The bleeding feature will export “extra margins” on your exported file. For example: https://cl.ly/ed4332550067
So I guess your stripes should be like this: https://cl.ly/5da0002e3dae with the strikes “bleeding” outside so when the paper is cut, there will be no white spots on it.
In case you are not sure if the stripes are big enough, you can use the clipping content button to see beyond the canvas. https://cl.ly/fb310fa6209f
