Abstract
The development of fast‐ colour printing is traced from the discoveries of indanthrone and the formalde‐hyde‐sulphoxylates up to the present day. The relatively minor changes in machine printing technique since Bell's day are discussed, and screen printing is dealt with briefly.Some of the printer's hopes for the future are then considered. These include provision of an effective discharge agent for anthraquinonoid vats, and a discharge agent which does not attack the disulphide bonds of wool. The possible improvement of pigment printing colours is discussed, and the deficiencies of agera are touched on. Finally, the problem of the ideal printing thickener is dealt with in some detail.
