So why not just use QTRGui? Well, I'd be fine doing this if I could figure out how to make a custom paper profile for QTR using my densiometer. I don't feel I have the knowledge to write a description from scratch (I don't feel like I have the knowledge or understand the process to make the ink descriptions, but I would certainly be open to learning).
However, let me ask you this: Do you think that starting from a paper profile for my printer that seems similar to the paper I am using, and then using my densiometer to redo the gray curve and then linearize is a viable method? This seems doable.
