Epson T5000 User Manual

Even when using the same image data, the original image and the displayed image may 
look different, and the printed results may look different from the image you see on the 
display. This occurs due to the difference in characteristics when input devices such as 
scanners and digital cameras capture colors as electronic data, and when output devices 
such as display screens and printers reproduce colors from the color data. The color 
management system is a means to adjust differences in color conversion characteristics 
among input and output devices. As well as applications for image processing, each 
operating system is equipped with a color management system, such as ICM for Windows 
and ColorSync for Mac OS X.

In a color management system, a color definition file called a "Profile" is used to perform 
color matching between devices. (This file is also called an ICC profile.) The profile of an 
input device is called an input profile (or source profile), and of an output device, such as a 
printer, is called a printer profile (or output profile). A profile is prepared for each media type 
in this printer’s driver.

The color conversion areas by the input device and the color reproduction area by the 
output device differ. As a result, there are color areas that do not match even when 
performing color matching using a profile. In addition to specifying profiles, the color 
management system also specifies conversion conditions for areas where color matching 
failed as "intent". The name and type of intent vary depending on the color management 
system you are using.

You cannot match the colors on the printed results and display by color management 
between the input device and the printer. To match both colors, you need to perform color 
management between the input device and the display as well.
