Abstract

Abstract A diazo printing system comprises a source of ultraviolet radiation and an optical system including lenses that are transparent to ultraviolet radiation. The optical system directs radiation generated by the source through an intermediate, and focuses an enlarged or reduced image of the intermediate on a diazo layer. In accordance with the preferred embodiment of the invention, the diazo printing system is employed in a garment layout system that further includes a system for recording the image of an array of miniature garment patterns and thereby forming an optically enlargeable intermediate. The intermediate is employed in the diazo printing system to form a full size reproduction of the miniature patterns and the full size reproduction is employed in the cutting of cloth.
