Had to do a google on that one Mike. Looked at the FAQ's I understood that and then went to the tutorial and got lost there. Can't see how that would integrate in Xara as it's more than libraries its colour management has to be programmed when doing conversions. When I started reading the tutorial I got to about the 8th page when my mind hazed over. Does it work like the import/export PDF filter which is bolted into xara's actual structure and all that a user has to do is to select a pre-programmed library to run?
