Today, we will go over any highly visible mistakes that occur when tab-tensioned motorized screens are not designed correctly for the amount of drop selected.
All projection screen venues will need to be properly measured. While a majority of people do this, some others make the mistake of just adding drop and then fixing the positioning during the installation. The tab-tensioning cable relies heavily on the screen’s complete or near-complete deployment. The cable pulls the screen flat and holds it there only when it is completely extended. So, it is good to take the extra steps and make sure that your clients are satisfied.
Another mistake is when the screen itself does not meet the 4 to 3 rule. All tab-tensioned screens need to have the overall width of the screen at least 1.33 times the height. Having a wider screen is fine, however, less width leads to wrinkled corners. Do not let yourself fall victim to this simple failure. You can add in more side bordering if you need to to help you get the best outcome.
Consider creating a design process that starts with just the shape of the screen without the image. Think about these four steps:
- Plan the placement of the case, figure out how high it will be;
- Plan the bottom of the screen, and know how low it is;
- Plan how wide the screen will need to be, will it need to hide things, or will it be limited by the side walls;
- Does the width exceed the height by at least 1.33 to 1.
Once you have this blank rectangle, overlay the image area. The bottom of the image must be visible to all viewers without obstructions from the furniture, heads or raised stages. The height of the image should be tall enough to have images clearly visible from the back row.
The width of your image will be chosen based on many different factors like content, projector aspect ratio and lens. Place this image inside the black rectangle. Everything else will be a black border.
Another mistake is to go with painted borders instead of welded ones. Painted borders can chip and cause stickiness from being rolled up for a long period of time. Welded borders are made from PVC and they will never chip, peel or become sticky.
When you understand the common pitfalls of motorized screens, you will be prepared to install your screens perfectly by being able to design the best tab-tensioned motorized screen possible.
