Abstract

A high resolution printing head for a line printer using photographic recording medium has a plurality of modules connected to form a two dimensional printing array. Each module has three fiber optic ribbons bonded together to form a staggered array of fibers. An apertured mask is photolithographically attached to the two dimensional array so that there is one aperture positioned over each fiber. The aperture has a cross-section less than the fiber so there is no overlapping of output light from each fiber and the apertures are also staggered so that a three fold increase in line density is achieved over conventional single ribbon arrays.
