I'm sorry to hear that you spent 4 days on this... The quad files that are used and selectable in the curves drop down in the QTRqui are stored in a different folder than the .qidf files. When you click show curve in the curve creation module it will create the .quad file based on those inputs and put it in the folder here: c:\Program Files\QuadToneRIP\QuadTone\quad3880 You will probably need to create a quad4900 folder in the same location as all the quad folders and then rename and drag the .quad file in the quad3880 folder into the new quad4900 folder. Hope that helps, Richard Boutwell
