Re:Glossy, MAtte and Dmax- Is it physics?

2005-05-26 by davelongviews

I think the key is that the viewer is seeing the print (paper surface) from a different angle 
than the angle of incident light. Light hitting a mirror-like surface (smooth) reflects at the 
same angle it went in (think of bouncing a ball at an angle to the floor), and none of it 
comes reaches the viewer. In the case of a rough surface the incident light hits the paper 
and bounces back at a range of angles, some of which put the light in the viewer's eyes. 
Again think of bouncing balls on rough surfaces-they go all over the place.

For me it is interesting to contemplate ways of getting around this. Strictly I think there 
are none, but I wonder if in practice there is a solution that amounts to a compromise 
(other than the obvious semi matte). Reflections depend on differences in refractive index 
of the two materials at the interface.
