Abstract : Under a Contract, Delta Information Systems scanned four test documents at five resolutions and stored the resultant data on magnetic tape. Two sets of tape were generated - a one bit set and an 8 bit set. In the 1 bit set, each picture element is binary. In the 8 bit set, each picture element can have 256 possible gray shades. This report is an addendum to the previously delivered users manual. The purpose of this project is to print out the forty images on tape to verify their visual characteristics. In the case of the one bit/pel image the objective is to insure that all extraneous pels have indeed been removed. In the cases of the eight bit/pel image the purpose is to determine the general nature of the extraneous pels. All images were printed on a Versatec V-80 plotter capable of printing only black or white pels and having a resolution of 200 pels/inch. In the case of the 8 bit/pel images only the most significant bit of the 8 bits was printed.
