    • A reflection type projection screen has the following construction. A base fabric (4) of glass fiber, a white opaque base material sheet (3) formed of a plastic sheet and a translucent plastic light diffusing layer (1) in which a luminescent pigment or calcite powder is mixed are provided in the described order on a light absorbing layer (5) formed of a dark plastic sheet or solidly printed with a dark ink. Emboss (9) is applied onto the surface of the light diffusing layer (1). It is preferable to provide a reflecting layer (2) printed with ink incorporating therein the luminescent pigment or calcite powder is provided beneath the light diffusing layer (1). Light absorbing stripes (11) are provided on the surface opposed to the light diffusing layer (1) of the base material (3) and in positions corresponding to recesses (9a) of the emboss (9). Furthermore, there are disclosed the method of effectively manufacturing the reflection type screen having the emboss and the system for manufacturing the same.
    • 反射型投影屏具有以下结构。 以玻璃纤维的基底织物(4),由塑料片形成的白色不透明基材片(3)和混合有发光颜料或方解石粉末的半透明塑料光漫射层(1)按照上述顺序 在由深色塑料片形成的光吸收层(5)上或用深色墨水牢固地印刷。 将浮雕(9)施加到光漫射层(1)的表面上。 优选的是,在光漫射层(1)的下方设置印有墨水的反射层(2),其中包含发光颜料或方解石粉末。 在与基材(3)的光漫射层(1)相对的表面和对应于浮雕(9)的凹部(9a)的位置上设置吸光条(11)。 此外,公开了有效制造具有压花的反射型屏幕的方法及其制造方法。
