In Printing Colour 1400-1700, Ad Stijnman and Elizabeth Savage offer the first handbook of early modern colour printmaking before 1700 (when most such histories begin), creating a new, interdisciplinary paradigm for the history of graphic art. It unveils a corpus of thousands of individual colour prints from across early modern Europe, proposing art historical, bibliographical, technical and scientific contexts for understanding them and their markets. The twenty-three contributions represent the state of research in this still-emerging field. From the first known attempts in the West until the invention of the approach we still use today (blue-red-yellow-black/'key', now CMYK), it demonstrates that colour prints were not rare outliers, but essential components of many early modern book, print and visual cultures.
