Re: Help with the Black Widow PFG DIY Projection Screen

Hi. I wanted to try out to paint my screen with AutoAir 4101 and a grey tone.
I tested it with RAL 7038 and the white seems to drift to a yellow or green touch - it's not natural anymore.

This is RAL 7038:

Would RAL 9006 make a better difference, since it's more grey?

Or 7047?

I mixed 400ml color with 100ml AutoAir 4101.

I figured that might be the case. It's ok though, my wife apparently likes the color and wants to use it for the guest bedroom. At least it won't go to waste! Thanks for your help, I'm doing a little bit more research on this site this time!

I'm not sure if this is the right thread, but I happened to find it while looking for why my paint color turned out wrong. I was trying to make the BW paint according to this thread: http://www.hometheatershack.com/foru...ack-widow.html
But after reading through everything, it seems I added the new AAA to Bermuda Beige, and so basically just got a slightly darker beige after adding. I see that you've recommended a different paint for the new stuff, but is there a way to salvage the paint I already have? I'd rather not have to buy everything again, but I understand if it's not fixable. Thanks!

It's tough picking correctly from a paint card posted online. If we had values for them it would be easier. But it does seem to me that there may be a sweet spot for the new AAA. And it appears to be around N8. Given the measure I did here (paying no attention to the luminance values), darker and lighter grays start to drift slightly. Not enough to be a problem but I think we could do better, given time, at the N9 and N6.5 levels.

Given what I know so far of the new AAA, either G or H.
The member PM'ed this question to me and I said to use J, but the more I think about it I believe H might be more appropriate after all. I now forget at what point adding AAA-F to a base paint makes the mix lighter rather than darker.

Hello,
my setup is not based on polarization. It's dolby 3D filters
(I cant post a link but you can go on avs forum search "infitec" key word)
It's color filtering based on dichroic filter and this method works fine without any special screen.
In my case I need only a gray screen with gain (best reflection possible without hot spot) and a paint that I could be rolled. Do you have any advice if black widow is not appropriate?

Thx
OK, since you aren't using a polarized 3D solution then the only thing you must be concerned about is how much light is lost by the infitec system. With most active 3D and polarization systems this amounts to at least a 50% reduction of image brightness and can approach 75%. It looks like the infitec system could retain more image brightness that the other systems, but I found no hard data on this with my search.

Black Widow™ has a measured gain of 0.89 so you are losing only about 10% of image brightness compared to a 1.0 gain screen. I'm not sure what the gain of your screen would be with your custom mix, but if it was greater than about gain 1.2 you would probably see some hot spotting.

Adequate screen brightness is a very subjective thing so ultimately the only real way to find out if a screen mix will work for you is to try it.

That brings us to the current state of Black Widow™; we recently discovered that the manufacturer of the aluminum paint used to make BW™ changed their formulation and that has in turn changed the color of the base paint used to make BW™. We are doing tests to find new base colors, but early testing suggests that almost any neutral gray paint can be used, We suspect this will eventually lead to a series of new BW™ mixes in varying shades of gray from very light to very dark.

People making BW™ from now on must know the batch number of the Auto Air Aluminum-fine they use to make the mix since this will determine what base color to use. The older version of AAA-F must use a base that is a pinkish-beige for it to result in a neutral gray mix. The newer version of AAA-F does not have that limitation.
