ABSTRACT:
In a photocomposition machine, a method for projecting characters at a selected point size. A first reference position and a second reference position are defined. The variator lens and the collimator lens of the machine are driven to the first and second reference positions, respectively, in predetermined directions. The variator lens is then driven from the first reference position to a first composing position, and the collimator lens is driven from the second reference position to a second composing position. The composing positions are determined by the point size data, and each lens is moved to a composition position only in a direction opposite the predetermined direction.
