Description

本発明は、印刷動作において色指定印刷を実現するための色変換装置、色変換方法、及びプログラムに関する。 The present invention relates to a color conversion device, a color conversion method, and a program for realizing color designation printing in a printing operation.

態様の一例では、印刷コマンドで指定されている指定色を複数の印刷色の内の１つに対応付ける対応付け部と、前記指定色の明度に基づいて対応する前記印刷色に印刷濃度を設定する設定部と、を備え、前記設定部は、前記印刷色が黒色またはグレー色のいずれかである場合、中間調として制御される前記明度の範囲を全範囲として前記印刷濃度を設定し、前記印刷色が黒色またはグレー色のいずれでもない場合、中間調として制御される前記明度の範囲を所定の範囲として前記印刷濃度を設定する。 In one example, an association unit that associates a designated color designated by a print command with one of a plurality of print colors, and a print density is set for the corresponding print color based on the brightness of the designated color. A setting unit, and when the printing color is either black or gray, the setting unit sets the print density with the lightness range controlled as a halftone as a whole range, and the printing When the color is neither black nor gray, the print density is set with the brightness range controlled as a halftone as a predetermined range.

Claims

An associating unit that associates a designated color designated by a print command with one of a plurality of print colors;
A setting unit that sets a print density for the corresponding print color based on the brightness of the specified color,
The setting unit
If the print color is either black or gray, set the print density as the full range of lightness controlled as a halftone, and if the print color is neither black nor gray, Setting the print density with the brightness range controlled as a halftone as a predetermined range;
A color conversion device characterized by that.

The setting unit
When the print color is neither black nor gray, the print density is set by setting the lightness range controlled as a halftone to be a predetermined lightness range or more;
The color conversion apparatus according to claim 1.

The association unit associates a designated color designated by a print command with one of a plurality of print colors based on a correspondence relationship between a preset classification color and a print color, and the setting unit Sets a print density for the corresponding print color based on the lightness of the classified color,
The color conversion device according to claim 1, wherein the color conversion device is a color conversion device.

The color conversion apparatus according to claim 3, wherein the color space is an HSL color space expressed by brightness, saturation, and hue.

The color conversion apparatus according to claim 3, further comprising an operation unit configured to set a correspondence relationship between the classification color and the print color.

6. The color conversion apparatus according to claim 1, wherein the designated color is a color expressed by three primary colors of red, green, and blue.

The color conversion apparatus according to claim 1, wherein the print color is a color of toner attached to the image forming apparatus.

An associating step of associating a designated color designated by a print command with one of a plurality of print colors;
Setting a print density for the corresponding print color based on the lightness of the specified color,
In the setting step,
If the print color is either black or gray, set the print density as the full range of lightness controlled as a halftone, and if the print color is neither black nor gray, Setting the print density with the brightness range controlled as a halftone as a predetermined range;
A color conversion method characterized by that.

On the computer,
An association function for associating a designated color designated by a print command with one of a plurality of print colors;
A setting function for setting a print density for the corresponding print color based on the lightness of the specified color; and
The setting function is
If the print color is either black or gray, set the print density as the full range of lightness controlled as a halftone, and if the print color is neither black nor gray, Setting the print density with the brightness range controlled as a halftone as a predetermined range;
