PRECISION ENLARGING PRINTER (4X).

Abstract

This report covers the test and evaluation of the Precision Enlarging Printer (PEP). The PEP is a 4-time-enlarging, projection-type printer designed to produce outputs with negligible distortion and extremely high resolution. The operation of the printer has been automated extensively to increase efficiency of operation as well as accuracy of the printer. Tests were conducted to determine the design and operational characteristics of the printer with primary emphasis being placed on the distortion and resolution characteristics. The report concludes that: (a) The PEP will produce outputs with an Area Weighted Average Resolution (AWAR) of at least 150 lines/mm at the negative plane; (b) the distortion of the optical system does not exceed a Circular Probable Error (CPE) of 2.65 microns at the scale of the negative; (c) the enlarging ratio of the PEP is 3.94; (d) the rate of production with the PEP is comparable with that of other widely used similar printers; and (e) the PEP is a relatively easy instrument to operate and requires very little maintenance.
