|
|
My screen is in need of re-painting and I was wondering what's the best paint to use?
I originally painted it with Ultra White Eggshell and that worked pretty good but I'm having to run the brightness pretty high to get good whites.
I could use a bit of gain but would like to do this with paint I can get localy.
Any suggestion?
Ernie

There is a lot of information here regarding screen paint, try doing a search and you will find it. Where is locally?
You might want to post your question in the Screens forum as well.

Go to the screens section and start with the"Sticky" at the top and read you way through the posts.

honestly Ernie there is no piant out there that can compare to a proper screen. If your not running on a shoe-string and can you spare a few sheckles a pro screen is worth every penny. You will gain anywhere from 20 to 50% more light output,better color balance,and a sharper image.

Last I priced pro screens in the 8' X 6' size they were quite expensive so I just ruled them out.
I'll give them another look and see what can be had within my somewhat limited budget.
Thanks

A Wilsonart Designer White screen wouldn't cost a lot more than paint, and it should look a lot better.

a 110" rigid frame showed up at the shop a while back and it was only $350, i think. it had good PQ and was easy to assemble/disassemble. It even had a velvet lined aluminium frame.

I've seen Studiotek 130's a number of times, and I don't think my Gesso on Blockout Cloth screen is particularly lacking in comparison.
It's not that big a difference, not like adjustable masking, for instance.

Well it's a matter of opinion. I don't nkow what you pianted your cloth with but I had the opprotunity to see the dim,gray picture of straight blackout cloth and It was pretty bad. The PJ was cranked up 20% over contrast default and putting out 20% less light off the screen.
I had a Goo painted screen too and it sucked. Behr Ultra white from home depot was OK,and the only thing I would consider if I was broke and couldn't buy a nice screen.

Dragan, Gesso is an uber-white paint. You can't compare my dingy BO screen to a Gesso-painted BO screen.

You're probably all right - sorta. I'll throw a few facts out for the sake of discussion:
- Plain blackout cloth is less than 1.0 gain - probably closer to .9 than 1.0. IMHO, no CRT projector user should be using an unpainted BOC screen, unless he's running a really small screen size.
- I've never seen a gesso-painted screen, but if it's matte, then the gain can't be much beyond 1.0 - maybe 1.1 at most.
- StudioTek 130 is a true 1.3 gain material.
- Wilsonart was measured at ~1.3 gain.
- No matte white painted screen will exceed 1.0 gain - maybe 1.05 or 1.1 at the outside if it has some sheen to it.
Mark, the StudioTek 130 you saw... Did you compare it at the same size as your screen and with your projector? If not, I can't see how it's a meaningful comparison to say your gesso screen isn't lacking in comparison. Your frame of reference is what's lacking. You'd need to see them side-by-side or at least have samples side-by-side or overlaid. I think you can get away with your ~1.0-1.1 gain screen because your screen size is on the small side. Hardly anybody here runs a screen that small.

I couldn't disagree more. A 1.3 gain screen will be noticeably brighter than a 1.0 gain screen. That added brightness (and contrast!) will give the image more "pop" - more "life". Whites are whiter, colors are richer. To use a metaphor, if the projector is like an amplifier, then the screen is like a speaker. It's a critical component of the projection system!
Anybody who's running a plain BOC screen (Gary... Gary... Are you listening?) would do well to replace it. Even a WilsonArt screen would be a big upgrade in image quality/brightness.
Cheers,
SC

Yeah, yeah...  I keep intending to get a sheet of Wilsonart but it just hasn't made it to the top of the to-do list...

Yeah, just about like that.  Unfortunately I was stupid when I finally built a frame (just a few months ago) and the screen area is 48.5" high. I think the 4x8 usually runs 49" wide but that's cutting it pretty fine. Maybe I could get away with a 4x8 sheet if I place it juuuust perfectly... or maybe it'd be smarter to spring for the 5x12 and have plenty of overlap behind the frame.

His name was algol and the thread was "Mommy, Daddy's Painting the Screen... Again!". It's in the archives now. I wish people who haven't actually compared a properly done Gesso screen with a Stewart would quite saying how much a painted screen sucks. That is just plain false and misleading.
I used a modified algol formula using the iridescent mica flakes. I later got a great deal on a Stewart screen so I switched. In the process I put the Stewart screen on half the image in front of the Gesso. There was a VERY slight difference (mostly in color shift but NOT so much in gain). I would roughly estimate the gain was almost the same. And given the fact that the Stewart was around 1.3 I estimated the Gesso was also about 1.3.
Sure plain white paint is 1.0 but please, if someone is willing to mix up $60 in Gesso paint they can get a VERY close second to a $2,000 Stewart screen.
BTW, we just had this argument not more than a month ago...OP...please do a search before posting such questions.

A ~2m wide screen with a Reality 909, and samples held over a painted blockout cloth 4m wide screen with a G90.
As well as some other commercial screens.
The only one that really had extra punch was a glass beaded screen, but it caused sparklies and hotspots.
None of them have made my jaw drop - not, for instance, like seeing an XG compared to a 12xx Sony, or an Xtra to XG-LC, or seeing the difference adjustable masking makes.
But yes, my 2.1m wide screen is not huge, and I run contrast pretty high (got tubes).

I'm amazed you say adjustable masking makes such an enormous difference. Yes, I'm sure it's nice not to have the not-quite-dead-black bars above & below a scope film image, but is it really THAT huge a deal?
