Problem with Texture Line Style applied to a donut shape.

[Rett]

So I created a logo in Affinity Designer using a donut shape to make a letter "C" outline. I applied a "Texture Line Style" using a brush and it looks nice. 

 

I exported it to pdf and sent it to a vinyl sticker printing company to print the logo onto a clear sticker. When they printed the logo, there was a strange outline to the whole thing. Upon closer inspection, it appears that the vector donut shape is still visible behind the texture line brush for some reason. You can see it zoomed in:

I have tried everything and I can't do anything to make that outline invisible. Any help with this?

 

Thank you!

Also here is the design file in case anyone wants to try things with it!

The layers have a brush which is not fully transparent. I boosted the transparency to make this visible. 
The area matches the stroke width.

I assume you export as raster format (flattened). Then you can add 1-2 adjustment layers to truncate alpha values below a threshold, e.g. 10%

Another non-destructive possibilty is to group (blue) the Outer C donut objects (green) while making a copy of one donut (red), giving it a simple solid opaque stroke, and adjusting its width and angle and mask the blue group with it:

If the export should be more "vector", then you may want to expand the stroke mask to regular curves so that the mask remains a vector curve. Otherwise masking with a stroke will rasterize.

Wow thank you! Truthfully I don't even know what you did haha! But it definitely looks better. For some reason I still don't understand why the donut shape is visible instead of only the texture line. But this looks really good, so thank you.
