PCT No. PCT/EP89/01218 Sec. 371 Date Jun. 11, 1991 Sec. 102(e) Date Jun. 11, 1991 PCT Filed Oct. 13, 1989 PCT Pub. No. WO90/04166 PCT Pub. Date Apr. 19, 1990.An apparatus and method for measuring the gloss of a surface with a light source projecting light in the direction of the surface and a light-sensitive sensor receiving the light reflected from the surface and converting it into an electrical signal value. A memory storing a program for calculating the characteristic gloss value, a computer for calculating a characteristic gloss value from the electrical signal value, and a display for visually displaying the calculated characteristic gloss value are provided. Five or more reference value pairs are stored in the memory, each pair consisting of a reference characteristic gloss value and a corresponding reference electrical signal value measured by the apparatus on the basis of the reference surface. The measured electrical signal value is compared with the reference signal values and at least the next higher and the next lower value for interpolating the measured gloss.
