I have a question about drawing. So I do art as a hobby and as business and I know that according to Ayatollah Sistani it is permissible to draw human faces on paper or 2D. However there is a form of printing called Lino/relief and you basically carve out your design on a sheet of rubber like material and ink it and then press it onto a surface like paper, fabric, etc. So is it allowed to carve human faces or anything like that into it to make a design and print onto something?
