HI, since I'm looking for white substrates for my
DIY Colour Viewing Booth / Light box
http://www.luminous-landscape.com/forum/index.php?topic=58779.0I found nice white laminate film that is very good, the spectral curve is straight, it is more white than i1iO backing.
I simulated different lighting conditions using the i1Share spectral data in Measuretool and the averygraphics seems better.
What do you think?
