Years ago I downloaded that book (Abney and Clark's - Platinotype and its Preparation 2nd American Edition), it was a free PDF file.
I printed, gave it to somebody and lost the file.
Now impossible to find from where I got it.
Can somebody help me and give me the link.
Thanks
There is a link to the pdf on http://www.bostick-sullivan.com/techart.php but unfortunately it doesn't work. Try to check with them and see if they have it and if they can mail it to you.
