What is projector screen painting?

 

Projector screen painting is one of the less costly methods for watching high quality videos and media on a large screen of our choice. The advantages of using this type of method to view any media is that along with it being a cost effective alternative, it also gives us the flexibility to select the dimensions of the screen.

These types of screens are best suited for those who are living in homes temporarily and do not want to invest a huge amount of money in regular projectors which need to be dismantled in order to shift to a new place. 

 

What type of finish to choose for painting?

 

Most people who want to invest in projector screen painting prefer a paint that provides a flat or matte finish. A glossy finish on the projector screen is not recommended as it may cause too much reflection which may lead to obstruction in the visualization of the media on the projector screen.

During studies carried out to test various brands and types of paint finishes, it was found that using the flat as well as matte finish produced a picture that looked extremely dull on the screen. Thus a balance has to be achieved to find the perfect finish that ranges between matte and glossy in order to achieve a good picture quality which is usually provided by satin paint. 

 

How to choose the best Colour for projector screens?

 

The three most commonly used Colours for the painting of the projector screens include white, grey and silver. The white projector screen is one of the most preferred screen types for various purposes such as for home, school as well as office use. White is the go to Colour for screens as they provide a bright viewing canvass along with the most generous viewing angle for all the screen types.

Another reason why white is the most used Colour of projector screen is because this Colour is available in plenty of materials and it also comes with standard and matte finish both. White is a neutral Colour which does not dim or brighten others Colours. 

 

Grey projector screens are immensely popular as they help in reducing the contrast problems that occur with the use of early digital video projectors. The grey coloured projector screens are best suited for use in conference rooms which contain ambient lighting and when the projector screen needs to be used in the day time when the contrast needs to be shown and the images should be projected brighter even in the presence of light. The use of grey projector screens enhances the deepness of the contrast along with the sharpness of the image. 

 

Silver projector screens have the ability to increase the visibility of the whites and contrast colours appear more prominent as it provides better depth as well as increased perception of black as well as white colours along with all other types of colours in the spectrum. When a hot spot occurs on the projector screen, the silver screen must be coated with an emulsion or a conductive surface which is similar to that of a white screen. Such emulated silver screens offer good light diffusion and they are now days in demand as the preferred choice of projector screens. 

 

Why are these four factors considered while buying a paint? 

 

Room lighting 

 

The lighting that is present in the room is one of the major factors that should be taken into account while selecting a paint for the projector screen. Rooms that have white screens have the ability to reflect more amounts of light in comparison to black or grey screens. If the room is bright with ample amount of lighting, white paint is preferred to be used on the projector screen. In rooms which have dim lighting or when the projector that is being used is incapable of producing enough amounts of light that is not bright, then a grey paint on the projector screen should be avoided. 

Such rooms require a white projector screen paint with a substantial gain which has the ability to reflect the required amount of light back which helps in increasing the brightness of the media. 

 

Room brightness 

 

The amount of brightness that is present in the room where the projector screen needs to be used is a huge factor in deciding the colour of the paint for the projector screen. White coloured paint that is reflective is ideal for rooms that have ambient lighting that comes in from the windows and doors so that it can reflect adequate amounts of light from the surface of the projector screen. In dark rooms or rooms that are light controlled, a less reflective colour paint such as grey colour can be used. The advantage of using a grey colour paint that is less reflective is that it provides lesser light reflection from the walls of the room thereby making the room appear more dark leading to a better image viewing ability. 

 

Personal colour choice

 

Personal preference is also essential for choosing the right paint for the projector screen. When a white coloured paint is used on the projector screen, the images that are displayed will have greater reproduction of colour and vibrance but the black coloured pictures will not be displayed properly. When grey paint is used for the projector screen, it can display black colour well but the visibility of others colours will be less vibrant. 

 

Reflectiveness 

 

The brightness of an image that gets reflected off a screen in comparison to a standard reflection surface known as Lambertian surface is measured by using gain value. The presence of a high amount of gain leads to the formation of hotspots along with a reduction in the number of viewing angles thereby producing a dim image. In a dark or a light controlled room, the use of paints that have a lower gain value will produce a better quality picture. In narrow rooms, paints that have a higher gain value are preferred. Paints with the highest gain ratio have the ability to increase the brightness of the picture but they cannot produce accurate colour reproduction. Paints that have low gain are best used in combination with high lumen projectors. Paints with low gain value help in reducing the light that gets reflected back to the audience thereby enhancing the viewing experience.

How to paint your projector wall? Step by step:

 

Wall choosing

 

Selecting the wall in the room which you want to paint as a projector screen is a very step in determining the overall outcome of the image quality. The basic things to look for in choosing a wall for this purpose is that it should be extremely smooth and it should not contain any textural deformities. If any existing paint is there on the wall, it should be carefully removed by the use of a sandpaper or a scrapper. Any deformities that are present on the wall should be repaired and the holes that are present should be filled. 

 

Selection of projector screen area

 

The next step in this process is to determine the area where the image needs to be projected. For this purpose, all the lights that are present in the room should be turned off and all the natural light that is coming into the room from either the windows or the doors should be blocked. Next, the projector needs to be turned on and the image should be focused on the chosen wall. After properly adjusting the image and identifying the screen area, a marking of the outline of the image should be done in order to determine the projector screen area. 

 

How to select borders

 

Once the surface area of the projector screen is determined , the next step is to select the borders of the screen. The outline of the border should be marked by using a pencil and this area should be taped off. The typical choice of the border of the projector screen is usually a rectangular shape but other interesting borders such as bubbles and other patterns can also be used to impart variety to the borders. The border should now be painted with any colour that is found to be suitable and the tape should be removed when the paint is still wet. 

 

How to apply paint

 

First of all, the surface of the wall must be cleaned properly and a coat of primer should be applied on it. It is essential to apply a primer specially when the wall that is chosen appears to have a high absorbent nature or when it has never been painted previously. The next step is to determine the screen size which is obtained by marking the edges of the highest resolution image possible. A masking tape should be applied to protect the area from paint that is outside the area of the projector screen. Then paint that has been already selected can be applied either by spray method or by using a roller. 

 

Conclusion 

 

Painting a projector screen is an inexpensive way to create a screen anywhere and it can deliver high resolution images and thus provides an unmatched viewing experience. While painting the projector screen, due care must be taken to avoid any irregularities for obtaining the best image quality which is determined by the type and colour of the paint used. Painting projector screens comes handy when the exact size of the screen that is required is not available or when it is a hassle to set up permanent projectors mainly in temporary residence. The choice of the paint depends on the lighting as well as the brightness of the room where the screen needs to be placed.
