The earliest decorated biscuit tin was commissioned in 1868 by Huntley & Palmers from the London firm of De La Rue to a design by Owen Jones. Early methods of printing included the transfer process (essentially the method used to decorate porcelain and pottery since about 1750) and the direct lithographic process, which involved laying an inked stone directly on to a sheet of tin. Its disadvantage was that correct colour registration was difficult. The breakthrough in decorative tin plate production was the invention of the offset lithographic process. It consists of bringing a sheet of rubber into contact with the decorated stone, and then setting-off the impression so obtained upon the metal surface. The advantages over previous methods of printing were that any number of colours could be used, correctly positioned, and applied to an uneven surface if necessary. Thus the elaborately embossed, colourful designs that were such a feature of the late Victorian biscuit tin industry became technically possible.
