Recipe Details
Ingredients
oil-based chemical, water-based chemical, oil-based ink
Preparation Steps
The offset lithographic technique is based on the chemical principle that water repels oil. In this method, the printing area is defined by an oil-based chemical applied to the plate. The entire surface is then dampened with a water-based chemical before inking. The oil-based ink then adheres exclusively to the oily, non-watered areas of the surface to create the image (p. 348).

Evidence
"...the ink, which is also oil-based, adheres exclusively to the oily areas of the printing surface."
Remarks
This ink technology allowed for the 'printed manuscript' boom in Kano, where hand-drawn calligraphic scripts were transferred via negative film to press plates, preserving the handwritten tradition in a mechanized format (p. 348, 351).
