How can a decorator determine the right photoresist film to use for a sandcarving project?

Photoresist film comes in multiple thicknesses, and which thickness you choose depends on multiple factors:

  • Substrate: The type of material you are sandcarving is one factor in determining what film thickness to use. For example, if you are blasting on tile or stone, you would want to choose a thicker film because you will blast for a longer period of time.
  • Depth: How deep you want to blast also determines what thickness of film to use. If you are just doing a surface etch, you can blast with a thinner film, but if you want to stage-carve, then you want to use a thicker film.
  • Detail: Always remember that you can’t blast a line deeper than it is wide. If your artwork is detailed, you want to use a thinner film. If you use a thicker film, then any lines thinner than the thickness of your film will not show up when you sandcarve. If you want to use a thicker film, then you may need to adjust your artwork to increase the thickness of any lines that are too thin.
