how do you measure the GAIN of a projection screen/surface?
I want to measure the reflective Gain of some materials im using to make a projection screen, i know that it is also dependant on your individual projector, but i would like to know how to measure this factor.

I have a light measuring devise used for professional photography, but does the white surface need to be Matt, Shiny, frosted?

Gain is a measurement of the reflectivity of any screen or projection surface. The gain number represents a ratio of the light that is reflected from the screen as compared to the light reflected from a standard white (magnesium oxide) board. Therefore, a screen with a gain of 1.0 will reflect the same amount of light as that from a white board. A screen rated at 1.5 gain will reflect 50% more light as that from a white board, whereas a gray screen with an 0.8 rating will reflect 80% of the light from a white board.
Gain is measured from the vantage point where the screen is at its brightest, which is directly in front and perpendicular to the screen. Technically the measurement of gain at this point is known as Peak Gain at Zero Degrees Viewing Axis. If you move to the side and view the screen at an angle the brightness of the projected image drops. The angle at which the gain reading drops to 50% of the peak value is known as the Half Gain Viewing Angle. A person viewing the screen from this angle will see an image half as bright as the person seated at the center position.
Low gain screens have wider Half Gain Viewing Angles than do high gain screens. That is because the low gain screen diffuses light more evenly over a wider angle of view. A high gain screen is constructed to reflect more of the projector's light energy back toward the centerline of the projection path, and less light energy to the oblique angles of view. Thus brightness falls off more rapidly as you move away from the zero degree viewing axis, and the Half Gain Viewing Angle is relatively narrow.
Do you have calibrated optical measuring equipment and a standard white board reference?
