I've tried to find info which ICC profile is used for HSV (or RGB) to CMYK conversion, but still without success. It is stated somewhere? I think it is quite important for specific use.
Btw, it would be nice to have any possibility to choose one of predefined (e.g. Fogra 27, 39) or even upload custom ICC profile from local disk.
I agree. I've been looking to see what color space these rgb values are in. I'm guessing sRGB, but it would be nice to know.
