If you are interested in a diy vinyl projector screen there are several things you will need to know before using this projector screen material. These include the difference between supported, and unsupported vinyl, the best uses for each, and how to attach the vinyl to a flat surface. This is important for creating the best projector screen possible for your home theater projector.
What Is The Difference Between Supported and Unsupported Vinyl?
The difference between supported and unsupported vinyl is that supported vinyl is textile-backed which prevents it from crumpling, and allows it to hang flat without any tension. This is very important for obtaining the best possible picture from your diy projection screen. You will want to have the flattest possible screen. Without this tension you will lose planarity with the projection screen, and this will ruin the picture from your projector.
What Is The Best Use For Unsupported Vinyl In A Projection Screen?
The best use for unsupported vinyl is in a situation where you will be creating a fixed projector screen. The reason for this is that there will always be tension on the screen. Without tension this vinyl is not useful for projections because as stated earlier planarity is key. While you may not be able to see them with the projector off any ripples will become more visible with the projector on. Unsupported vinyl is sometimes used in portable screens that have an included mechanism to provide tension.
What Type Of Projection Screen Should Use Supported Vinyl?
Supported vinyl is the type that is best suited for portable projector screens. The reason for this is that it does not require tension to sit flat so even in less than ideal situations you can get a good picture. Supported vinyl is also best for portable projection displays because it is typically more durable than unsupported vinyl. Supported vinyl is considerably more expensive than unsupported vinyl, but it is a good choice if you will not be using the screen in a situation where it can not be permanently tensioned.
What Should I Watch Out For When Using Vinyl?
If you are attaching vinyl to a flat surface the recommended choice is unsupported vinyl, and the best way to do it is to stretch the vinyl around the back of the surface, and attach it to the back. Attaching the screen through the front can make it difficult to get any ripples out. Supported vinyl can be used for this purpose too, but it is considerably more difficult to attach without ripples, and the high cost of supported vinyl does not make it worthwhile to make your own projector screen in this situation.
