1. A coating system comprising:
an ingredient ink supply portion supplying ingredient inks used in a coating method, each of the ingredient inks being a coating liquid that contains a light-emitting material being an organic compound; a first pipe connected to the ingredient ink supply portion; a stifling tank comprising an ink stirring mechanism and connected to the ingredient ink supply portion through the first pipe a supply regulator portion provided on the first pipe and regulating the respective amounts of the ingredient inks supplied to the stirring tank; a controller portion connected to the supply regulator portion through an electric telecommunication line, determining a mixing ratio of the ingredient inks, and controlling operation of the supply regulator portion based on the mixing ratio; and a coating device comprising an ink transport portion connected to the stirring tank through a second pipe and comprising an ink discharge portion connected to the ink transport portion through a third pipe, wherein the controller portion has functions of receiving request ink data, receiving a standard ink data set and determining a mixing ratio of a plurality of ingredient inks based on the standard ink data set and the request ink data, wherein standard ink data constituting the standard ink data set are the correlation between a mixing ratio of the ingredient inks in terms of weight ratio and a chromaticity of the light-emitting color, and are selected in a manner that coordinates are distributed in a larger area in the chromaticity coordinates, determining the amounts of the ingredient inks supplied to the stirring tank based on the determined mixing ratio, determining operation of the supply regulator portion for supplying the respective ingredient inks in the determined amounts and outputting a setup signal for performing the operation from an output portion, and the supply regulator portion supplying the respective ingredient inks in the determined amounts into the stirring tank based on the input setup signal, stirring the supplied ingredient inks with the ink stirring mechanism provided in the stirring tank to prepare a mixed ink for coating, and applying the prepared mixed ink onto an object, and wherein the controller portion, in the step of determining a mixing ratio of a plurality of the ingredient inks comparing the standard ink data set comprising three or more standard ink data with the request ink data, calculating distances between coordinates in chromaticity coordinates of the respective standard ink data and coordinates in chromaticity coordinates of the request ink data to obtain distance data set, ranking the distance data set and the corresponding standard ink data set in ascending order of the distance based on the obtained distance data set, obtaining an equation of a first straight line passing through first coordinates of the first place and second coordinates of the second place in the ranking, determining a-th coordinates corresponding to an a-th place in ranking, the a-th place being highest except the first coordinates and the second coordinates in the standard ink data set, such that the coordinates of the request ink data are comprised in an area surrounded by straight lines passing through the first coordinates, the second coordinates, and the a-th coordinates, at the controller portion, obtaining an equation of a second straight line passing through the a-th coordinates thus determined and the coordinates of the request ink data, obtaining coordinates of an intersection point of the first straight line and the second straight line, determining whether at least one of conditions (1) and (2) is satisfied, (1) x-coordinate value of the a-th coordinates≧x-coordinate value of the request ink data≧x-coordinate value of the intersection point, and (2) x-coordinate value of the a-th coordinates≦x-coordinate value of the request ink data≦x-coordinate value of the intersection point, obtaining a first distance value from the firs coordinates to the coordinates of the intersection point and a second distance value from the second coordinates to the coordinates of the intersection point, determining the mixing ratio of the ingredient inks at the intersection point based on the first distance value and the second distance value, obtaining a third distance value from the a-th coordinates to the coordinates of the request ink data and a fourth distance value from the coordinates of the request ink data to the coordinates of the intersection point, and determining the mixing ratio of the ingredient inks for the request ink data based on the third distance value and the fourth distance value. |
