I know cylab said he had considered making a screen with a black mirror tint like film & I have considered something like that as well. My previous project consisten of acrylic for the diffuser to smoothed out over but what if I bouth the same type of sheet but in glossy black because the black pieces are virtually like black mirror tint because there very glossy. Then you could wet apply a diffuser film that I would recommend being 60"×9'. That way it over lapse every side on the axrylic. The hardest thing I had a problem doing was trying to even up a 48" film on a 48" piece of acylic. That was the toufhest part so the next time I ever try to pain stakingly wet apply a film it will be larger on all sides. I know I have expressed my concerns with wet apply a diffuser but I may take one more crack it but this time I will be more prepared. So what do you guys think about the black gloss acrylic sheet or wet applying a black chrome vinyl to an acrylic sheet?

I would say give it a try

Some tips for the wet application:
- bring in two friends (better 4) - one holding each corner and you do the application
- use professional transfer fluid
- don't be tightfisted with the fluid - the more the better
- immediately spray on the adhesive side of the film while peeling up the liner!
- spray on the substrate, lay down the film, spray on top of it again
- use some transparent film as protection while wiping out the fluid - this way you can see, what you are doing and don't damage the diffuser
- be patient - don't touch a layer for at least three days after application

No I still haven't made a full screen in these last couple weeks but my time away from the forum hasnt been in vein. I was starting to believe that a diy black screen wasnt possible essentially because we were only able to get descent results with gray only samples but I believe I have made a "black" screen sample that could be a game changer for us. Here are some pictures of my results & there the best results I have had so far. I feel as if I am very close to to getting what many of us are looking for. The comparison screen is a smoke gray screen so the contrast is already pretty good but if I compared the black sample to a white screen it would be night & day. There doesnt appear to be any hotspotting & the viewing angle is high. You will be able to tell from the pictures taken from the sides.No I still haven't made a full screen in these last couple weeks but my time away from the forum hasnt been in vein.

Looking good stephen, what materials/method are you using? Potential limitations (cost/material based screen size limits/assembly techniques...etc)?

Personally I think any picture of these black screens should most importantly show how the screen/sample looks with no image on it in as much light as humanly possible. That way whatever results one sees is instantly quantifiable.

This material is simply high gloss black vinyl with a very light coat of window frost spray paint. Im ordering other shades of black & charcoal. In an attempt to get the perfect balance of dark screen material and optimal picture brightness. The spray paint just needs a light one layer spray because to much smothers the reflective layer resulting in to dim of a picture. I really didn't think the spray paint would work but to my surprise it works very well. It eleminated hot spotting & the black wasn't washed out into a gray. Also the application process I believe is a lot easier then trying to wet apply a hug diffuser. One of the most exciting things about this process is the fact that you will be able to make screens up to 130 inches diagonal because they make these types of vinyl up to 60 inches wide & with the spray frost there is of course no limit for how much you can spray. I encourage anyone with an extra 8$ to go to home depot/lowes & buy a $4 piece of black gloss acrylic (which has the same effect as vinyl) & a can of frost spray paint. Then just lightly spray one coat over the black acrylic & let dry. In about 5 minutes u should have a good test sample. Make sure you dont spray to much or it will smother it out. Just a quick dash across the top & bottom should be good. As previously stated im still looking for different shades of black, charcoal, & dark gray vinyls to narrow down the search for the best balance of dark material with optimal brightness so if anyone else wants to help with the hunt jump on in. Black chrome vinyl will work as well but it tends to be more dark gray then black but that may be the way to go so we can get the brightness we are looking for. I really think the reason all the current market dark screens are dark gray is because black severly dims the white light spectrum of the picture. I do believe that that a charcoal or a dark gray will get us the best overall picture. I have found samples on ebay for just 2-10$ shipped. Just put in the color then vinyl & it will give hundreds of car vinyl results with many roll sizes. Also a fabric high gloss vinyl should also work allowing us to simply stretch it over a frame & then spray the diffusser on.A roll large enough for a 130 screen will only cost about 60-70 bucks. Something else kind of exciting is the ability for this screen to be applied to a roll down screen.

Here is a picture of the material In better light. The marks on it are from peeled off diffuser residue from previous experiments.
