Composing on Master
from Fancyclopedia 2 ca. 1959
Or ON STENCIL or IN THE STICK Making up what you're going to say as you put it down on the stencil, or master, you'll use to run it off. A great deal of the contents of individzines, and editorials in other fmz, are composed this way, without dummying. The last expression comes from handset printing, where the letters for each line are set in a holder called a composing stick.
