Question about UV Layout export

Hello Blender community!

I’m a rookie when it comes to blender, and I couldn’t find the answer to my issue anywhere. So if this sounds too stupid, please, bear with me.

When I export the layout, the lines separating the faces are antialised, making it hard for me to understand where one face ends and another begins when I attempt to edit the texture in GIMP. My model is a spaceship, and I need precision when making the texture.

So, is there a way to make the lines 1 pixel wide when exporting the UV Layout to a .png? Or maybe, a different way of approaching this?

Thanks for your time!
