Wood engraving is a form of relief printmaking and traditionally a popular method for reproducing illustrations. The image is cut into the end grain of the wood using specialist tools, rather than the side grain used in woodcut. The image is usually small in scale, with the potential for exquisite detail due to the density of the wood. Printing a wood engraving requires a stiffer ink than that of woodcut, therefore traditional letterpress inks are most suitable for printing.
