Line Separations from Transparencies for Textile Printing Using a Monochromator.

At present, line separations are made by hand, which is costly and time consuming. An experiment is described in which an opaque color original to be reproduced on cloth for the textile industry is line separated photographically by first making a conversion on color duplicating film, and then making line separations using a monochromator and a pan lith film. The monochromator, which can be visibly tuned to any wavelength, acts as a light source with a very narrow band filter. It permits the separation of a large number of colors. This technique is applicable to reproducing color patterns on paper as well as on cloth.
