The Printing Ink Manual was first published in 1961 under the auspices of the Society of British Printing Ink Manufacturers with the object of providing an authoritative work on printing ink technology. This, the fourth edition, continues that purpose and presents a comprehensive study of the current ‘state of the art’ in the ink industry. For those starting in the printing ink industry it is a textbook dealing with all aspects of the formulation and manufacture of printing ink. For the ink technician it is a practical manual and useful source of reference. For printers and users of printed material the manual supplies helpful information on the nature and behaviour of ink both on the printing press and as the finished print. Readers with a little scientific knowledge will have no difficulty in using the manual, but as in previous editions, sufficient chemistry and physics have been introduced to assist the advanced technician and research scientist.
