+Total Ink Limit in OBC session will not changeThere is a known issue that will prevent a ProfileMaker session from OBC software from retaining changes in the total ink limit. To correct this problem, open your session in a text editor like TextEdit (Mac) or Notepad (PC) and follow the steps below.
In the header of the  ProfileMaker session you will see a line that says LGOMCCMYKSEPARATION "UseCMYKSep"  Replace that line COMPLETELY with the following text:  
LGOMCCMYKSEPARATION "UseCMYKSep = true Separation = {  SepID = 6 StartK = '40' WidthK = '1' MaxC = '100' MaxM = '100'  MaxY = '100' MaxK = '100' MaxCMYK = '400' } " 
You can then drag and drop the session into ProfileMaker  and change your separations without a problem.
