Does anyone know how I can make my ArtRage 4 pieces a higher resolution? For Deviant art and Etsy selling/printing?

Also, When i create a stencil, how come it wont let me use the 'bucket filler' properly? it just fills up the whole page rather than inside of my custom made stencil, yet it works properly for the ArtRage 4 stencils provided.
*i have double checked all my lines and they all connect*
