I am reading a short text on typography, which refers to the “flow line” without defining what it is. My dictionary has a non-typographic definition:
a route followed by a product through successive stages of manufacture or treatment.
which doesn’t shed much light. Google search results all say some variation of “the line on which the text is placed”. So, is the flow line the same thing as the baseline?
(A picture being worth a kiloword, graphical definitions would be very welcome!)
