My Mac monitor and Epson R2880 printer are now both calibrated. After some research I chose X-Rite ColorMunki Photo software and it was reasonably easy to set up. The cost of this software--£295--- may prevent some from making the purchase but I decided to use some Xmas gift money towards it and feel it is money well spent.
I have been advised by a couple of OCA students on the Flickr site that prints may appear dark using the combination of a Mac and ColourMunki and to increase the brightness prior to printing. This is something I am now aware of and will need to be prepared for some initial trial and error .
