In a dry silver photographic imaging device and method, two laser beams are generated. The laser beams are then modulated. One of the modulated laser beams is reflected and the other modulated laser beam is transmitted. The two beams are then swept across a dry silver film in order to form a desired image on the film.

Dry silver photographic imaging device and method

A plurality of halftone screen density data structures utilizing halftone dot patterns which arrays the halftone dots at preselected screen angles and at a preselected distance to create a screened halftone separation. By arraying the halftone dots at preselected screen angles, the human eye is confused into perceiving continuous patterns and is less likely to perceive any Moire pattern than when using conventional methods. The data structures are created by arranging for every halftone dot in at least one halftone dot pattern of the data structures to be surrounded by a plurality of dots having their dot centers at preselected screen angles and at a preselected distance from the dot center of the center halftone dot. The halftone dots are superimposed over a plurality of bits arranged as a bit map which is representative of a pixel format utilized to produce screens wherein each bit in the bit map is assigned a value in a predetermined fashion. The values are utilized when binary representations of the density of an image for a sampled area are transformed to pixel format. Through this process, the halftone screen density data structures are utilized to transform binary representations of images to a pixel format which is utilized to reproduce a desired artwork.
