Blackout Cloth + SilverScreen + Ambient Light Controlled + Epson 8350 Question

Painting the BOC with a simple solution such as Behr Silver Screen "color chip" 770E-2 with this:

......is something I thing will float well in your Pond. It's roll-able too.

I think MM's url got cut off.. saw him recommend mixing behr silverscreen with this in another thread so I think he meant to past this one, looks like a premixed can of primer and flat interior enamel, I guess the primer is for it's priming qualities and the enamel is to lighten the silverscreen?

Thanks for the catch...but the linked-to paint is a Primer-Paint Combo, a genre that is becoming quite popular among several Paint Mfg. It's always a better quality paint anyway.

Since BOC is under 1.0 gain, and usually Mfg so as to be uniformly coated, when one also manages to stretch it evenly and tightly, all the aforementioned attributes you state are there to enjoy. You at least seem to be at that point, and you bet, people have been heralding the attributes of BOC Screens since the first one went up. However when comparing BOC to other applications, quite often one still sees the advantages in having a Screen with at least unity gain, if not indeed a surface that enhances perceived contrast

However, when looking at your thread's title:

Blackout Cloth + SilverScreen + Ambient Light Controlled + Epson 8350 Question

....one would surmise that some degree of ambient light performance is desired, and that you have in the least recognized that a Gray surface is going to provide that. (...like the HCCV screen did, but along with other detrimental aspects as well...)

Understand that it's those very undesirable aspects that exist with many Mfg Screens, as well as with some very basic DIY solutions, that drives the effort to make DIY Screens that are not just effective challenges to Mfg Screens, but that also exceed the performance expectations of those who aspire to have something better than they ever though possible.

BOC is Good....but it's simply that...Good. It can be made better.

Here are the facts;

The 8350 can use some "screen" assist...even in a totally dark room, with presenting the most absolutely best Contrast possible. A Gray can get'ter dun. I know......I've been there and done that a few times myself.

A Neutral Gray of the correct shade, when applied to a surface correctly, will often provide an even smoother image than BOC. In every instance? No...but that would be 99% "builder related".

If one employs no reflective additives to increase gain (...something you seem to not need nor want....) then it's universally accepted that a light Gray surface has the ability to create the proverbial "Looking through an Open window" effect. If that is accomplished and both a perceived increase in Black level rendition as well as some ambient light tolerance is added into the equation, then it should be easy to ascertain what you have to gain by painting the BOC.

I am interested in the build as well. I will probably attempt to do this same thing this week.

Well good!

Post up if you have questions or need any help or advice.

You might want to look at the projectorcentral review of that silverscreen recommendation. On the DaLite screen you didnt like the pearlescence that was added to the screen. Some people actually like this and you will see that people here are adding it to their recommendations of what they are recommending and even trying to sell on the internet as a coating. Most people are in the same boat as you when they see the difference of a screen that isnt adding anything to the picture. Unfortunately I havent seen a formula here that matches your description. Much of the data I have read is from colorometry for printing. Without going through great detail you will note from the review from projector central what is acceptable here as a silverscreen is actually described as a mess with the only attribute that watching screen credits is good. The only ingredient in many of the solutions that makes some sense in many cases would be the water to clean with.

My suggestion is to read the projectorcentral article and possibly try what Evan from that site recommended. I can say that I shared the same experience with the silverscreen. Further what Evan came up with seems to match your requirements at least as a starting point.
Good luck.
