Chapter3 Handling Color Correction There are the following three methods for color correction. • Setting on the printer • Setting using OS • Setting using an application software According to which method you use, set [Color Correction Mode] of the printer driver as follows. • Setting on the printer: Set to [Epson Vivid Color], [Epson Preferred Color] • Setting using OS: Set to [ICM] for Windows, Set to [ColorSync] for Mac • Setting using an application software: Set to [None] Relationship Between Driver Settings, Color Correction Methods, and Spot Color Settings The color of the print result varies depending on the menu settings on the driver.
There are two menus on the driver for changing the color of the print result: [Color Correction] and [Spot Color Setting]. [Color Correction] changes the overall color, and there are color correction engines in the printer, in the OS, and in certain applications. The setting selected in [Color Correction] in the printer driver specifies which color correction engine to use and also passes input parameters to each color correction engine. Only one setting can be selected for [Color Correction Method]. Therefore, no color correction engine in the printer, in the OS, or in a particular application will be used at the same time, but only one of them will be used.
[Spot Color Setting] replaces the specified specific color (= the original color) with another color (= the target color), and there is a color replacement engine in the driver and in the printer. When [Color Correction] is set to [Epson Vivid Color] or [Epson Preferred Color], which uses the printer's internal color correction engine, color correction can be performed in combination with [Spot Color Setting]. When [Color Correction] is set to [ICM] or [None], color correction cannot be performed in combination with [Spot Color Setting].
This is because if the application or OS color correction is performed first, the RGB values before conversion specified in [Spot Color Setting] will be changed, and the printer driver will not be able to find the part to be converted. 277 Setting on the driver By What is the Color Correction Performed?
