Looks like your software is applying some type of color management to the Ink Separation Page. I struggled for years with Adobe Photoshop and Mac to print with No Color Management and it is essentially difficult or impossible after CS3. My advice would be to purchase the Print Tool, which makes calibration of your digital negatives very easy by assuring that you can always print with No Color Management. The Print Tool has other nice features as well and is a great bargain for the price.
