However, I think there is a fair difference between a company like IJM and what Richard is doing which as I understand it is basically making available some tools he has developed on a "see how you go with these" basis and is seeking to recover some reward for the effort he has made creating them. Richard also has a day job. I certainly wouldn't expect a lot of aftermarket care for the outlay involved, although I am sure Richard will provide that through various channels as he has been pretty helpful in his contribution to this and other forums to date.
The main thing here is that we have a number of very valid alternatives for digital black and white printing and are fortunate to have people who continue to develop products and solutions which they are prepared to share with all of us, often on pretty affordable terms. More importantly, the knowledge that people are prepared to share on forums like this enable us to all become better at our craft.
Richard, I'm looking forward to your book and to your tools for the K3 OEM inks.
