In his classic 1935 volume, History of , Arthur Hind illuminated manuscripts, block-printed cloth, texts,5 concluded that the ‘hand-colouring’ of fifteenth-century and hand-coloured prints. While these sources woodcuts had not been studied as much as it deserved provide valuable insights into materials and practices, and that ‘a systematic record of the various colours… they do not directly address woodcut colour printing inks. would probably be of considerable value to localise iso- The only known contemporary reference to early mod- lated cuts.’1 His commentary would apply throughout the ern colour printing ink for woodcuts is ’s remainder of the twentieth century.
