with the embedded Tiff files so we can test the same source file where you're experiencing the file corruption issue.

[Aniek]

yes sure @Hangman

Hi @Aniek,

Sorry, the Tiff Files are Linked rather than embedded in the file you've kindly uploaded (which is absolutely fine), but could you upload 5.tiif through 12.tiff as well.

[Aniek]

Sure @Hangman,

Hi @Aniek,

Many thanks for the additional files...

I've not been able to replicate the issue using your source files but let me know if I'm doing anything differently to yourself here...

Hi @Hangman,

this happens when i do it

[Hangman]

Hi @Aniek,

I'm wondering whether you may have some disk corruption on your Mac... In the original PDF file you uploaded all 12 images showed problems whereas in your screen recording, only 7 of the 12 images appear to be corrupted.

Out of interest, if you export your PDF file using the same settings to either DropBox or iCloud do you see the same issue?

[Aniek]

Hi @Hangman,

The first message that I've sended was only with pdf's that were imported as they were.
After that I imported them in Photo to make them CMYK (I don't know if I already attached the correct color profile)
After you're good results with setting them to Tiff images, I changed all the pdf's to tiff cmyk with the right color profile.

Maybe that explains going from 12 to 7 corrupted images. But this is still only with jpeg compression checked out. If I do check that box there is no problem anymore.

I exported the pdf to iCloud and the result is the same as exporting it to my computers harddrive.

[Hangman]

Hi @Aniek,

That is really strange... I'm hoping someone else in the forum can also export your file using the same settings to see if they experience the same problem you're seeing as I'm at a slight loss at the moment to the cause since I've thus far not been able to replicate it...

Which version of macOS are you using?

[Aniek]

hi @Hangman,

thnx for the help so far. I was able make an export, so with that i'm very happy.
But indeed to complete the issue, it would be fine to test if someone else is having the same experience on that part.

I am using MacOs Sonoma 14.1.1

Hi @Aniek,

That's great to hear, what did you do to achieve that?

One last thought... if you export pages 4 and 5 in the attached file using the same settings, do you still see the same problem you had before?

hi @Hangman
keep the checkbox with jpeg compression checked.

exporting the 2 other pages does not make a difference

[Hangman]

Hi @Aniek,

That's interesting and thanks for confirming...

There appears to be a very odd issue here that I cannot replicate. The only obvious physical difference is the version of macOS but that really shouldn't make any difference.

Would you be happy to upload the exported PDF from the Pages 4 and 5 spread so I can double-check something?
