Also used when using host based color correction. When the application color correction is paramount and the need to ensure the printer s color correction algorithms are not used. To print color images in monochrome grayscale. Monitors display color using the RGB model, whereas printers are based on the CMYK model. Hence there are some colors that are visible on a monitor that cannot be printed and vice versa.
All devices have unique and different color gamuts.
In this mode, if RGB data is received, color correction will be applied. If CMYK data is received, no color correction is applied. Output from CMYK is intended for users doing pre-press work. CMYK output will provide users with an approximation of SWOP or Euro Standard color printing. Based on a mathematical model representing a standard RGB display monitor.
