White space / border on PDF export - Affinity Designer 2

[Beck]

Hey all! 
For some reason for some projects when i export PDF a white line shows along the border of some of the sides. 

I've attached an example.

A white line is showing on the left side border of this design: 

Which is not in the design: 

 

I've checked my "Transform settings" - these don't look out of the ordinary: 

 

I am doing a simple export: FILE > EXPORT > DIGITAL HIGH QUALITY PDF 

Hoping for some feedback if i'm missing anything! 

Ive also attached AF file & PDF file

 

thanks!!

Hi @Beck,

How are you viewing your exported PDF files?

I was going to suggest pixel aligning your 'Back' artboard but I'm not seeing the white line shown in your screengrab.

I am not at all sure what you are after here. The size of the Card is supposed to be 90 x 55 mm but you have included the bleed as part of the document size so they are 92 x 57 mm. Also be aware that PDFs are in points and at 72 pixels per inch so mm and 72 dpi/ppi will result in fractional pixels.

I would make the design at 90 x 55 with a 2 mm bleed and then I don't care that there is a ghosted pixel at the side and or bottom due to misaligned mm versus pixel based work. The Bleed will be trimmed off. Or I would work with pixel dimensions and align to pixels.

Pixels and mm don't work well together.

Hey all, I realised I hadn't replied in here! 
After testing these, some of my artworks had the decimals in under transform which I removed. 

Some of the files also showed white line on certain screens too, so this is all fixed  

 

Thanks for your input everyone!

This problem with the white frame is still not solved. The same thing happens in AF Designer when using "Export persona"
