Black and White Illustration
Before the internet, if you wanted somebody to see your product or understand your process or know how to operate your machine, you had to print it on paper. Printing in just black was cheap; color? Not so much, so there was a huge demand for black and white illustration. With the web and inexpensive digital printing almost everything is in color now, but a small niche still remains for monochromatic renderings.
There are primarily two kinds of art here: “scratchboard” and “rubylith”. If you want to know more about either of these, go to my Deep Thoughts page.
