Re: [Digital BW] Re: UT14 Lab Readings All Over the Place

Thanks Paul,

I'll play around with it some more.  I thought maybe I got some carts with
wrong inks in them.  I've read that MIS does that occasionally.

I might just chuck this and go with the EB6 set up.  Sounds like it might be
better anyway.  I went with U14 because I really like the Gold Fibre Silk
paper
