I already edited a photo to look great in photoshop, but then I realized it can't be printed out properly being it's in rbg, and print files need to be in cmyk. How do I properly convert this image so that it looks as if it were still in rgb, but really a cmyk image? Below is how it looked after trying to convert rgb to cmyk...
