Hi Neil,
Happy New Year to You.
I would love to see you at PPF one of these days. Many of us can answer specific questions about the 3880. I use one but not with Colorburst, though I and others have experience with QTR. I agree with Ernst that Jeff Schewe's printing book is quite excellent, I have it and could bring it to a PPF meeting for you to look at. I use it too often to loan it though.
Eric
