1. A method for printing in grayscale, comprising:
receiving, by a processor, a source profile of a color image; converting, by the processor, the source profile into a device specific color space profile; converting, by the processor, the device specific color space profile into a grayscale device specific color space profile that only has black separation values for each output node using a destination profile that is device specific, wherein the destination profile comprises a first table for converting a device specific color space to a device independent color space and a second table for converting only k values of the device specific color space to the device independent color space using only a lightness value of the device independent color space, wherein the device independent color space comprises an L*, a*, b* color space, wherein L* represents the lightness value and a* and b* represent a chroma coordinate value of a corresponding color in the source profile; and printing, by the processor, the color image in a grayscale using the grayscale device specific color space profile that reproduces a tone of each color of the source profile of the color image. |
