Trying to cut single lines...

[bexhc]

Hi there, I haven't been on here for years but am hoping that someone can help me please!

I use the Silhouette Cameo to cut vinyl for stencils to use for sandblasting glass. What frustrates me is that it seems not matter how thin I make the lines in the image I import from Photoshop the trace always does the cutline either side of my line rather than it just being a single line, does that make any sense at all?! I've attached a picture to illustrate what I mean.

The reason I need a single line is because I don't want any kind of outline when I'm blasting it. In the past I've had to do it in separate coloured layers in Photoshop and then try and vector them in Illustrator so that it works in Silhouette Studio but it takes ages. I'm not sure if any of this is making sense but thank you for paying attention to my ramblings this far!

Many thanks
