improving performance of rear projection setup

[frank.leggett]

Hi

I did a test today using a 4000 ansi projection housed in a 8ft x 8ft x 8ft wooden cube which we covered the 3 internal sides with thin black cloth to improve the brightness of the picture. This worked out fine but the client now wants a larger screen (He saw a 8ft x 6ft demo) and he now wants a 10ft by 7½ft. I was wondering if anyone out there had experimented with different ways to black out the interior of the cabinet to improve the performance of their projectors. I still have the roof and and floor that can be either painted black or clothed and I've considered using black floor tiles. Any ideas?

Never tried it myself but cant you just use Chalk board paint. Its matt black so shouldnt reflect much light. To get a smooth finish you could use a gloss roller.
