...or even Brushed on, by golly! Eh Bud? http://www.avsforum.com/avs-vb/showthread.php?t=635968


Now days...., for a bit more than Black Out Cloth, you can get 72" tall x 6 Yrd Artist Canvass....that's been pre-primed and made "ultra smooth" for about $140.00.

That's well within reason if compared to any similarly sized "Board Material' of which there is almost nil such available.


Such material could make a 66" x 117" Screen (135" Diagonal) and still have enough left for a 54" x 96" (110" screen)


That's allowing for 3 Inches extra material on the edges all around to accommodate Stretching/Stapling the material onto whatever Frame is made.

Thanks, I figured some people must have tried it. I saw both the primed and unprimed material and both looked pretty cheap.


Do you have any idea if people have done testing (and written about it here or elsewhere) of it's characteristics in a screen-sense, ie color neutrality, gain, AT properties if any, etc? I couldn't find much.


Thanks as always,

Rukus

I'd say few if any have ever used canvass "as is", but to my knowledge few have ever tried using canvass that was already pre-primed and determined to be "ultra-smooth".


Basic assumption would tend to suggest the surface might well be just as good or even possibly better than would be the coated side of any naked Black Out Cloth. But...if it was only "as good as" and "no better than", I could hardly suggest that it would be the preferred material to use over BOC, what with the latter being significantly less expensive per yard.


Rosebrand sells BOC in sizes (widths) that run out to 110" too. 72"s is the limit for such Artist Canvass.


Be advised that BOC is at best .90 gain...and neither BOC or canvass have ANY AT capability whatsoever.


Most likely the Primed Canvass would produce a brighter image "as is" than would the BOC...but that is speculation based on any white primer being more reflective than is the coated surface of BOC. That much is a given proof.


But as I mentioned above, applying a suitable coating to either substrate will drastically improve the equation...be it anything from a known White to a high performance Gray.

MM,


Slightly off topic.....


That Ultrecht material 135" would be decent for someone that wanted to use it outdoors.


What material have you seen, that is one piece that would give a much larger outdoor screen?

This stuff from Rosebrand:
http://www.rosebrand.com/product34/B...-FR.aspx?tid=7


......comes in 110" wide by "whatever" lengths. Subtracting 6" for attachment leaves 104" wide.


A piece cut to 191" (inclu extra 6") would provide for a 212" Diagonal screen


Not big enough?


How about 122" Wide?

With the last stuff, the "Diagonal Image" potential expands out to 237"

MM,


Sweet!!


That is what I was looking for.


Time for a project to get started for this fall.


Any idea how the picture quality will be, compared to lets say, a big old piece of canvas?

Considering that the surface you'd project on would be immeasurably smoother than Canvass, and have significantly higher gain than would Canvass, I'd venture to say.....


.......the difference would be immeasurably significant.
