I have a brilliant 120x120 silver screen that I love to use, but it has "dents" in it that annoys me?

Looks like this:

Is there anyway to fix this? I've tried leaving it over night to stretch, didn't help.

Hi Christian,I don't think there's a cure, as that is usually how these
screens look when extended.One point, is that it should be set
for your film format at 4x3.You could also mask the edge in black
by a couple of inches which would make your problem less
noticable and also give your picture "impact".I did it with one of
my tripod screens, and the black border does give the projected
image a better look.

Hi Kevin, according to the Elmo ST1200 manual the two types of grease that should be used are Lithium based grease and Alvania type grease depending on which particular part of the assembly you are working on. Regards Andrew

I'm puzzled about grease diverting a thread about a screen!

I agree that it would be very difficult to eradicate the lines - it looks like the material is relatively thin and has been tightly wound for a very long period, but if you leave the screen open for a prolonged period, preferably in a warm room, you might see a modest improvement.

I wonder if you could steam the lines out? Maybe from the back side?

Just a thought.

There really is no way to fix "dents" on that screen. The fact is,once you start to fool with them they ger worse and show up more.

Pat is absolutely right there Chris,I myself have a small silver
screen with exactly the same surface problem,and of course it's
much more evident because as you know silver is directional.
The only time I have had totally flat surfaces, were on two silver
screens I made myself which were stretched on wooden frames.
The largest was about 7' square and was for my father to view his 35mm slides on.There were no surface indentations and it wasn't lenticular,the material was from a company now gone
called CLEARVUE who had a fantastic selection of screen
materials, cut to any size and very reasonable.Unfortunately as
you know, roller screens can be vexing when you want a flat surface, and I'm afraid that this is going to be an ongoing problem,some of your indents might go in a warm atmosphere
but once rolled up and stored will be there again.I can understand why you like silver as it does give added depth to
any B/W film, the only solution is to view in line with your projector and so avoid any directional shadow.
