One of the elements that made for the success of the project was the sensitive help given to us by our friendly inkmaker (just round the corner as it happens but probably the best in the business) Cranfield Colours Ltd in Cwmbran. We gave them small swatches of Ralph's Japanese paper proofs in the appropriate colours and asked for the inks to be as translucent as possible. They joked that all I had ended up with was a tin full of 'extender' with only a tiny amount of colour added but that is just what was needed so that, when another colour (even black) was printed on top of one already printed it did not obliterate it but formed another colour. There are many lovely examples in this book of this technique,
