It is a common fallacy that you should outline the text you want cut in vinyl.
Spec-ing white vinyl is no different than spec-ing a white ink or varnish layer in print. It should be a solid shape.
The first thing I need to determine when I see an outlined text is to determine if the designer intended me to cut the outline rather than the solid letter. If you apply anything over a 1pt stroke on that text, you will get a phone call asking your intent. (unless you sent a hardcopy of what you wanted.)
The very next thing I’m going to do is solid fill it again. Because I want a solid shape.
My sign software considers stroked shapes as an inside and outside cut (called a “thick line path.”) It’ll give me the option to “weld” it, which increases the outline of your lettering by your stroke width, or to cut as is. But with a 1pt stroke, that is basically a double cut that will often go through a paper backer and ruin my day momentarily. Vinyl plotters can be very stupid sometimes. I try not to make them more stupid by being a stupid operator.
Save yourself the step. Just leave it a solid fill. If you are concerned the sign guy will cut it in the fill color you used, just put a big note in the file “CUT IN GLOSS WHITE VINYL.” Be sure to outline the text in that note too, just so I don’t get a missing font error (when I get that error, I do check for notes, but not everyone will. You might get an intern doing your setup. )
If you can’t communicate with your sign guy…not sure you should be in the communication business. Just sayin’…
