Abstract
A method, apparatus and non-transitory computer readable medium for printing in grayscale are disclosed. For example, the method includes receiving a source profile of a color image, converting the source profile into a device specific color space profile, converting 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 and printing the color image in a grayscale using the grayscale device specific color profile that reproduces a tone of each color of the source profile of the color image.
