White lines appear when rotating seamless pattern

[hkartte]

I've browsed other people's questions with the same/similar issue but still can't seem to get to the bottom of it. Not sure if there's something I'm not getting...

This happens with any pattern I rotate - even 4 vector squares placed together. I like to use vectors for patterns - and I export them as PDF for the type of work I do. When they aren't rotated there aren't any lines when I export, but I sometimes like to rotate them because of the way it looks. But it looks like the pixels aren't opaque. The coverage map doesn't work with vectors when I export them. I don't like to rasterize my vector patterns either.

I tried importing a pre-designed repeat pixel pattern and then adjusted the coverage map accordingly and the white lines disappeared.  

But I like to use vectors - so how do I make my patterns seamless? 

Thank you for your help.

I think this is more to do with antialiasing than actual fault, so it displays these fine lines but if printed they don't show. 

I think this could be tested if a seamless pattern that show lines in Affinity were to be opened in such and Illustrator would the lines still show or would Illustrators display antialiasing do a better job.

That's what I was hoping. I think this is a myth. 

But I was wrong about non-rotating patterns - they have white lines too! Here are some actual printouts.

That is obvious, any chance you can upload the file for us to look at?

Sure. Is there a private link?
