Duncan’s machine

A description of letter-press printing machines invented by Mr. George Duncan, an engineer, of Loverpool, who claims to be the inventor of two-colour printing machines, and believes that, by his machines, printing in two colors without removing the sheet is as easy of accomplishment as printing in one colour only, and at a very material savings of cost. The most exact register is secured, and the distributing arrangements are very effective—three rollers passing completely over the forme, thereby securing perfect distribution and uniformity of colour. The other descriptions of machines produced by the same manufacturer are called the “Diamond” Single Cylinder Printing Machines, and “Little Diamond” Jobbing Machine. An engraving of the latter is here given:—
