Can someone explain this for me also, I'm having problem with a profile wich
I have done for a Bestrip where I get 0,0,1,0 CMYK when using this profile
in PS to seperate a 255,255,255 picture and I'm using Apple CMM. With
Heidelberg CMM I get 1,1,1,0 CMYK.

I'm using ProfilMaker 3.1.4 can I edit the profile in Profile editor to get
it right ?

I haven't used this software so much, so a short explanation would be great.

/Johan
