A surface has to refract light in a certain way.
Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated. Common examples include the reflection of light, sound and water waves. The law of reflection says that for specular reflection the angle at which the wave is incident on the surface equals the angle at which it is reflected. Mirrors exhibit specular reflection.
A sheet of paper simply isn't shiny or smooth enough. It may seem quite smooth, but actually the particles are quite rougher than the particles of a mirror, for example. Obviously, it isn't a very shiny material.
If the surface is shiny then you might get an image on a screen. If the surface is transparent as well then refraction well also take place.

try to make it smooth as much as you can either by rubbing it or by polishing it......
Shiny aluminum foil.

It goes shiny and smooth.
use conditioner, it's gonna make your hairs shiny and smooth.
this happens because the coating is smooth on the clear spoon but is not clear on the fuzzy spoon.
It isn't.... take water for example it isn't "smooth" or "shiny" but has reflective properties
