Rück projection is primarily used to present a projected image or video in an aesthetically pleasing and functional way. It offers numerous advantages compared to classic front projection and is used in various areas:

1. No shadows cast: As the projector is positioned behind the screen, people or objects can stand in front of the screen without obscuring the image.
2. Improved image quality: Rück projections are less susceptible to ambient light, allowing for a clearer and higher-contrast image in brighter rooms.
3. Professional optics: The technology ensures a clean, tidy appearance as the projector remains concealed.
4. Space-saving: R&R projection with short-throw projectors is a space-saving solution, especially in confined spaces.

Rück projection is a special technique in which the image is projected by a projector onto the back of a translucent screen and is visible to the audience from the front.

This technique requires certain prerequisites: a projector suitable for rear projection that provides sufficient light intensity and a special screen that distributes the light evenly and reproduces it clearly on the other side.

Requirements for the projection screen

A special projection screen is required for room projection. Unlike standard screens, which simply reflect the light, a projection screen is made of a special material that allows light to pass through in a controlled manner. This screen ensures that the image not only remains bright and sharp, but is also evenly distributed. At the same time, it minimizes disturbing influences such as reflections and ambient light. Thanks to its specific properties, it reproduces the projected image clearly and with high contrast on the front, without distortion or loss of detail.

Choosing the right projector for room projection

There are a number of requirements that need to be met in order for room projection to work. One key aspect is the projector, which must be suitable for this method. Projectors suitable for rear projection are usually characterized by a high luminous intensity, which is measured in lumens. This brightness is important so that the projected image retains its luminosity even when it penetrates the screen and is clearly visible to the audience.

Not every projector is suitable for rück projection. Short-throw projectors are particularly practical in confined spaces, as they can project a large image from a short distance. Devices with at least 3,000 lumens brightness are recommended for bright environments. Also check whether the projector supports R&R projection and has suitable connections.

1. Positioning of the projector:
   • Position the projector behind the screen.
   • Select a shielded area to minimize external light sources.
2. Set the distance:
   • Short-throw projectors: Require only a few centimetres distance to the screen.
   • Standard projectors: Require a greater distance, depending on the image size and projection power.
     
     
3. Height and alignment:
   • Make sure that the projector is centered in relation to the screen
   • Adjust the height so that the image does not appear distorted.
     
     
4. Adjust the focus:
   • Precisely adjust the focus to obtain a crisp image.
     
     
5. Use keystone correction:
   • Use the keystone correction function to correct skewed or distorted image edges.
   • Aim for a rectangular and symmetrical image projection
     
     
6. Cable management:
   • Organize cables so that they are not visible or in the way
   • Avoid tripping hazards or unclean installations.
     
     
7. Perform a test run:
   • Test the projected image to make any necessary adjustments.
   • &please check brightness, contrast and color fidelity under real conditions.
     
     

These steps ensure that the projector is set up optimally and that the projection delivers a perfect result.

Our tip: Light scattering can impair the image, so rooms should be darkened and external light sources blocked. Sharpness problems can be solved by regular calibration and

R&UMl;ck projection offers numerous application possibilities, as it provides a high-quality and distortion-free image. Here is an overview of the most important areas of application:

• Home theater:
  Provides an immersive film experience, as distracting shadows are completely avoided and the technology remains in the background.
• Business presentations from companies:
  Ideal for conference room set-up, as it creates a tidy and professional atmosphere that is particularly suitable for important meetings or presentations
• Showcase advertising:
  Impresses with vivid images that showcase products and effectively attract the attention of passers-by.
• Museums and exhibitions:
  Perfect for interactive displays or visual installations where the technology remains invisible and the focus is entirely on the content shown.

Thanks to its versatility, Rück projection is ideal for any environment where a high-quality and professional image is required.

Room projection with a projector offers you the opportunity to present content in an aesthetically pleasing and professional way. With the right combination of projector, screen and set-up, you can achieve optimum results.</p
