Photo Sciences, Inc. of Torrance, California has developed a unique approach to manufacturing custom digital gray scales using sophisticated micro-lithography techniques typically used to produce photomasks for the semiconductor industry. The custom digital gray scales produced by Photo Sciences are on glass or quartz plates with microscopic images etched into a chrome coating on one surface of the plate. The microscopic images consist of major pixels and sub-pixels (minor pixels) wherein the ratio of dark pixels to transmissive pixels determines the level of gray as light passes through the scale.
Photo Sciences has created proprietary software which creates the pixels and sub-pixels utilizing random dither, patterned dither and half-tone. The patterns can be created with extreme accuracy and the gray scale levels precisely controlled from region to region.
Photo Sciences proprietary process produces gray levels from 256 to 1024 with equivalent DPI's up to 2600 and actual DPI's up to 42,000.
