摘要

在紡織工業中，電腦配色原理成功的應用於色彩複製上。一色樣的複製只要透過分光測色儀，測得色樣和色母的基本資料的反射率或CIEYxy值，利用Kubelka-Munk原理取得此色樣的起始配色配方，再經由電腦修色後，即可完成此色樣的複製。本研究則將此電腦配色原理應用於熱昇華式的彩色印表機，利用熱昇華式的彩色印表機複製Munsell色票中明度為5的中明度色票。實驗結果發現經過兩次的電腦修色，平均色差ΔE(下标 ab)=3.52，其中色相B的色差最小，平均色差ΔEab為1.97，色相YR的色差最大，ΔE(下标ab)為5.42。

In the textile industry, computer match prediction is successfully applied in the color reproduction. Based on Kubelka-Munk theorem, we predict the recipes of the samples from their reflection of samples and primary dyes we choose. We modify the recipes through the computer calculation in order to obtain the more accurate color reproductions. In this paper, we applied this method on the sublimation color printer. We reproduced the Munsell chips with a value at five (V=5) using the sublimation printer. From the result of the experiments, we found the average color difference is 3.52 (ΔE(subscript ab)=3.52). The average color difference of the hue B chips is the minimum (at 1.97) and that of the hue YR is the maximum (at 5.42).
