PDF photo-color issue

[toonybrain]

I just downloaded Affinity Publisher BETA; it was previously unknown to me. So, it's my first day with it.  I'm not yet as savvy as some of you, but I did use Serif's previous publisher software (PagePlus X8), so I image my transition should be somewhat easy. Serif does makes intuitive products.

First thing I did was I opened a pdf book proof to see if it would have editability in AP. Some of the illustrations opened in full RGB color, but some opened as "negatives." I closed the file, then reopened it - same thing. I closed AP, then reopened it - same thing.

Bug, or me?

Hi Toonybrain

It's not just you it's something we are trying to track down but it does seem to be something in images for documents that start as PDFs. Are you able to provide the PDf you started with at all? I can provide a link to upload to if this is required

Thanks

Thanks, Chris, for your quick response.

I can certainly upload the pdf. May I send it to you confidentially because it's a book proof?

I'm almost certain that the original PDF was created in Adobe InDesign, if that helps.

Chris_K, 

I have had also inverted colours within a document (1 page out of 20 is wrong and cannot be INVERTED).  Issue with 139, 145 and 162

See my comments in "Negative images when exporting to PDF"  by richardlockton. 

In attachment:  single page original PDF file, Afpub file and various wrong PDF outputs created by Publisher

Process: create a white page and use the PLACE fonction to position a single page PDF. Do this 20 times. 

Work around was to restart the whole document from scratch and PLACE differently the PDF.

By the way, you will see that the .afpub files created by Publisher are huge compared to the sum of the original PDF. PDF files created by Pubisher are OK in terms of size.

Note: all original single PDF pages were scanned with Vuescan and cleaned using Affinity Photo. Then resized with bleeds of 2 mm with Foxit Phantom Pro (which is part of my present workflow for managing PDF X/3 prints) Foxit was used as at the time there were issues with Publisher bleeds management

The problem is still there with 174.

Please note that Publisher displays the correct colour when you open the .afpub file, but all PDF exports fail to show page 4 correctly

The problem is still there with 192.

Additional note: the preview of the page shows correct colours. Colour inversion happens only with page 4 either in the PDF of the whole document or in the single page 4 save.
