Abstract
A method of controlling the luminance of a transmissive board at the moment of transmissive illumination by providing the steps of determining a criterion number of ink transfers by roughly controlling the luminance of the highest luminance at the moment of transmissive illumination to closely reflect the lowest transmissive luminance on the board, determining the criterion area-ratio by the minor control of the luminance on the board so that the higher luminance most closely reflects the luminance of the lowest luminance on the board, and equalizing the luminance of all luminance on the board so that all luminance is controlled to be the lowest luminance of the transmissive board at the time of transmissive illumination by a light source by the transfer of ink according to a prepared processing number. Also provided is the transmissive board wherein the transmissive luminance is controlled by the method of the invention.
