Affinity Publisher / Photo - PDF export with some weird transparency issu

[schlueter-de]

Affinity Publisher V2 2.1.0

Affinity Photo V2 2.1.0

Win10

 

Hi,

i'm curently working on an architectual competition and we used affinity v2 with photo and publisher this time. Today we tried to export the print pdf files. at the review of the pdf file we found some weird graphic issus.

In Publisher it looks like this:

In the PDF it looks likethis:

 

The issue is also visibile in the print. If we print a pdf with a pdf-printer the issue is not visible. and if we export to png, jpg oder tiff the issu is gone too.

 

First i was thinking about a transperency problem. the car is transparent and the the walltexture in the back too. also the car is linked in the afphoto file. When i change the car to a pixel layer the issue is not visible anymore. But i could not find anything related to the wall. the same issue is visibil in the clouds.

Anyone with an idea? Attached some files if you wanna take a look.

kind regards schlueter-de

I am thinking this is due to the way the file is made. There are lots of layers with varying levels of opacity. I did find that the Car is above the Men layer, if I include the car in the Mensch layer then the little block around the car goes away, but there is still a lightening of the bricks.

@Old BruceThanks for u'r reply. I know there are lots of layers with different opacity. Is this some wrong workflow? i like to group things up and then change opacity over the groups and not every layer seperatly. the export is working like a charm if i dont use pdf. Workaround was to export jpg then combine in pdf and optimize.

But i think this is far away of working as intended. I am thankful for any further tips.

Hi @schlueter-de,

I've found the 2 layers causing the problem.  If you edit the linked file called 'AN Ost.afphoto' and find the Layer called 'Auto' and right click and select Rasterise and do the same for the Group called 'Menschen' and then export, it all looks good.

I'm not entirely sure why those 2 layers are a problem but i'll look into this further and get it logged with the Developers if there's a bug here.

Hi @stokerg,

thanks for u'r reply, I could reproduce this. After rasterising the layout auto and menschen the issue on the wall and at the car were gone. The clouds still had that issue. After your tips i tried this: copy of all layers -> rasteries all layers -> merg all layers to one single pixel layer

this worked but are alot steps to handel an export for a quick presentation of our layout. We got 27 .aphoto files in our final layout.

 

Looking forward to hear from you or the developers. 👋

No. If that is the way you want to work (sounds like the way I would too). I was just pointing out that with the limited time I spent looking at the files that was what I found as a possible source of the problem.

Not a criticism of your workflow but a hint for where to look.
