Abstract

Art-work masters for LSI photo processing may be produced in multiple transparencies dyed colors for visual contrast. The image parts to be contrasted are placed in registration in successive, different, colored transparent dye layers by successively applying photosensitive dye layers to a glass substrate and imagewise exposing each layer to image-patterned actinic radiation before applying the next layer. The "clear" parts of each exposed layer can be developed in a spray, containing 2% ammonia hydroxide plus water, before applying the next layer.

Multicolor Art Work Generation for Precision Geometries and Registration

Art-work masters for LSI photo processing may be produced in multiple transparencies dyed colors for visual contrast. The image parts to be contrasted are placed in registration in successive, different, colored transparent dye layers by successively applying photosensitive dye layers to a glass substrate and imagewise exposing each layer to image-patterned actinic radiation before applying the next layer. The "clear" parts of each exposed layer can be developed in a spray, containing 2% ammonia hydroxide plus water, before applying the next layer.

After visual inspection, the working plates for each image layer may be constructed by inserting the appropriate color filter between the master plate and the working plate. Alternately, the master plate can be used as a working plate in projection printing by using appropriate color filters to filter out or absorb the desired layer or layers.
