Robinson a respected book illustrator, later known for his drawings of whimsically elaborate machines to achieve simple objectives.
These sheets here offered used by Constable in the production of Bill the Minder [1912] & Hans Christian Andersen's Fairy Tales [1913]. Presumed to be Constable file copies, the sheets demonstrate the myriad of steps in the photographic color separation process, based on the CMYK color model. CMYK refers to the four color inks in this printing process: cyan, magenta, yellow and key (or black). The model works by "partially or entirely masking colors on a lighter, usually white, background." The ink reduces the light that would otheerwise be reflected. Such a model is called subtractive because inks "subtract brightness from white."
In the 12 groups of illustrations are found examples of "subtractive" sheets from each of these inks used in the process. In the case of each illustration, these sheets are grouped togewther with sheets in which the inks have been combined to reveal full color examples, though often with different tonal qualities. In a classroom setting, this batch would undoubtedly prove useful for teaching the color reproduction process as it developed in commercial applications during the early 20th C.
