ABSTRACT:
Lens alignment means is provided whereby mis-alignment is amplified by a lens system, is detected by a photocell array, is electrically encoded, and the coded information is stored and used to correct electronically the character placement so as to properly position characters on the film. A detailed description of this feature appears herein under the heading "CHARACTER ALIGNMENT", and in FIGS. 18 through 20 of the drawings. Master characters are packed more densely on the matrix by allocating each an area comprising one-third to two-thirds of the usual character area, and using a separate illumination device to illuminate each such separate area. The illumination devices can be energized in different combinations to illuminate characters of various sizes. A detailed description of this feature appears herein under the heading "CONCENTRATION OF MASTER CHARACTERS", and in FIGS. 34 through 40 of the drawings.
