Thanks guys for the quick response.
I am in the UK and will definitely be on the look out for a vacuum frame, I could do with one really. I will have to scout around though because I am in the countryside! I plan to use Toyobo KM73 plates which I can get from a print suppliers in London and have joined a very well resourced print workshop that has a fantastic etching press and all the printing materials I could ever need, including plate cutters.
Keith - Thanks for the support, one of the key pieces I have read and re-read is your AG article on the process and it has inspired me to push on with photogravure work. I also have a book on the complete works of 'Camera Work' which I look at it constantly. It never ceases to amaze me what the 'greats' produced.
Gandolfi - Your work just inspires me anyway!
