PDF export and colours - what went wrong?


Recommended Posts

Hi,

 

I have exported a PDF-file with Designer and as you can see in the screenshot the colours look faded. Why?

 

It is a CMYK document and the ISO Coated V2 300% Profile. Export settings are the PDF-X4 preset as you can see in the screenshot, too

 

Thanks!

Your screenshots don't show the document profile.

Which profile have the placed images?

 

The background is not placed it is directly drawn in AD.

 

Document settings see screenshot

I think, there are 2 issues:

• The background image is not opaque but has slight transparent regions.If you place a white rectangle behind it, it will look slightly different, but more, as it will print later on.

• The main problem: Affinity Designer makes heavy mistakes while rendering the document into PDF: The background image is "modified" by using a HSL-layer. This obviously causes mis-rendering during output. If you first rasterize "Hintergrund" and export the PDF after having done this, all seems correct.

Thanks a lot! Curiously I have not tried this bevore while the adjustment layer also makes other problems with pdf export (https://forum.affinity.serif.com/index.php?/topic/20405-ad-pdf-export-and-adjustment-layers/)
