This message is for all and not specific to your question or sources. There is no subject in our business which has generated as steaming a pile of misinformation and confusion a color management. There is a book which I found to be the best book on the subject BY FAR. Your color management life will be divided into two parts... Before and after you read this book. You will look sheepishly back at the questions you have asked in the past and wonder what all the confusion was about. And, God's busy with other stuff.
The book is "Real World Color Management" by Bruce Fraser and others John O'Donnell � Technical Sales - Digital Photography Professional Graphics Systems & Services, Inc. 3 West Main Street Elmsford, NY 10701 (914) 345-3033 x34 John(AT)prographics.com > Hi > > I'm struggling with linearising an Epson 1290 and subsequent profiling.

'Col Management Off' has disappeared from the list and > 'Europ Prep Defaults' been replaced with 'Europ with EktachromeSpace', so I > can't get back to the original list options. I'd been using Col Man Off for > linearising and Europ Prep Defaults with the working space changed to > Ektachrome for printing with a profile.
