A wealth of information as always! I'm definitely looking for the darkest paint mix I can get. If you have any tint codes for an N6 or N5 with the AAA included I'll be happy to send you a sample. I an using the new AAA and got the big 32oz bottle (I already went through 4 of the 4oz ones trying out different versions of BW ultra) so I have at least 4 screens worth to experiment with. With the long weekend here in the states I'm hoping to get at least a few test panels done. Any recommendations on the ratios of base pait to AAA? Thanks again for the quick responses!I
The darkest BWU™ mixes we have even minimally tested are made with an N5 base paint. Below are the RGB and LAB values for the mixes. These are even darker than the Stewart FireHawk screens.

N5/AAA-F 4:1 (this has been the standard ratio used for the various BW™ mixes).
RGB 124.3 , 123.5, 123.0
LAB 51.87, 0.26, 0.32 [N5.2]

N5/AAA-F 2:1 (2 parts N5 base to 1 part AAA-F).
RGB 127.4, 126.1, 125.2
LAB 52.93, 0.32, 0.63 [N5.3]

N5/AAA-F 1:1 (equal parts N5 base and AAA-F).
RGB 134.0 , 132.6, 131.1
LAB 55.44, 0.28, 0.92 [N5.5]

I used a quart of Valspar Ultra with the following tint code:
For a quart:
Base C in 'Flat Enamel' or 'Matte' finish
101 - 41 (Lamp Black)
107 - 5 (Yellow Oxide)
109 - 3 (Red Oxide)
113 - 1Y44 (White)


This same tint code in a quart of Valspar Signature interior matte finish should work fine as well.

Keep in mind that this is the EXPERIMENTAL forum and these mixes are experimental and not ready for prime time yet. The more AAA-F you put into a mix the higher the gain will be, but this will increase the chance that the mix will have too small a viewing cone, or even hot spot.

Awesome! Thanks a million! I know this is the development forum and that's why I'm here. I'm excited to see how the test panels with the N5 base turn out. Only way to get it to prime time is testing right ?

You bet! Looking forward to your testing!

BTW, if possible, photos of your test panels, under room light and in use, would be great.

The testing I did do has shown that the new AAA-F has a MUCH reduced chance of adding any sparkles to the final mix compared to the old version.

As for making an even darker BWU™ mix, I have made some sample to test for color just using an N5 paint and the new AAA-F in ratios of 4:1, 2:1 and even 1:1 and the results have been quite neutral and NO sparkles have been detected except with a magnifying glass.
I'm not sure how I managed to miss this really promising information, but I was wondering if anyone would be able to comment on the approximate gain of BW mixed in these higher concentrations..especially with the darker shades of grey?

Does jumping from the older 1:4 ratio up to a half-AAA/half-grey push the gain up around or even beyond 1.0 or does it seem to only make a small change.

If anyone has done any measuring or just rough comparison to flat-white or paper, I'd love to hear it.

Re: Making a darker Black Widow™

Has anyone done any more work with the darker black widow? I've been happy with the original black widow for years but am in a new house and it's time for a new screen and I always wanted to try going darker.

I see the info Harpmaker posted above so i suppose i'll give one of those a try if there is no other new news.

Thanks again Harpmaker!

Thanks!

Mike

Re: Making a darker Black Widow™

Hi all, is there any update on the new BW darker formula? I have been researching DIY screens and was all set to go with the Silver Fire mix, until I stumbled upon the Home Theater Shack site and the Black Widow mix. Is the current Black Widow mix as outlined on the Wiki site the best tried and true mix at this point? I am fairly new to all of this, so just looking for a little input before making any decisions. Thanks in advance.
