Hello, I have a friend in the billboard sign business. I was thinking of taking one of his old,white vinyls (I'm pretty sure it's around 10x30 ft) and cut it to size for my screen. whatcha think?

Free, huge, white, seamless material??? Sounds like it's worth a try to me!

I wouldn't be surprised if the vinyl was manufactured with the intention of reflecting as much light as possible... cost effective.

my father ( was in sign bus for years) in law stopped by and the pj was running ( first time he caught it) and he suggested the white reflective scotchbright.

thoughts?

Before he "retired" form the sign bus I was helping him for a couple years, though I know exactly what hes talking about I'll need a sample for POC hey its a DIY idea that needs to be tested.

As I remember it, the Scotchbright stuff is retro-reflective (glass beaded surface). It would be worth checking out, but I would expect it to have a very small viewing cone, kind of like road signs.

white? seamless? 10x30ft? What do I think? I think you should send me what you don't use!

Hi Dangeross

I know it is 4 months old case, But what happened to your experiment ?

I have already tried similar one 6x4 feet is my screen size -
in south part of India we call it " Flexible canvas" used for Digital printing of street banners by printing houses.
It is also white Vinyl material.

Cost was 0.15US$ per Squarefeet - quite cheap for experimenting.

It looks good seemless, white, plain without any logo printing etc etc.. but it has a problem.

1. On one side (this is the side they will digitally print using massive inkjet kind of printers)
it is very smooth and very shiny which reflects the light horribly - not watchable!

2. Other side is relatively not shiny - this is is the side I am using now, but it has a stripped line texture all over it on.
I have a doubt how a light ray will react it on falling on a texture instead of smooth surface.
Anyway Right now I am using it until I get hold of something else.

Somebody who has more experince can say more on this "texture" thing is it good or bad ?

3. And after I project the image on one side ( Mine is a front projection system)
of this material and go around and watch the otherside, I can see the image on the other side also,
I mean to say the light transpasses this material (it is translucent not opague)
Is it the sign of lightgettign lost and it will reduce the brightness (screen gain) ?

Should a screen be fully opague ?

Somebody can help in commenting.....
