A color processing method comprising the steps of: subjecting device color data output under the condition of a first total area coverage value to a colormetric process by a colorimeter to acquire colorimetry values associated with device color data; storing a profile including the acquired association between the device color data and the colorimetry values, and for storing control information for controlling a colorant amount including an input second total area coverage value, wherein the second total area coverage value is set as less than the first total area coverage value; setting a total area coverage limitation process based on the control information; and characterised by: generating a 3D lookup table for converting an intermediate color space into a device dependent color space configurable by a total area coverage value, applying the second total area coverage value to the 3D lookup table to generate first conversion data for converting values of the intermediate color space into values of the device dependent color space limited by the second total area coverage value, and using the stored association between colorimetry values and device color data to modify the first conversion data into second conversion data for converting the intermediate color space into a device independent color space limited by the second total area coverage value, wherein sampling values for the whole intermediate color space, are converted into device-independent values limited by the second total area coverage value using the second conversion data, and a color gamut of the second total area coverage value is acquired by forward converting the device-independent values into color appearance space values based on an output-side appearance condition.. subjecting device color data output under the condition of a first total area coverage value to a colormetric process by a colorimeter to acquire colorimetry values associated with device color data; storing a profile including the acquired association between the device color data and the colorimetry values, and for storing control information for controlling a colorant amount including an input second total area coverage value, wherein the second total area coverage value is set as less than the first total area coverage value; setting a total area coverage limitation process based on the control information; and characterised by: generating a 3D lookup table for converting an intermediate color space into a device dependent color space configurable by a total area coverage value, applying the second total area coverage value to the 3D lookup table to generate first conversion data for converting values of the intermediate color space into values of the device dependent color space limited by the second total area coverage value, and using the stored association between colorimetry values and device color data to modify the first conversion data into second conversion data for converting the intermediate color space into a device independent color space limited by the second total area coverage value, wherein sampling values for the whole intermediate color space, are converted into device-independent values limited by the second total area coverage value using the second conversion data, and a color gamut of the second total area coverage value is acquired by forward converting the device-independent values into color appearance space values based on an output-side appearance condition.. generating a 3D lookup table for converting an intermediate color space into a device dependent color space configurable by a total area coverage value, applying the second total area coverage value to the 3D lookup table to generate first conversion data for converting values of the intermediate color space into values of the device dependent color space limited by the second total area coverage value, and using the stored association between colorimetry values and device color data to modify the first conversion data into second conversion data for converting the intermediate color space into a device independent color space limited by the second total area coverage value, wherein sampling values for the whole intermediate color space, are converted into device-independent values limited by the second total area coverage value using the second conversion data, and a color gamut of the second total area coverage value is acquired by forward converting the device-independent values into color appearance space values based on an output-side appearance condition..
