Benjamin Henry Day, Jr. was an illustrator and printer, he contributed to Mark Twain’s semi-autobiographical traveling journey, “A Tramp Abroad,” published over 100 years ago, in 1880.
Known mainly for his invention of the Ben-Day dot printing process, which consists of small dots spaced at different intervals to achieve certain effects, colors and illusions. Ben-Day dots were used in the pulp comics of the 1950’s and 1960’s as they were an inexpensive method for providing shading, secondary color and most famously, flesh tones.
