本論文使用Epson所生產型號為L1110之彩色噴墨印表機進行列印。 列印出不同灰階的色塊。並對列印出的色塊進行量測,取得反射率光譜。接著藉由主成份分析法建立單色色塊反射率光譜預測模型,並藉由混色模型來分別預測雙色及三色色塊混色反射率光譜,最後將單色與多色噴印模型之各項參數與墨水噴印面積進行比較,找出墨水噴印面積與反射光光譜之關係。;In this thesis, all the color outputs are printed on the standard printing papers by the color inkjet printer of EPSON L1110. By measuring and analyzing the reflective spectra of all the printed color samples, a spectrum model for any certain single-color spectral reflectivity is established and applied for the prediction of the two-color and three-color mixing reflectivity spectra. Moreover, all the parameters found in the models are also well explored.
