My role of Ilford GFS is used up and we are now going to try a roll of Canson Infinity Baryta Photographique. Thanks John B. at Vistek for your advice!
The roll of paper is in the HP Z3100 and profiled. Now what to print? Black and white or colour?
I've printed the first large print and this is one fine paper. The first print was this image http://www.johngreen.ca/2013/12/snow-fall-from-front-door.html
