ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to color printing methods, and in particular, to a color printing method using various metallic colors such as metallic gold, and other colors (hereinafter referred to as “characteristic colors”) having special tones.
2. Description of the Related Art
In color printers, in general, color-image data to be printed, created using a type of application program, are input to a printer driver, and the printer driver controls the operation of printing in accordance with common red, green, and blue (RGB) color-scheme components recognized by both the application program and the printer driver.
Such conventional printers use four primary colors, yellow, magenta, cyan, and black, to perform printing using approximately 16,000,000 colors.
Recently, not only conventional color printing using the four primary colors, but also color printing using characteristic colors such as metallic gold is performed.
For performing color printing using characteristic colors, the conventional printers use, between the application program and the printer driver, predetermined RGB color-scheme components fixed for characteristic colors. When the application program creates color-image data, it uses the RGB color-scheme components to designate a characteristic color region, and the printer driver performs color printing in accordance with the fixed RGB color-scheme components used for designation. Each fixed RGB color-scheme component is normally set for each characteristic color. For example, RGB color-scheme components fixed for metallic gold are set as follows: R=64/255, G=72/255, and B=200/255.
In an application program that cannot set a color scheme by using the above-described, predetermined RGB color-scheme components fixed for characteristic colors, printing using characteristic colors cannot be performed.
In order to perform printing using the desired colors, an application program that can designate fixed RGB color-scheme components corresponding to the desired colors must be used.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide a color printing method for securely performing high definition color printing using characteristic colors without using a special application program.
To this end, the foregoing object is achieved through provision of a color printing method including the steps of displaying a print image based on color-image data to be printed, as a preview image, on a display designating each print content in accordance with each print purpose for the previewed print image; and performing color printing based on the color-image data in which each print content is designated.
According to the color printing method, high definition printing using colors including characteristic colors can be securely performed without using a special application program.
The print content designation may be performed by automatically selecting a preprint/glossy-finish region obtained by analyzing a spool file input as the color-image data, designating a conversation mode for the preprint/glossy-finish region, and designating RGB color-scheme components for each object which are determined by the conversation mode designation.
According to the color printing method, operability is greatly improved. A high degree of freedom is obtained because a user arbitrarily designates regions to be processed and color-scheme components while viewing a preview image, and fine adjustments can be performed.
The designation of the RGB color-scheme components may be performed such that predetermined RGB color-scheme components fixed for characteristic colors, used by the printer driver, are designated for each characteristic color object designated in the spool file, and ordinary RGB color-scheme components are designated for each ordinary color object designated in the spool file. According to the color printing method, operability is greatly improved.
In addition, the designation of the preprint/glossy-finish region may be performed by selecting the use of a preprint region only, the use of both preprint and glossy-finish regions, the use of a glossy-finish region, or region cancellation. Accordingly, operability is greatly improved.
