Thanks for the reply. Is there more than one way to create curves? If so, I don't know of any but using the curve creation tool in QTR which is how I did mine. I once tried editing a qidf file in a text editor, but that was long ago and the curve I'm using now was made in the QTR utility. Using the K3 inkset. I find no clogged jets when I run the Epson utility. Is there anywhere else I might look?
So... please expand on what an "ink profile" is, where I look to change or adjust it, and what I should look for.
