Re: [Digital BW] IJC Curve design - Tonning.

Peter, Ah, a brave man, indeed...sounds like you're designing a family of curves from scratch! I would suggest looking at some of the Bowhaus supplied profiles for a similar paper to see what they did with the ink limits and curve shape for the colored inks. I believe most of their profiles do not use Cyan or Magenta at all! Using an existing curve as a base should get you in the ballpark pretty fast. Good luck, Alan Huntley

Hi all I have successfully designed the black and light black curves and linearised using an eyeone. So far so good. However the tone of the print is anything but neutral. I think it looks a little green !! So I have been trying to use light cyan and light magenta curves to get a more pleasing tone. This part I have found very frustrating. Can anyone give me some tips or general advice on a logical way to proceed. Many thanks Peter.
