Abstract

Abstract Translated from Japanese (57)【要約】 【課題】 用紙などの画像保持材の表面特性に左右され ることなく、均質な光沢を有する質感の高いカラー画像 を再現することが出来るカラー画像形成装置を提供す る。 【解決手段】 透明色材量制御回路20は、画像保持材 選択部30を介して選択された画像保持材の表面特性 と、下色除去後のY信号、M信号、C信号と、K信号の 各信号のうちから得られるトナーの濃度を示すカバレッ ジデータの最大値とにより、透明トナーの重畳量を決定 する。透明色材の重畳量を示す情報Tは、中間調回路1 7において面積変調されて、透明色材画像形成部182 に供給されて、画像保持材上に透明トナーよる画像が重 畳される。 (57) Abstract: Provided is a color image forming apparatus capable of reproducing a high-quality color image having uniform gloss without being affected by surface characteristics of an image holding material such as paper. A transparent color material amount control circuit (20) includes a surface characteristic of an image holding material selected via an image holding material selection unit (30), a Y signal, an M signal, a C signal, and a K signal after undercolor removal. And the maximum value of the coverage data indicating the density of the toner obtained from each of the above signals, the amount of superimposition of the transparent toner is determined. The information T indicating the superimposed amount of the transparent color material is stored in the halftone circuit 1 7, the area is modulated and the transparent color material image forming unit 182 is formed. And the image formed of the transparent toner is superimposed on the image holding material.
